TAT Broth


Liquid culture medium for detection of microorganisms from highly viscous or gelatinous materials.

TAT (Tryptone-Azolectin-Tween) Broth is a liquid medium used for the microbiological examination of cosmetics and topical drugs, particularly from highly viscous or gelatinous materials.

This medium, also known as Fluid Casein Digest – Soy Lecithin – Polysorbate 20 Medium (SCDLP 20 Broth), complies with ISO 21149 for detection of aerobic mesophilic bacteria. Enzymatic digest of casein provides nitrogen, vitamins, minerals and amino acids essential for growth. Lecithin and polysorbate 20 neutralize preservatives in pharmaceutical products.

Quanti-CultiControl


for growth promotion testing of culture media

The Quanti-CultiControl are lyophilized, quantitative microorganism preparations to be used in industrial laboratories for Quality Control purposes. Processed as directed, these preparations provide a challenge of <100 CFU per 0.1 mL, which is a concentration usually suitable for several pharmaceutical applications, including growth promotion testing of culture media to be employed in sterility testing. These microorganism preparations are derived from the American Type Culture Collection (ATCC®).


The Quanti-CultiControl are suitable for the Growth Promotion Test recommended by the international Pharmacopoeiae, without need of intermediate dilution steps, since each rehydrated suspension generates less than 100 UFC for 0.1 mL inoculum. Each suspension (1 mL) allows 10 inocula.
