A general purpose broth suitable for the cultivation of most micro-organisms including many fastidious organisms and fungi. It is recommended by the United States Pharmacopoeia for sterility testing of many pharmaceutical products. -
Tryptone Water is an alternative medium to Peptone Water and more reliable for the testing of Indole production. The medium has a high content of Tryptophan that many organisms, particularly coliforms, break down to form Indole. After incubation add a few drops of Indole reagent to determine the Indole reaction (Red colour is Positive). -
Recent developments in culture media have given rise to the use of chromogenic substrates as a means of differentiating bacteria particularly among the coliform group of organisms. This is one such medium and has been developed primarily as a selective medium for the isolation and enumeration of Escherichia coli in food samples. Based on Tryptone Bile Agar it incorporates the chromogenic agent X-glucuronide, which detects glucuronidase activity, the same enzyme as is detected by MUG reagent. Escherichia coli can be differentiated from other coliform organisms by the presence of glucuronidase resulting in the colonies being blue/green while the other coliforms are colourless. For information on the full technical detail as to the functionality of this medium reference should be made to the many publications available. -
The Viral Collection Kit is intended to be used to collect specimens suspected of containing virus and to preserve active virus during transport to a laboratory for analysis (1). The kit consists of a sterile swab for specimen collection from most body areas* and Virus Transport Medium (VTM) for the transportation of viral samples from the patient to the diagnostic laboratory. The stability of viral specimens afforded by the product formulation enables specimen transport and subsequent storage in the 2-30°C range for up to 72 hours before starting analysis. Virus Transport Medium: The inclusion of Hanks balanced salt solution produces an isotonic medium with buffering capacity to maintain pH, provides essential mineral salts, and a visual pH indicator. HEPES provides additional pH stability and bovine serum albumin is present to help stabilise virus particles. Gentamicin and amphotericin B are added to prevent growth of unwanted bacteria and fungi that may be present in the specimen. 1. Clinical and Laboratory Standards Institute (CLSI), 2014.

BM1673 Virus Transport Medium (VTM) is a balanced medium for the transportation of viral samples (with or without a swab). The inclusion of Hanks balanced salt solution produces an isotonic medium with buffer capacity to maintain pH, provide essential mineral salts, and a visual pH indicator. Bovine serum albumin is present to help stabilise virus particles. Gentamicin & amphotericin B are added to prevent growth of bacteria and fungi that may be present in the specimen. • 3ml in self-standing M043 Tube • Aseptically filled • Red cap with swab capture point • Non-hazardous • Storage: 2-25°C • Shelf life: 365 days • Diagnostic processing should commence within 72hrs of sample collection. Medium is suitable for analysis via molecular (eg PCR), cell culture and immunofluorescence testing procedures.
