Set of NVP for photometric determination of surfactants
Set of NVP for photometric determination of surfactants allows you to quickly and accurately carry out photometric determination of the mass concentration of surfactants in an aqueous solution using a KFK-3-01 photometer or a similar device. The analysis is carried out in accordance with the procedure for measuring the mass concentration of surfactants in a solution using the photometric method in accordance with GOST 31857-2012. The kits include the official GOST text (RD, PND F), special reagents, membrane filters, standards (if necessary). Surfactants (surfactants) are chemical compounds that, concentrating on the interface, cause a decrease in surface tension. Thanks to their detergent, wetting, emulsifying, dispersing and other valuable properties, surfactants are widely used in the production of detergents and cleaning products, cosmetics and pharmaceuticals. Most of the surfactants (estimated at 55-60%) are used for the production of synthetic detergents (SDCs). Manba: https://www.nv-lab.ru/catalog_info.php?ID=2369
