Hastily, he scraped a flat-edged scalpel along a tissue sample, hoping for maximum abrasion, and triturated the results.

In both methods, after filtration, the crystalline product is triturated with acetone. If no solid separates, ethyl acetate is added to precipitate the crude product. The product is then dissolved in hot ethanol and treated with decolorizing charcoal. Ethyl acetate is added to the filtered solution to precipitate the crystalline product.

Detection of viral hemagglutinin also has been recommended as a diagnostic technique. Tissues are triturated in diluent and then sedimented by centrifugation. The supernatant fluid is tested for agglutinating activity for guinea pig erythrocytes. This test requires a minimum of laboratory equipment and is effective in the absence of antibody.

Adults feed primarily on wood, while larvae stages eat materials composed of fungi, wood and parental secretions. Burrowing within rotting logs offers the triturated wood that is a staple in the diet of these beetles, this wood is consumed widely by the males and then further broken down through the digestive tract, and eventually expelled for the eventual re- consumption by all family members.

For the isolation of biologically active compounds from organisms, several different steps need to be completed. The different steps required to obtain a biologically active compound are: Extraction, chromatographic purification, dereplication, structure elucidation and bioassay testing. The steps do not have to follow that particular order and many steps may be completed simultaneously. In the first step, the sample may be triturated and extracted with a suitable solvent or macerated.

For example, the amount of hormone in a dose of Levonorgestrel formulated as a progestogen-only contraceptive is only 30μg, which is far too small to handle. In a typical product, the drug is triturated with c. 1700 times its mass of sugar before being compressed and coated to produce the final tablet. In juicing, a triturating juicer is a style of juicer used to break down fresh produce into juice and fiber.

Ipomoea purga is described as a vine that can reach heights of . When fresh, the root is black externally, white and milky within, and varies in size according to its age. It has heart shaped leaves and purple trumpet like flowers. Ipomoea purga is rather difficult to break down, but if triturated with cream of tartar, sugar of milk, or other hard salts, the process of pulverization is much easier, and the powder rendered much finer.

A ten-minute treatment of small tissue pieces (less than 1 mm3) will allow papain to begin cleaving the extracellular matrix molecules holding the cells together. After ten minutes, the tissue should be treated with a protease inhibitor solution to stop the protease action. Left untreated, papain activity will lead to complete lysis of the cells. The tissue must then be triturated (passed quickly up and down through a Pasteur pipette) to break up the pieces of tissue into a single cell suspension.
