Presumptively identify coliform organisms in milk, water and foods as specified by the American Public Health Association with Thermo Scientific™ Oxoid™ Lactose Broth (Dehydrated). Beef extracts and peptone in this liquid medium supply essential nutrients while lactose is a fermentable carbohydrate for coliforms. Coliforms ferment lactose in the medium resulting in gas formation which is indicative of positive results.

Cleaver Scientific
Available in single and dual wavelength formats, in 21x21cm and 21x26cm sizes, our transilluminators are supplied either as standalone units or with the microDOC, as part of a fully integrated gel documentation system. With a large surface area, each transilluminator serves as the perfect workstation for viewing and working with fluorescently-stained protein and nucleic acid gels.
Standard features include a high/low intensity safety switch and an efficient starter that allows each of the six 8-Watt UV tubes to energise quickly without flickering, while special filter glass minimises unwanted background light. All of these features maximise contrast and sensitivity, allowing even the faintest fluorescent gels to be viewed. Two dual wavelength models offer added flexibility and convenience.
