Buffered Peptone Water Broth is used as a diluent or for non selective enrichment of microorganisms such as Salmonella species or E. coli from foods and environmental samples prior to selective enrichment and isolation. Microorganisms that may be present in a food product can be sub-lethally injured by food processing techniques and may not be recovered by direct selection techniques. Buffered Peptone Water Broth promotes the recovery of those microorganisms that may be injured.

The body and cap of our Detectawipe Drywipe Marker are moulded from high-density polyethylene, containing a non-toxic metal detectable additive. This compound can be detected by correctly calibrated in-line metal detection systems. The Detectawipe features Drywipe ink suitable for use on whiteboards and other glossy surfaces that can be wiped clean with a cloth or tissue.

Available in blue, black, red, and green ink in bullet nib with a multi coloured pack also available.

Blue and black ink are available in the fine tip nib.

Lauryl Tryptose (LST) Broth is used for the detection of coliform bacteria in water and wastewater. Lauryl Tryptose Broth is not intended for use in the diagnosis of disease or other conditions in humans. Lauryl Tryptose Broth is a selective medium for the detection of coliforms in water, dairy products and other foods. The American Public Health Authority (APHA) recommend Lauryl Tryptose Broth for the Most Probable Number Presumptive Test of coliforms in waters, effluent or sewage and as a confirmation test of lactose fermentation with gas production from milk samples and for the detection of coliforms in foods. Lauryl Tryptose Broth is prepared according to the formulation of Mallmann and Darby. Mallmann and Darby showed that tryptose at a concentration of 2% increased the early logarithmic growth phase when compared to meat peptone.

These researchers added phosphate buffers and sodium chloride, which improved gas production by "slow lactose fermenting" organisms. Sodium lauryl sulfate was incorporated as a selective agent for the inhibition of non-coliform organisms. This medium can also be used with the addition of MUG (4- methylumbelliferyl-β-D-glucuronide) according to the ISO Standard 11866-2 to give enhanced detection of Escherichia coli.
