Thermo Scientific RBS Solid is a low-foaming, surface-active powdered detergent formulated for use in automatic laboratory dishwashing machines. The cleaning detergent is mixture of anionic and nonionic surfactants. RBS™ Solid is strong enough to remove biological residues from plastic and glass, yet it is fully biodegradable and rinses away thoroughly to leave no residue. Use RBS Solid at approximately 10 to 30g per 10L of water in the wash cycle in automatic washers. For best results, use a water temperature of approximately 80°C. The low-foaming, surface-active powder is ideal for use in washing machines equipped with a power dispenser. Complete removal of all impurities and contaminants from glassware is a necessity for most laboratory applications. For many years, caustic alcohol and chromic acid solutions were used for many substances that could not be cleaned from glassware by ordinary detergents. These strongly acidic or strongly basic cleaning products reduce the lifespan of glassware while exposing the user to potential harm. By contrast, Thermo Scientific RBS 35™ and PCC-54 Products are mildly basic, biodegradable, surfactant concentrates containing anionic and nonionic detergents. The surfactants clean by penetrating between contaminating substances and the surfaces to be cleaned. Glass, plastics, quartz, porcelain and ferrous metal apparatus can be cleaned safely and effectively in a 2% solution (v/v) of the concentrates or a 0.2% solution (w/v) of the solids. RBS 35 and PCC-54 Cleaners remove both organic and inorganic materials and metal ions from laboratory equipment. The detergents rinse away completely, leaving no residue. Note: We do not sell RBS Products in Europe; EU customers can purchase our PCC-54 Products instead.
