Sterility Culture Media
Merck offers the following sterility culture media:
Soybean-Casein Digest Medium (Trypcase Soy Broth)
The Soybean-Casein Digest Medium, also known as Trypcase Soy Broth, is suitable for the culture of both fungi and aerobic bacteria. This medium is used for sterility testing by membrane filtration or by direct inoculation. It is also used as pre-enrichment broth for non sterile products. Compliant to the USP, EP and JP.
Fluid Thioglycollate Medium
Fluid Thioglycollate Medium (FTM) is primarily intended for the detection of anaerobic bacteria. However, it also enables aerobic bacterial detection. This medium is used for sterility testing by membrane filtration or direct inoculation as described in the USP, EP and JP.
Clear Thioglycollate Medium
Clear Thioglycollate Medium has the same growth promotion properties as the standard FTM and is compliant to the USP, EP and JP. The alternative formulation brings extra visual clarity versus the FTM which has a slight turbidity or haze. A high visual clarity medium is preferred by many users, when compared with the hazy or opalescent appearance of FTM.
