Many products in this space may have antimicrobial properties, and we know how to neutralize them during testing for accurate results.
Microbial content testing measures viable organism counts and protects the health of your consumers as well as your product from foul odors, premature spoilage, recalls, shortened shelf life, and compliance failures caused by objectionable microorganisms.
This test must be performed under highly controlled conditions, which is why global companies turn to Perritt Laboratories for accurate, defensible data. Our FDA-registered, cGMP-compliant, and ISO 17025:2017 laboratory and more than 50 years of experience in testing, means you receive reliable results that regulators trust, including results that meet ASTM, PCPC, and other standard testing compendia.
Microbial content is typically assessed through bioburden and microbial limit tests.
Bioburden testing performed on an unsterilized product determines the types and numbers of microorganisms present in a batch or product. After microbiologists ensure the testing method is valid, verify that the agar can support microbial growth for a microbial content test, and perform other checks, they incubate plates so they can count the microorganisms.
A microbial limit test quantifies microbial load (total count) and the presence of objectionable organisms (specific pathogens) against regulatory or compendial standards.
We offer finished product testing to provide documentation about the safety of your products and raw material testing to help you evaluate whether specific ingredients are high-risk for your formulations. Our laboratory also offers:
Our team works collaboratively with the following industries:
Many products in this space may have antimicrobial properties, and we know how to neutralize them during testing for accurate results.
Our team identifies viable microorganisms that could interfere with the performance of paints, building materials, coatings, and other products.
We test for objectionable microorganisms that could result in an FDA warning letter, product deterioration, or consumer harm.
Whether you are creating cleaners, baby products, or other products, we can test raw materials, formulations, and other components that come into contact with your product.
Packaging for nonsterile pharmaceuticals and related products is often required to control or limit microbial contamination and, in some cases, must meet specified bioburden limits.
At Perritt Laboratories, our microbial content and bioburden testing and microbiological method qualification come with robust documentation and a collaborative approach to provide you with defensible, actionable data. Contact our team today to review your testing needs.
