The Teclu burner is a laboratory gas burner, a variant of the Bunsen burner, named after the Romanian chemist Nicolae Teclu. It can produce a hotter flame than a Bunsen burner. The lower part of its tube is conical, with a round screw nut below its base. The gap, set by the distance between the nut and the end of the tube, regulates the influx of the air in a way similar to the open slots of the Bunsen burner.
|
|
Plating is thus often done in a laminar flow cabinet or on the working bench next to a bunsen burner.

With his laboratory assistant Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use.
|
|
Instruments used for dry heat sterilization include hot air oven, incineration or burning, flaming, radiation, microwave, bunsen burner, and glass bead sterilizer.
|
|
The Teclu burner provides better mixing of air and fuel, which is what allows it to achieve higher flame temperatures than the Bunsen burner.
|
|
The Bunsen burner was essential to the invention of the spectroscope by Robert Wilhelm Bunsen and Gustav Robert Georg Kirchhoff. Peter Desaga's son, Carl Desaga, founded C. Desaga.

A variety of Bunsen burner flames. Bunsen burners may be adjusted from a highly luminous flame (left) to a hotter 'roaring blue flame' (right) One of the most familiar instances of a luminous flame is produced by a Bunsen burner. This burner has a controllable air supply and a constant gas jet: when the air supply is reduced, a highly luminous, and thus visible, orange 'safety flame' is produced. For heating work, the air inlet is opened and the burner produces a much hotter blue flame.

Durham Geo. Flame temperatures of up to are achievable. Compared with a Bunsen burner, the lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and gas. The tube is wider, and its top is covered with a plate mesh, which separates the flame into an array of smaller flames with a common external envelope, ensures uniform heating, and also preventing flashback to the bottom of the tube, which is a risk at high air- to-fuel ratios and limits the maximal rate of air intake in a Bunsen burner.

Bunsen burner flames depend on air flow in the throat holes (on the burner side, not the needle valve for gas flow): 1. air hole closed (safety flame used for lighting or default), 2. air hole slightly open, 3. air hole half-open, 4.
|
|
The burner will often be placed on a suitable heatproof mat to protect the laboratory bench surface. A Bunsen burner is also used in microbiology laboratories to sterilise pieces of equipment and to produce an updraft that forces airborne contaminants away from the working area.

Using wire gauze with an alcohol burner A wire gauze is a sheet of thin metal that has net-like patterns or a wire mesh. Wire gauze is placed on the support ring that is attached to the retort stand between the Bunsen burner and the glassware to support the beakers, flasks, or other glassware during heating. Wire gauze is an important piece of supporting equipment in a laboratory as glassware cannot be heated directly with the flame of a Bunsen burner, and requires the use of a wire gauze to diffuse the heat, helping to protect the glassware. Glassware has to be flat-bottomed to stay on the wire gauze.

A pot of oil on a heat source An oil bath is a type of heated bath used in a laboratory, most commonly used to heat up chemical reactions. It's essentially a container of oil that is heated by a hot plate or (in rare cases) a Bunsen burner.
|
|
A water bath is used for temperatures up to 100 °C. An oil bath is employed for temperatures over 100 °C. The heated bath is heated on a hot plate, or with a bunsen burner. The reaction chamber (florence flask, erlenmeyer flask, beaker) is immersed in the heated bath.

Well known nickel organometalic (or organonickel) compounds include Nickelocene, bis(cyclooctadiene)nickel(0) and nickel tetracarbonyl. Nickel Nickel tetracarbonyl was the first discovered organonickel compound. It was discovered that carbon monoxide corroded a nickel reaction chamber valve. And then that the gas coloured a bunsen burner flame green, and then that a nickel mirror condensed from heating the gas.

Peter Desaga was a German instrument maker at the University of Heidelberg who worked with Robert Wilhelm Bunsen. In 1855, Desaga perfected an earlier design of the laboratory burner by Michael Faraday into the Bunsen burner. Neither Desaga nor Bunsen patented the design, and many imitations were marketed.Louis Rosenfeld, Four Centuries of Clinical Chemistry, 1999, n.p.

Spectrum of the blue (premixed, i.e., complete combustion) flame from a butane torch showing molecular radical band emission and Swan bands. Note that virtually all the light produced is in the blue to green region of the spectrum below about 565 nanometers, accounting for the bluish color of sootless hydrocarbon flames. Different flame types of a Bunsen burner depend on oxygen supply.

E. S. Topping named the peak Observation Mountain in 1872 as well, but that name did not stick. The Bunsen Peak Trail with its trailhead just south of Mammoth is a steep to the summit. Bunsen Peak was named for the German chemist Robert Bunsen, the inventor of the Bunsen Burner and responsible for early work on volcanic geyser theories.

To produce enough soot to be luminous, the flame is operated at a lower temperature than its efficient heating flame (see Bunsen burner). The colour of simple incandescence is due to black-body radiation. By Planck's law, as the temperature decreases, the peak of the black-body radiation curve moves to longer wavelengths, i.e. from the blue to the yellow.

Modern gas heaters have been further developed to include units which utilize radiant heat technology, rather than the principles of the Bunsen burner. This form of technology does not spread via convection, but rather, is absorbed by people and objects in its path. This form of heating is particularly useful for outdoor heating, where it is more economical than heating air that is free to move away.

Being large and thick-walled, It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source. This type of tube is used in the sodium fusion test. Ignition tubes are often difficult to clean due to the small bore. When used to heat substances strongly, some char may stick to the walls as well.

As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly. Therefore, crucible tongs come to play a key role when burning, or doing anything with hot objects. The major types of metals used to produce the tongs are stainless steel, brass, and nickel. Moreover, some of them also have a special characteristic.

The author examines Robert Bunsen and his history. Bunsen had passion for arsenic but an explosion left him half-blind for the rest of his life and because of this he created the Bunsen burner. He discusses many people who contributed to the periodic table, including Dmitri Mendeleev, the man accredited for creating the first periodic table. Mendeleev predicted other elements that were yet discovered.

Laboratory Tripod A laboratory tripod is a three-legged platform used to support flasks and beakers. Tripods are usually made of stainless steel or aluminium and lightly built for portability within the lab. Often a wire gauze is placed on top of the tripod to provide a flat base for glassware. Tripods are generally tall enough for a bunsen burner to be placed underneath.

In 2002, when asked what he wanted for his 50th birthday, he requested "a second hit". A concerted drive, including a poll (scrutinised by the Electoral Reform Society) to select the track, saw "Bunsen Burner" — with music sampled from the Trammps song "Disco Inferno" and lyrics devised to help his daughter with her chemistry homework – reach number nine in the UK Singles Chart on 6 October, and earned Otway an appearance on Top of the Pops, BBC Television's flagship popular music programme. To encourage fans to buy more than one copy each of the single, he released three different versions. The flip-side of "Bunsen Burner – The Hit Mix" was a cover of "The House of the Rising Sun" recorded at Abbey Road Studios and featuring 900 of his fans on backing vocals, each of whom was credited by name on the single's sleeve.

Fuel gases have been used in numerous applications. One of the earliest was gas lighting, which enabled the widespread adoption of streetlamps and the illumination of buildings in towns with a municipal gas supply. Fuel gas is also used in gas burners, in particular the Bunsen burner used in laboratory settings. It may also be used gas heaters, camping stoves, and even to power vehicles, they have high calorific value.

A simple way to produce some MgH is to burn magnesium in a bunsen burner flame, where there is enough hydrogen to form MgH temporarily. Magnesium arcs in steam also produce MgH, but also produce MgO. Natural formation of MgH happens in stars, brown dwarfs, and large planets, where the temperature is high enough. The reaction that produces it is either 2Mg + H2 → 2MgH or Mg + H → MgH.

Diffusion of heat takes place in rigid solids, but that is called heat conduction. Convection, additionally may take place in soft solids or mixtures where solid particles can move past each other. Thermal convection can be demonstrated by placing a heat source (e.g. a Bunsen burner) at the side of a glass filled with a liquid, and observing the changes in temperature in the glass caused by the warmer fluid circulating into cooler areas.

Dr. Bunsen Honeydew is a Muppet character from The Muppet Show, performed by Dave Goelz. He is a bald, yellow-skinned, bespectacled, lab-coated scientist who presented periodic science segments from "Muppet Labs, where the future is being made today." The character has no eyes, only completely transparent, lensless glasses, giving the appearance of a stereotypical absent-minded intellectual. His first name is derived from Robert Bunsen, after whom the Bunsen Burner was named.

Hot metal work glows with visible light. This thermal radiation also extends into the infrared, invisible to the human eye and the camera the image was taken with, but an infrared camera could show it (See Thermography). spark used to light this Bunsen burner emit light ranging in color from white to orange to yellow to red or to blue. This change correlates with their temperature as they cool in the air.

A Meker–Fisher burner, or Meker burner, is a laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations. The burner was introduced by French chemist Georges Méker in an article published in 1905.G. Meker.

Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents. The long, narrow neck of test tube slows down the spreading of gases to the environment. Test tubes are convenient containers for heating small amounts of liquids or solids with a Bunsen burner or alcohol burner.

1914) burned vaporized kerosene (paraffin); the vaporizer was heated by a denatured alcohol (methylated spirit) burner to light. When lit some of the vaporised fuel was diverted to a Bunsen burner to keep the vaporizer warm and the fuel in vapour form. The fuel was forced up to the lamp by air; the keepers had to pump the air container up every hour or so. This in turn pressurized the paraffin container to force the fuel to the lamp.

There are generally three types of fixation processes depending on the initial specimen: Heat fixation: After a smear has dried at room temperature, the slide is gripped by tongs or a clothespin and passed through the flame of a Bunsen burner several times to heat-kill and adhere the organism to the slide. Routinely used with bacteria and archaea. Heat fixation generally preserves overall morphology but not internal structures. Heat denatures the proteolytic enzyme and prevents autolysis.

Flaming is done to inoculation loops and straight-wires in microbiology labs for streaking. Leaving the loop in the flame of a Bunsen burner or alcohol burner until it glows red ensures that any infectious agent is inactivated. This is commonly used for small metal or glass objects, but not for large objects (see Incineration below). However, during the initial heating, infectious material may be sprayed from the wire surface before it is killed, contaminating nearby surfaces and objects.

By 1924, the hospital had shifted to a more psychoanalytic focus and Franz's salary and title were reduced after an employee in one of the laboratories left a door unlocked and a Bunsen burner ignited. Franz quickly resigned after the demotion. After leaving the hospital, Franz moved to California to teach at the University of California, Los Angeles (UCLA). While there, he was named a professor of psychology the following year and remained on the faculty until his death.

The lamp (made in approx. 1914) burned vaporized kerosene (paraffin); the vaporizer was heated by a denatured alcohol (methylated spirit) burner to light. When lit some of the vaporised fuel was diverted to a Bunsen burner to keep the vaporizer warm and the fuel in vapor form. The fuel was forced up to the lamp by air; the keepers had to pump the air container up every hour or so, pressurizing the paraffin container to force the fuel to the lamp.

Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner. While they do not produce flames as hot as other types of burners, they are sufficiently hot for performing some chemistries, standard microbiology laboratory procedures, and can be used for flame sterilization of other laboratory equipment.

A flower is on a piece of aerogel which is suspended over a flame from a Bunsen burner. Aerogel has excellent insulating properties, and the flower is protected from the flame. Despite the name, aerogels are solid, rigid, and dry materials that do not resemble a gel in their physical properties: the name comes from the fact that they are made from gels. Pressing softly on an aerogel typically does not leave even a minor mark; pressing more firmly will leave a permanent depression.

The Doctor and his companions decide to attract attention by starting a fire, succeeding in manoeuvring an aerosol can into the flames of the Bunsen burner gas outlet. This coincides with Smithers discovering the true virulence of DN6 and demanding Forester cease his licence application. In the lab, the makeshift bomb explodes in Forester’s face as PC Rowse arrives. Back in the TARDIS, the Doctor succeeds in returning the craft and crew to normal size, a process which cures Barbara of her infection by DN6.

From this work, the reciprocity law of Bunsen and Roscoe originated. He discontinued his work with Roscoe in 1859 and joined Gustav Kirchhoff to study emission spectra of heated elements, a research area called spectrum analysis. For this work, Bunsen and his laboratory assistant, Peter Desaga, had perfected a special gas burner by 1855, which was influenced by earlier models. The newer design of Bunsen and Desaga, which provided a very hot and clean flame, is now called simply the "Bunsen burner", a common laboratory equipment.

Many of her works were strongly influenced by chemical engineering, and especially the field's graphs which depicted physical properties of substances. Leiteritz's paintings typically reworked a mundane graph using large expanses of colour and a bold abstract theme, changing it into a dynamic painting. Other works are reminiscent of Bunsen burner flame or DNA gel. One of her most famous paintings, "Crossing at the Left Border" (1966; oil on linen), appeared on the cover of the catalogue for an art exhibition in Chicago in 1969.

A boiling tube is a small cylindrical vessel used to strongly heat substances in the flame of a Bunsen burner. A boiling tube is essentially a scaled-up test tube, being about 50% larger. They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow; a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of the surrounding liquid. This phenomenon is called bumping.

The crushed and broken lateral inscription band, meanwhile, was annealed with a natural gas bunsen burner before being reshaped with wood and Perspex levers. The two surviving strips edging the inscription band were manually reshaped, while the missing pieces, which may have been catapulted across the construction site by the excavator, were recreated with brass. The recreated strips did not repeat the engraved chevron pattern of the originals, creating a visible distinction between old and new. In its restored state, the inscription band was placed on the helmet with a cellulose nitrate adhesive.

Bunsen burner: leftmost: reducing flame, rightmost: oxidizing flame Oxygen rich butane torch flame Fuel rich butane torch flame In various burners, the oxidizing flame is the flame produced with an excessive amount of oxygen. When the amount of oxygen increases, the flame shortens, its color darkens, and it hisses and roars."The Anatomy of a Flame", in: "Jewelry concepts and technology", by Oppi Untracht, 1983, With some exceptions (e.g., platinum soldering in jewelry), the oxidizing flame is usually undesirable for welding and soldering, since, as its name suggests, it oxidizes the metal's surface.

Carl Bayer was born (March 4, 1847) in the Duchy of Upper and Lower Silesia in the Austrian Empire, which is now Poland. He attended Heidelberg University in Germany where he studied chemistry under Robert Bunsen from 1869-1871, the namesake of the Bunsen burner. At Heidelberg, Bayer received his doctorate degree in 1871 with a dissertation on the chemistry of indium which was discovered recently in 1863. After obtaining his doctorate, Bayer lectured for two years at Technische Hochschule in Brno, and then left to establish his own research company.

In it, Ehrlich presented the entire spectrum of known staining techniques and the chemistry of the pigments employed. While he was at the Charité, Ehrlich elaborated upon the differentiation of white blood cells according to their different granules. A precondition was a dry specimen technique, which he also developed. A drop of blood placed between two glass slides and heated over a Bunsen burner fixed the blood cells while still allowing them to be stained. Ehrlich used both alkaline and acid dyes, and also created new “neutral” dyes.

Originally, the gauze was heated with a Bunsen burner; later, a wire grid was heated electrically. The heat transferred to the air in the tube sets it into near half-wave resonance if the gauze is placed below the midpoint of the tube as shown in the figure on the right. There is no theoretically optimal position, as the wave speed upward is c0 + u, the convection speed, while the wave speed downward is c0 − u. Without a convection flow, the midpoint and the lower tube end are the best locations for heat transfer.

A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring. Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly.

Sterilization of an inoculation needle via alcohol burner The inoculation needle is sterilized using the aseptic technique. An open flame from an incinerator, a bunsen burner, or an alcohol burner is used to flame along the tip and the length of the needle that is to be in contact with the inoculum. For ease of manipulation it is common practice to hold the needle with the dominant hand as if handling a pencil. The needle will be flamed at a downward angle through the flame’s inner cone until it is red-hot.

Circus fire arts rely on a brightly luminous flame, ideally with minimal heat output In the simplest case, the yellow flame is luminous due to small soot particles in the flame which are heated to incandescence. Producing a deliberately luminous flame requires either a shortage of combustion air (as in a Bunsen burner) or a local excess of fuel (as for a kerosene torch). Because of this dependency upon relatively inefficient combustion, luminosity is associated with diffusion flames and is lessened with premixed flames. The flame is yellow because of its temperature.

Trying to convince the hospital staff that Robin is the unstable one, Lisa leaps in front of Robin's car to fake a hit-and-run. Soon after, she leaves Emma's toy rabbit in a boiling hospital bunsen burner for Robin to see. Perceiving this message as a threat to her child, Robin punches Lisa at the hospital, which prompts her suspension. Although still separated, Robin and Patrick concoct a scheme to make their break-up seem even more volatile in hopes this will lower Lisa's guard and Patrick will be able to coax a confession out of her.

Faraday succeeded in liquefying several gases, investigated the alloys of steel, and produced several new kinds of glass intended for optical purposes. A specimen of one of these heavy glasses subsequently became historically important; when the glass was placed in a magnetic field Faraday determined the rotation of the plane of polarisation of light. This specimen was also the first substance found to be repelled by the poles of a magnet. Faraday invented an early form of what was to become the Bunsen burner, which is in practical use in science laboratories around the world as a convenient source of heat.

The illumination gas was passed to a Bunsen burner, the flame of which would then increase or decrease in size at the same frequency as the sound source. Jim & Rhoda Morris at SciTechAntiques.Flame manometer Case Western Reserve University Physics Department The change in flame size was too fast to be easily seen with the naked eye and a stroboscope, usually in the form of a rotating many sided mirror was used to view the flame. The frequency of the sound could then be calculated from the apparent distance between the flame images in the mirror and the known speed of its rotation.

Dr. Bunsen Honeydew's moniker is derived from the traditional piece of lab equipment, the Bunsen burner, plus the fact that his head was shaped and colored like a honeydew melon. He was rumored to be modeled after Lew Grade, whose company ITC Entertainment produced The Muppet Show. Henson responded in a Judy Harris interview: One of his most endearing features is his lack of visible eyes, despite the fact that he wears glasses. Occasionally, Honeydew removes his glasses to clean them, or lifts them as if to get a better look at things, which is something of a running gag.

Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.. the 1911 Encyclopædia Britannica. He similarly discovered the principles of electromagnetic induction and diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology. As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as "anode", "cathode", "electrode" and "ion".

Alex later goes to the headmaster's office at school, being informed that his school headmaster, Mr. Bray, wanted to see him. Alex is startled to find the sixteenth and final clone, who resembles Alex and had escaped from the academy. The clone tries to shoot Alex in revenge for Grief's death, causing a fire and an explosion in a laboratory when he ruptures a Bunsen burner with a bullet. Alex runs up to the roof, to be followed by the clone, and the two fight ending with one of them falling into a hole in the roof due to the explosion, and the other being rescued by the fire service.

His "reactor" was a bored-out block of lead, and he used lithium from $1,000 worth of purchased batteries to purify the thorium ash using a Bunsen burner. Hahn posed as an adult scientist or high school teacher to gain the trust of many professionals in letters—and succeeded, despite misspellings and obvious errors. Hahn ultimately hoped to create a breeder reactor, using low-level isotopes to transform samples of thorium and uranium into fissionable isotopes. His homemade neutron source was often incorrectly referred to as a reactor, but it did end up emitting dangerous levels of radiation, likely well over 1,000 times normal background radiation.

Unlike a metalworking torch, or burner as some people in the trade prefer to call them, a flameworking torch is usually "surface mix"; that is, the oxygen and fuel (typically propane, though natural gas is also common) is mixed after it comes out of the torch, resulting in a quieter tool and less dirty flame. Also unlike metalworking, the torch is fixed, and the bead and glass move in the flame. American torches are usually mounted at about a 45 degree angle, a result of scientific glassblowing heritage; Japanese torches are recessed, and have flames coming straight up, like a large bunsen burner; Czech production torches tend to be positioned nearly horizontally.

The Elbogen meteorite is not only one of the oldest recorded falls in history, but also the very iron that Alois von Widmanstätten used to discover the hidden internal structure of iron meteorites in 1808. Instead of etching the iron to reveal these structures, analytic model previously discovered by G. Thomson in 1804, he heated a slab of the iron in the flame of a Bunsen burner and so had the figures that would be later named after him revealed. In 1811, Mr. K. A. Neumann, a professor of chemistry at the technical institute in Prague had a small piece sent to him for chemical analysis and recognized it as being a piece of a meteorite.G. T. Prior, Catalogue of Meteorites: With Special Reference to Those Represented in the British Museum Collection, pg.

On the left a rich fuel with no premixed oxygen produces a yellow sooty diffusion flame; on the right a lean fully oxygen premixed flame produces no soot and the flame color is produced by molecular radicals, especially CH and C2 band emission. Flame color depends on several factors, the most important typically being black-body radiation and spectral band emission, with both spectral line emission and spectral line absorption playing smaller roles. In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. In a laboratory under normal gravity conditions and with a closed air inlet, a Bunsen burner burns with yellow flame (also called a safety flame) with a peak temperature of about .

Lucy's role in the early episodes of season 6 is rather small, having only minor sub plots such as helping a young artist who is using cocaine or by urging Dr. Dave Malucci to come forward and admit his possible mistake when using a Bunsen Burner that was thought to have caused an explosion in the ER. Lucy clashed with nurse Carol Hathaway when they both make a plea for the last bed in a rehab clinic. The bed ultimately goes to Hathaway's patient, which creates renewed friction between the pair when the patient does not show up for treatment. Lucy also clashes with Dr. Cleo Finch when Finch undermines Lucy's judgment in regard to a young boy and his mother who both have alcohol abuse problems. Lucy is finally able to come into her own and show her potential in the Christmas episode "How the Finch Stole Christmas" when patient Valerie Paige comes to the ER in desperate need of a heart transplant.

The Center for Advanced Study Marsilius Kolleg, situated in House Buhl, was founded in 2007 Among historical scientific achievements of Heidelberg researchers features prominently the invention of spectroscopy, and of the Bunsen burner; the discovery of chemical elements Caesium and Rubidium; the identification of the absolute point of ebullition; and the identification and isolation of nicotine as the main pharmacologically active component of tobacco. Modern scientific psychiatry; psychopharmacology; psychiatric genetics; environmental physics; and modern sociology were introduced as scientific disciplines by Heidelberg faculty. Almost 800 dwarf planets, the North America Nebula, and the return of Halley's Comet have been discovered and documented at institutes of the Heidelberg Center for Astronomy. Moreover, Heidelberg researchers invented the process of plastination to preserve body tissue, conducted the first successful transplantation of hematopoietic stem cells, and recently developed a new strategy for a vaccination against certain forms of cancer, which earned Harald zur Hausen of the university the Nobel Prize in Physiology or Medicine 2008.

In the episode "Too Many Chiefs" (season one), Max tells Tanya, the KAOS informer whom he is protecting, that if anyone breaks in, to pick up the house phone, dial 1-1-7, and press the trigger on the handset, which converts it to a gun. The phone- gun is only used that once, but Max once carried a gun-phone, a revolver with a rotary dial built into the cylinder. In the episode "Satan Place", Max simultaneously holds conversations on seven different phones: the shoe, his tie, his belt, his wallet, a garter, a handkerchief, and a pair of eyeglasses. Other unusual locations include a garden hose, a car cigarette lighter (with the lighter being hidden in the car phone), a bottle of perfume (Max complains of smelling like a woman), the steering wheel of his car, a painting of Agent 99, the headboard of his bed, a cheese sandwich, lab test tubes (Max grabs the wrong one and splashes himself), a Bunsen burner (Max puts out the flame anytime he pronounces a "p"), a plant in a planter beside the real working phone (operated by the dial of the working phone), and inside another full- sized working phone.
