"Ytterbium ions are an ultraclean quantum system allowing us to carefully test how our approach performs," Biercuk told Motherboard in an email.

2009 – Johnson & Johnson directly attacked its main competitors stating that Reach UltraClean floss removes up to two times more plaque than Glide (Procter & Gamble) floss and that UltraClean Toothbrush removes more plaque and provides improved gum health versus the Colgate 360° toothbrush. Based on clinical trials the company also stated that Reach UltraClean Toothbrush removes up to 90% of plaque in places that are hard to reach. 2010 – Total Care Floss Clean toothbrush designed by Fuseproject won IDEA 2010 award.

One of LS9’s premier products is its UltraClean diesel. This diesel product offers numerous benefits in comparison to both regular diesel fuel, as well as traditional biodiesel. LS9 diesel is above the competition in many varying facets including cetane number, sulphur content, aromatic compound content, cloud point and oxidative stability. In 2010, LS9 UltraClean Diesel was awarded status as an officially registered fuel by the United States Environment Protection Agency (EPA).

2001 – Reach partnered with Warner Bros. and created Harry Potter Toothbrush for the start of Harry Potter and the Philosopher's Stone movie. 2006 – Fuel Industries developed a globe-trotting animated advergame "Mr. Reach: In the Mouth of Mystery" for Johnson & Johnson Canada, featuring various Reach dental products and Mr. Reach character. 2008 – In August 2008 Reach introduced Reach UltraClean toothbrush and floss.

A fuel’s cetane number is measurement of the combustion quality of diesel fuel during compression ignition. Fuels with higher cetane number have shorter ignition delays, providing more time for the fuel combustion process to be completed. Generally, diesel engines operate well with a CN from 40 to 55, whereas LS9 UltraClean has a CN of 70. In North America, most states adopt ASTM D975 as their diesel fuel standard and the minimum cetane number is set at 40, with typical values in the 42-45 range.

2003, European Union: Brussels respectively, while the U.S. federal specifications limit aromatics to 35%Control of Air Pollution From New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements: Final Rule, in 40 CFR Parts 69, 80, and 86. 2001. Soot production plays a major role in smog and environmental concerns, causing for these restrictions to be put in place. LS9 UltraClean diesel has been shown to have no aromatic compounds, whereas fossil fuel diesel contains approximately 10% by volume aromatics.

Uncrewed spacecraft in Earth orbit are an essential technology of modern civilization. They allow direct monitoring of weather conditions, relay long-range communications like television, provide a means of precise navigation, and allow remote sensing of the Earth. The latter role serves a wide variety of purposes, including tracking soil moisture for agriculture, prediction of water outflow from seasonal snow packs, detection of diseases in plants and trees, and surveillance of military activities. The deep vacuum of space could make it an attractive environment for certain industrial processes, such as those requiring ultraclean surfaces.

"Natural", he insisted, was limited to concentrations of lead that existed in the body or environment before contamination by humans, which has occurred frequently due to technological advancements and cultural traditions. Due to his ultraclean chamber, considered one of the first clean rooms, his measurements of isotopic ratios were free of the contamination that confounded the findings of Kehoe and others. Where Kehoe measured lead in "unexposed" workers in a TEL plant and Mexican farmers, Patterson studied mummies from before the Iron Age and tuna raised from pelagic waters. Kehoe claimed that humans had adapted to environmental lead.

In 2013 the Society for Mining, Metallurgy and Exploration published an article highlighting this specific application. It was mentioned that the use of the filter press is very beneficial to plant operations, since it offers dewatering ultraclean coal as product, as well as improving quality of water removed to be available for equipment cleaning. Other industrial uses for automatic membrane filter presses include municipal waste sludge dewatering, ready mix concrete water recovery, metal concentrate recovery, and large-scale fly ash pond dewatering. Many specialized applications are associated with different types of filter press that are currently used in various industries.

Particle levels must be controlled to nm sizes, and current trends are approaching 10 nm and smaller for particle control in UPW. While filters are used for the main loop, components of the UPW system can contribute additional particle contamination into the water, and at the point of use, additional filtration is recommended. The filters themselves must be constructed of ultraclean and robust materials, which do not contribute organics or cations/anions into the UPW, and must be integrity tested out of the factory to assure reliability and performance. Common materials include nylon, polyethylene, polysulfone, and fluoropolymers.

In 1979, Professor Needleman had published a seminal paper in the New England Journal of Medicine that demonstrated dose-dependent relationships between elevated levels of lead in shed milk teeth and a host of negative outcomes in children, including distractibility, hyperactivity lower IQ and a tendency to get easily frustrated. Clair Patterson had built an ultra-clean laboratory in the early fifties in order to measure the minuscule quantities of lead isotopes in an iron meteorite from the birth of the solar system; by which means he was able to date the age of the Earth at 4.55 billion years, an estimate that has never been superseded. Using his ultraclean facility, Patterson was able to demonstrate that natural levels of lead in prehistoric and pristine samples were orders of magnitude lower than official estimates, most of which were measuring lead contamination. His key contribution was his “measles diagram” demonstrating that if the lead burden of a pre-technological human was represented by one dot, and a patient with clinical lead poisoning was represented by 2000 dots, then the lead burden of a typical adult living in Western society was represented by 500 dots.
