Microbiology and Reusability Validation

Explore everything from reusable device validations, packaging integrity testing and manufacturing support testing to antimicrobial/preservative testing effectiveness, microbial ingress and in-lot release programs.

50+ years of cumulative microbiology experience

In-lot release programs include testing to confirm sterility, the absence of bacterial endotoxin and device bioburden levels

Tailored design for successful global submission

What is microbiology in the medical device industry?

Microbiology testing of medical devices involves identifying the presence and risk of microbial contaminants. If not properly addressed, microbial contamination can cause serious threats to both personal and public health.

When you need to develop an effective microbiological testing strategy, count on our decades of experience. We’ll customize the right microbial assessments for your product that fulfill regulatory requirements. All of our studies are backed by a complete documentation package and are performed with a focus on quality with quick turnaround times.
