TSA Letheen Agar 500 grams/bottle

Login For Price
TSA Letheen Agar is a highly nutritious agar and it is recommended for use in the microbiological testing of cosmetics. It can be used to inactivate quarternary ammonium compounds and other preservatives when establishing the number of bacteria present in cosmetics and other materials. Pancreatic digest of casein and papainic digest of soy bean provide nitrogen, vitamins, minerals and amino acids essential for growth. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Lecithin and Tween 80 neutralize quaternary ammonium compounds and partially neutralize the preservative system commonly found in cosmetics. Bacteriological agar is the solidifying agent. The medium is also used for microbiological samples from surfaces that have been treated with disinfectants.
