BeJUNK12 and BeJUNK18

Bergmann-Junk (STANAG 5A/5B) and Bergmann-Junk-Siebert (STANAG 5C) tests are traditional methods for the quantitative determination of chemical stability of nitrocellulose and other nitrate esters, single and double-based smokeless powders, rocket fuels and nitro compounds. BeJUNK12 and BeJUNK18 testing apparatus present a cost-effective and modern solution for R&D and quality assurance laboratories across the branch. Efficient metal heating block, LCD touch screen interface are combined into standalone apparatus. The device can be connected to a PC for an online acquisition of temperature values and remote operation. Quality glassware and rigid tubes holder improve the operation effectivity.
