Tryptic Soy Agar - Ready-to-use Contact Plates

Tryptic Soy Agar (TSA, Soybean Casein Digest Agar) is a complex medium for cultivation and isolation of a wide range of bacteria, yeasts and molds. The media finds its application in environmental monitoring by determining the total microbial aerobic count on dry, sanitized surfaces and personnel in Isolators and Clean Rooms.

Tryptic Soy Contact Agar with Cephase + LT – ICR+ is designed for the determination of the total microbial aerobic and anaerobic count on dry, sanitized surfaces and personnel in Clean rooms and Isolators. It is a complex medium for cultivation and isolation of a wide range of bacteria, yeasts and molds. 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. The medium contains Cephase to inactivate a broad range of beta lactam-antibiotics and is supplemented with the two neutralizers lecithin and polysorbate (Tween^®) 80, to inactivate possible residues of disinfectants on dry surfaces. In addition, the ICRplus (plus or “+”) plates are supplied with a lockable lid for safe transport after sampling without the risk of losing the lid. ICRplus plates are suitable for aerobic and anaerobic incubation by turning the lid into the close position for aerobic incubation and into the vent position for anaerobic incubation
