Description

General description

Tryptic Soy Contact Agar + LTH - RT+ is designed for the determination of the total aerobic and anaerobic microbial count on dry, sanitized surfaces and personnel in the non-critical area.
TSA medium is used for the cultivation and isolation of a wide range of bacteria, yeasts, and molds. The formulation contains a 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 neutralizers such as lecithin, polysorbate (Tween^®) 80, and histidine to inactivate disinfectant residues. Additionally, the plate model (plus or “+”) is supplied with a lockable lid for safe transport after sampling and also for aerobic and anaerobic incubation of the plates.

Application

The TSA Contact is designed for the determination of the total aerobic and anaerobic microbial count on dry, sanitized surfaces and personnel in the non-critical area.
