Microbial Content

Perritt Laboratories performs microbiological method qualification and microbial content and bioburden testing according to methods listed in the United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur. or EP) and Japanese Pharmacopoeia (JP). In addition, we perform testing according to AAMI test methods for medical devices, ASTM testing standards, and other standard testing compendia. We also provide bioburden testing for industrial applications such as building materials, paints and coatings, surfaces and various other applications.

Bioburden testing normally involves enumeration of aerobic, mesophilic bacteria, yeast and molds in everything from raw materials through to finished product. The tests are designed primarily to determine whether a substance or preparation complies with an established specification for microbiological quality such as USP Monographs, compendial specifications or a manufacturers acceptance criteria.

Whether testing to meet United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur. or EP), Japanese Pharmacopoeia (JP) or other compendial requirements, our full-service, cGMP, ISO 17025 accredited microbiological testing services can provide you with timely test results that you require, backed by a staff of dedicated professionals that have been at the forefront of testing since 1973.
