Thermo Scientific RBS 35 Detergent Concentrate is a general cleaning agent for use on many laboratory surface materials and glassware, including lenses, mirrors, and reflectors.

Applications include the removal of:

• Coomassie blue dye from test tubes and quartz cuvettes
• Blood or serum residue from glass or plastic beakers and flasks
• Colored dyes from porcelain mortar and pestles
• HIV virus from glassware, tabletops and flooring
• Radioactive isotopes from benchtops and instrument surfaces

The cleaning detergent is a mixture of anionic and nonionic surfactants. RBS™ 35 Detergent 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 a 2% (v/v) solution for routine washing applications or soaking in a warm 20% solution to free particularly stubborn dry residues. Mix two parts 2% RBS Detergent solution with one part ethyl alcohol to remove greases and oils.

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.

We do not sell RBS Products in Europe; EU customers can purchase our PCC-54 Products instead.
