Maximum Recovery Diluent (Peptone/ Saline Diluent) An osmotically controlled solution for the preparations of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The presence of a low level peptone lessens the physiological shock normally experienced by bacterial cells when they are introduced to a diluent such as Ringers Solution. The level of peptone is such that multiplication of the organisms is not possible in the time in which the sample will be present in the diluent. -
Glucose agar allows for the detection of glucose fermentation (with or without gas production) as an identification test for Enterobacteriaceae (ISO 21528) and B.cereus (ISO 7932). It is further enriched by the addition of Yeast Extract. Bromocresol Purple is also included and acts as an indicator of glucose fermentation. -
Lactose Broth is frequently used as a pre-enrichment medium when testing foods, water samples and dairy products for Salmonella spp. In dried or processed foods, Salmonella species may be sublethally injured and present in low numbers. Pre-enrichment in a nonselective medium such as Lactose Broth allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella spp. over other bacteria.
This buffer is intended primarily for use as a neutralising agent following treatment with alkaline compounds during the decontamination and homogenisation process of Sputum specimens prior to inoculation onto appropriate culture media for the isolation of Mycobacterium spp.
This is an aqueous solution of Sodium Hydroxide (2%) with Phenol Red Indicator suitable for use in the digestion of Sputum samples prior to culture of the samples for Mycobacterium spp. It is generally used in conjunction with Sputum Neutralising Buffer (BM1324).
This is a sterile aqueous solution of Potassium Di-Hydrogen Ortho-phosphate (16.0 % w/v) suitable for use in the neutralisation following the digestion of Sputum with Sodium Hydroxide prior to culture. It is generally used in conjunction with Sodium Hydroxide 4% with Phenol Red Indicator 0.2%.
This is a sterile aqueous solution of Potassium di-hydrogen phosphate (16.0 % w/v) with Phenol Red Indicator suitable for use in the neutralisation following the digestion of sputum with Sodium hydroxide prior to culture. It is generally used in conjunction with BM1322 Sodium hydroxide 4%.
A low pH medium for the growth of yeasts and moulds. This broth is also used as part of sterility testing protocols for various products. The high carbohydrate content of the medium ensures rapid growth of yeasts and moulds.
One of two media usually used as a pair, the other being Kohn’s No 2 (BM2120), to differentiate members of the enterobacteriacae. Kohn’s No 1 contains Mannitol and Dextrose as substrates and Phenol Red as the indicator. To inoculate the medium, smear the inoculum onto the surface of the slope and also stab it deep into the butt. After incubation the production of acid by both substrates is shown by the medium turning yellow. If fermentation is of Dextrose only the butt will have become yellow and the surface red, while if only Mannitol is fermented the slope will turn yellow. The production of gas is demonstrated by the appearance of bubbles within the medium. Urease positive organisms turn the medium bright pink. For details of the many reactions that may arise during the use of this medium reference should be made to one of the many standard textbooks.
Modified Letheen Broth intended for use in the isolation of microorganisms from cosmetics. Total neutralisation of disinfectants is critical as disinfectant residues can result in a false negative result. Sodium bi-sulphite, Lecithin and Polysorbate 80 (Tween 80) inactivate quaternary ammonium compounds. Tween 80 neutralises phenols, formalin, hexachlorophene and, in combination with the Lecithin, ethanol.
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

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).
