A nitrocellulose slide, nitrocellulose membrane, or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots. It is also used for immobilization of proteins in western blots and atomic force microscopy [15] for its nonspecific affinity for amino acids.
Nitrocellulose, dry or wetted with less than 25 percent water (or alcohol), by mass UN 0341: 1.1D: Nitrocellulose, unmodified or plasticized with less than 18 percent plasticizing substance, by mass UN 0342: 1.3C: Nitrocellulose, wetted with not less than 25 percent alcohol, by mass UN 0343: 1.3C
Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder .
[3]: 287–289 Nitrocellulose produces greater volumes of gas per volume of solid than black powder does, so nitrocellulose bulk powders were less dense than later smokeless powders. Nitrocellulose bulk powders designed for early straight-sided black powder rifle cartridges like the .32-40 and .38-55 were friable and easily crumbled. The ...
By 1936 improved DuPont process control produced batches conforming to published reloading data rather than requiring different charge specifications for each batch; [11] and those propellants have remained in production. Non-conforming batches were used to load commercial and military cartridges following traditional testing procedures.
French war powder in 1879 used the ratio 75% saltpeter, 12.5% charcoal, 12.5% sulfur. English war powder in 1879 used the ratio 75% saltpeter, 15% charcoal, 10% sulfur. [114] The British Congreve rockets used 62.4% saltpeter, 23.2% charcoal and 14.4% sulfur, but the British Mark VII gunpowder was changed to 65% saltpeter, 20% charcoal and 15% ...
Poudre B" is made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. "Poudre B" is made up of very small paper-thin flakes that are not white but dark greenish grey in colour. "Poudre B" was first used to load the 8mm Lebel cartridges issued in 1886 for the Lebel rifle.
