Instructions For Use
Description
Tryptic Soy Agar (TSA), also known as Casein Soya Bean Digest Agar, is a non selective isolation medium used for the enumeration of bacteria and fungi from different materials, for environmental and personnel hygiene monitoring and for the preparation of reference strains with the aim of growth promotion tests of culture media. This medium complies with the recommendations of the current United States (USP), European (EP) and Japanese Pharmacopoeia (JP) for the microbiological examination of non sterile products. The medium is also available as triple-wrapped irradiated (9-20 kGy) plates, particularly suitable for use in restricted areas like isolators and clean rooms.
