Contrad 70 is an emulsion of anionic and nonionic surfactants in an alkaline aqueous base. It removes virtually any contaminant from every surface – even silicones, dried proteins, carbon, most resins, waxes, and oils. Contrad 70 works by soaking, scrubbing, or in ultrasonic cleaning baths. It is totally rinsable eliminating detergent build-up that interferes with analysis, tissue culture, and other critical procedures. Extremely effective when used as an ambient soak solution – no need to scrub!
