  • A general-purpose diluent for the preparation of test samples according to ISO/DIS 6887-5.
  • This is one of the large group of media, affectionately known as ‘Peptone Water Sugars’, that are generally used in the screening and/or identification of organisms particularly the enterobacteriacae. A positive fermentation of the substrate is clearly indicated by the medium turning pink due to the inclusion Andrade’s Indicator.
  • A standard biochemical reagent suitable for a variety of uses, primarily the preparation of serial dilutions.
  • Based on the formulation of Dulbecco Solution ‘A’ this balanced salt solution is intended for use primarily in Tissue Culture techniques. It can be used either on its own or with the addition of Calcium and Magnesium salts (Dulbecco Solution B).
  • Based on the formulation of Dulbecco Solution ‘A’ this balanced salt solution with added Tween is intended for use primarily in Tissue Culture techniques. It can be used either on its own or with the addition of Calcium and Magnesium salts (Dulbecco Solution B).
  • 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.
  • Rappaport Vassiliadis (R.V.) Single Component Enrichment Broth This is an alternative to Selenite and Tetrathionate broths, as a selective enrichment broth for the isolation of Salmonellae spp from food, dairy and environmental samples and is claimed by some workers to be superior to both these formulations. It can also be used in clinical bacteriology but care must be taken to ensure that only a light inoculum is used. Malachite Green and Magnesium Chloride are included in the formulation as selective agents due to their ability to inhibit most enteric organisms but allow salmonellae to multiply freely. NB: This media is not recommended for use when salmonella typhi is suspected.
  • This is a selective enrichment broth for the isolation of Salmonella spp. from pharmaceutical, food, dairy and environmental samples. Malachite Green and Magnesium Chloride are included in the formulation as selective agents due to their ability to inhibit most enteric organisms whilst allowing Salmonella spp. to multiply freely. Gram +ve bacteria and most other enteric bacteria, are typically susceptible to or inhibited by Malachite Green, the high osmotic pressure and/or the low pH of the medium. It should be noted that S.typhi and S.choleraesuis are sensitive to Malachite Green and may therefore be inhibited. This medium conforms to the requirements of the Harmonised USP/EP/JP.
  • An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method.
  • An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method.
  • Saline (0.45%) is suitable for use in preparation of food samples and/or as a rinse fluid during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory.
  • Saline (0.85%) is suitable for use in preparation of food samples and/or as a rinse fluid during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory.
  • BM0381

    Saline (0.9%)

    Saline (0.9%) is suitable for use in preparation of food samples and/or as a rinse fluid during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory.
  • A medium for the selective enrichment of Salmonellae spp from both clinical and food samples. It is a buffered Lactose Peptone Broth to which Sodium Biselenite is added as the selective agent and Cystine to enhance the recovery of salmonella in low numbers. Subcultures should be made from the top 1/3 of the broth after not more than 24 hours incubation as after this time there is a loss of selectivity.
  • BM0360 Selenite F Broth is a medium for the selective enrichment of Salmonella spp. from both clinical and food samples. Following overnight incubation subculture(s) are usually made on to one or more of the many selective enteric solid media. Selenite F Broth is also recommended by the American Public Health Association (APHA) for the examination of food. Subcultures should be made from the top 1/3 of the broth after not more than 24 hours incubation as after this time there is a loss of selectivity.
  • 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).
