  • 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).The medium can be incubated under aerobic or anaerobic conditions for sterility testing, air sampling and other areas of bacteriological investigation. This particular product is triple wrapped and terminally sterilised by Gamma irradiation. Dose Range: 8.0 kGy - 15.0kGy
    Details
  • A selective medium for the isolation of Staphylococcus aureus. The high level of Sodium Chloride inhibits most other organisms and as most Staphylococcus aureus ferment Mannitol the inclusion of Phenol Red indicator gives rise to yellow colonies. This formulation complies with the requirements of the Harmonised USP/EP/JP. NB: Some strains of coagulase negative staphylococci can give rise to false positive results on this medium It is necessary therefore to confirm the identity of Staphylococcus aureus by other confirmatory tests (e.g. Coagulase test, Latex test etc.)

  • Plate Count Agar (APHA) (Standard Methods Agar, Tryptone Glucose Yeast Agar) This medium is formulated to A.P.H.A. specification and intended for use in food, dairy and water bacteriology to perform Total Viable Counts. The agar is of high gel strength and is therefore suitable for use in pour plate techniques as well as surface inoculation.
    Details
  • This medium is recommended for the detection and enumeration of yeasts and moulds in food and dairy products. It can also be used for the cultivation of fungi although with the prolonged incubation necessary cultures may become overgrown by bacteria. The low pH (5.6) suppresses the growth of most bacteria and the low mineral content ensures good pigment production by fungi where appropriate.
    Details
  • 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.
    Details
  • 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.
    Details
  • 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).
    Details
  • 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).
