These sterile ready-to-use media are filled in autoclavable and break-proof polycarbonate bottles (50 and 250 ml). The composition of the various types of media, comply with the formulations specified in the pertinent standards and regulations. Whereas the liquid media can be used immediately, the agar media first have to be remelted in a water bath at 90 to 100 °C. Once they have cooled down to around 50 °C you can pour agar plates in different sizes and thicknesses to meet your individual demands.

Readybag® gamma-irradiated and pre-weighed granulated media pouches for fast, flexible and easy pathogen testing. Readybag® media pouches speed up and simplify food pathogen testing routines: All media preparation steps are eliminated from workflow. Just add sterile water before incubation. Readybag® series includes Salmonella (Buffered Peptone Water) and Listeria (Half Fraser Broth).

Supplier: Merck

This medium conforms to the ALOA (agar Listeria acc. to Ottaviani and Agosti) medium, a selective medium for the isolation of Listeria monocytogenes in food (AFNOR-validated method). It also enables the testing, sampling and enumeration of Listeria monocytogenes and Listeria spp. in foodstuffs and other source materials. The rich base of the Chromocult® Listeria selective agar encourages excellent growth. The supplement of inhibitors stops most of the bacteria, yeast and fungi from growing. In contrast, Listeria is uninhibited in its growth, producing blue-green colonies; L. monocytogenes also form an opaque halo.
