Detection of Microorganisms in Isolators & Cleanrooms

Merck Millipore’s Heipha ICR Plus Neutralizer A contact plates improve detection of microorganisms on disinfected surfaces in isolators and cleanrooms.

They allow the detection of microorganisms in the presence of many disinfectants, including those which often cannot be sufficiently inactivated by other neutralizers, such as polysorbate 80, lecithin, histidine and thiosulfate. The medium in the plates is supplemented with a mixture of ingredients called Neutralizer A to inactivate residues of a broad range of disinfectants including polyhexamethylene biguanides and quaternary ammonium compounds.

The basic medium complies with the formulation of casein soya bean digest agar according to the recommendation of the current European, Japanese and United States Pharmacopoeia.
