LB media formulations have been an industry standard for the cultivation of Escherichia coli as far back as the 1950s. These media have been widely used in molecular microbiology applications for the preparation of plasmid DNA and recombinant proteins. Vitamins and certain trace elements are provided by yeast extract. Sodium ions for transport and osmotic balance are provided by sodium chloride. Tryptone is used to provide essential amino acids to the growing bacteria. -
LB media formulations have been an industry standard for the cultivation of Escherichia coli as far back as the 1950s.These media have been widely used in molecular microbiology applications for the preparation of plasmid DNA and recombinant proteins. This media has the addition of Kanamycin at 0.05gms/L for use with Kanamycin resistant strains and cells harbouring selection plasmids containing the Kanamycin resistance gene.Peptides and peptones are provided by tryptone. Vitamins and certain trace elements are provided by yeast extract. Sodium ions for transport and osmotic balance are provided by sodium chloride. Tryptone is used to provide essential amino acids to the growing bacteria, while the yeast extract is used to provide a plethora of organic compounds helpful for bacterial growth. -
This is a selective medium primarily for the isolation and differentiation of coliforms and non-lactose fermenting Gram –ve bacterial species from clinical, dairy, industrial and water samples. This media differs from the original MacConkey formulation with the addition of an extra 0.5% Sodium chloride, an altered Bile salt mix and the neutral red concentration was also modified. This enhanced the effect of inhibiting Gram +ve and other non-enteric bacterial species. This medium conforms to the requirements of the Harmonised USP/EP/JP. -
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. -
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 -

The formulation of this medium conforms to the requirements of the United States Pharmacopoeia. Lecithin & Polysorbate 80 (Tween 80) are added to inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds & Tween neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol). NB: Final sterilisation of this medium is by Gamma irradiation and it is triple wrapped. Dose Range: Min: 8.0kGy Max: 15.0kGy

Sabouraud Dextrose Agar with Lecithin, Tween 80, Histidine & Sodium Thiosulphate (VHP) (USP) - Irradiated 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. Lecithin, Polysorbate 80 (Tween 80), 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 inactivate mercurials). 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

This is a differential medium for the isolation of Escherichia coli 0157:H7. It differs from other MacConkey media in that lactose has been replaced by sorbitol. As Escherichia coli 0157:H7 does not ferment sorbitol, it produces pale translucent colonies whereas most other strains of Escherichia coli do ferment sorbitol and produce pink colonies. -
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 -
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). 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 -
