This is a general-purpose complex medium for the cultivation and isolation of aerobic and anaerobic microorganisms. The base medium, Tryptone Soya Agar (Soybean-Casein Digest agar), conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EP), and Japanese Pharmacopoeia (JP). Histidine and Sodium Thiosulphate are added to inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds, Tween 80 and Histidine neutralises phenols, formalin, hexachlorophene and, in combination with the Lecithin, ethanol and Sodium Thiosulphate inactivates mercurials, halogens and aldehydes). The medium can be incubated under aerobic or anaerobic conditions for sterility testing, air sampling and other areas of bacteriological investigation. This product is wrapped in barrier film to allow for use in Vaporised Hydrogen peroxide sterilisation systems. This particular product is triple wrapped and terminally sterilised by Gamma irradiation. Dose Range: 8.0 kGy – 15.0kGy
