Microbial limits USP 61
The microbial limits test includes a standard plate count for total aerobic bacteria and molds and yeasts. In addition a screening is performed for the presence of Staphylococcus aureus, Pseudomonas aeruginosa, Pseudomonas cepacia, Escherichia coli, and Salmonella sp. The microbial limits test may be modified for specific testing needs.
Antimicrobial Preservative Efficacy USP 51, EP, BP, CTFA
USP 81 antibiotic potency assay USP 81, USP 28
Plate Counts USP 28
The standard plate count procedure provides a standardized mean of determining the density of heterotrophic bacteria in samples. This is an empirical measurement because organisms occur singly, in pairs, clusters, or packets, and no single growth medium or set of physical and chemical conditions can satisfy the physiological requirements of all organisms in a sample.
