TSA 90MM ICR+

Tryptic Soy Agar 90mm ICR+ settle plates (lockable) is designed for the enumeration of the total aerobic microbial count in air via active or passive air monitoring as well as fingerprints of personnel in isolators and clean rooms.. It is a general-purpose medium that supports the growth of non-fastidious as well as moderately fastidious microorganisms. The formulation of the Soybean Casein-Digest medium contains combination of casein and soy peptones supplying organic nitrogen, particularly amino acids and longer-chained peptides. Sodium chloride maintains the osmotic equilibrium and the medium is supplemented with pyruvate to provide an efficient neutralization of residues of hydrogen peroxide. In addition, the plate model (plus or "+") is supplied with a lockable lid for safe transport after sampling without the risk of losing the lid. For aerobic incubation the plates should be locked in the "CLOSED"-position (turn the lid clockwise) and for anaerobic or microaerophilic incubation in the "VENT" position (turn the lid anti-clockwise)
