Contrad 70, Decontamination Liquid
Biodegradeable, Phosphate Free
Contrad 70 is a biodegradable concentrate combining anionic and non-anionic surface active agents with stabilizing agents, alkalis and non-phosphate detergent builders, to produce a highly effective cleaning compound.
Contrad 70 is more efficient than chromic acid mixtures and has none of the risks associated with the storage, handling and disposal of virulent acids. Cantrad 70 is also a highly effective radioactive decontaminant due to the potent surface activity. Strontium 90, Iodine 131, Carbon 14, Phosphorus 32, Au 198, Hg 203, Transplutoniuim, Tantalum and radiocarbon are all handled by Contrad 70. It also caters for a wide range of problem contaminants including: abrasives, agar, algae, bacterial, blood, distillations residues, latex, protein complexes, tar, silicone, grease and oil, reagents, etc. Contrad 70 is easy to use. It is non toxic, non acidic, not flammable and does not release any harmful odors or vapors. It thoroughly removes the dirt from glassware, ceramics, rubbers, plastics, stainless steel and ferrous metals. Contrad 70 can usually be diluted with tap water but in special applications such as in medicine or pharmacology, the use of demineralized water is recommended.
The cleaning can be intensified by vortexing, increasing concentration, or applying sonication. Contrad 70 is stable up to 90°C without the generation of dangerous vapors. For decontamination, a 5% solution should be used. For hard to remove radioactive contaminants, we recommend a 20% solution.
