• This is a general-purpose complex medium for cultivation and isolation of fastidious bacteria, yeasts and moulds. The formulation is based on the United States Pharmacopoeia (USP Medium II) and European Pharmacopoeia (EP Medium B). Lecithin and Polysorbate 80 (Tween 80) are added to inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol). 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

  • Violet Red Bile Glucose Agar (VRGBA) (USP) Violet Red Bile Glucose Agar is a selective medium for the isolation and enumeration of Enterobacteriaceae in food products. It is a modification of the original Violet Red Bile Agar (PP1150) with the Lactose being replaced with Glucose and conforms to the requirements of the Harmonised USP/EP/JP. As all Enterobacteriaceae ferment glucose it allows for a wider range of organisms to be detected. The medium is made selective by the inclusion of Bile Salts and Crystal Violet to inhibit gram-positive and other non-enteric organisms.

  • 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

  • R2A medium was developed to determine the bacterial count including heterotrophic bacteria in potable waters during treatment and distribution. This medium has a low nutritional content and therefore requires extended incubation times. It is recommended by the Environmental Agency, Methods for the Examination of Waters and Associated Materials, and Standard Methods for the Enumeration of Water and Wastewater.

  • This is a selective medium for the isolation of yeasts and fungi and is particularly suitable for use in sterility testing. The low pH (5.6) of the medium is inhibitory to most bacteria and many diagnostic features such as spores and pigmentation are well developed on this medium. The formulation of this medium conforms to the requirements of the United States Pharmacopoeia & European Pharmacopoeia. This product is wrapped in barrier film to allow for use in Vaporised Hydrogen peroxide sterilisation systems. NB: Final sterilisation of this medium is by Gamma irradiation and it is triple wrapped. Dose Range: Min: 8.0kGy Max: 15.0kGy

  • Tryptone Soy Agar is a nutritious general-purpose medium supporting a wide range of organisms, this formulation has been modified by the addition of Tween 80 (Polysorbate 80) and Lecithin. It is recommended for use in environmental testing, particularly in areas subjected to surface disinfection, and conforms to the requirements of the British Pharmacopoeia for sterility testing of appropriate pharmaceutical products. Lecithin and Polysorbate 80 (Tween 80) inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol).

  • Dey & Engley Agar has the ability to neutralise antimicrobial chemicals and is used for environmental sampling for the detection and enumeration of microorganisms present on the surface of sanitary importance. In this formulation the agar has been modified by the addition of Tween 80 (Polysorbate 80) and Lecithin. It is recommended for use in environmental testing, particularly in areas subjected to surface disinfection, and conforms to the requirements of the British Pharmacopeia for sterility testing of appropriate pharmaceutical products. Lecithin and Polysorbate 80 (Tween 80) inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol).
