Why choose Microbio Analytical

Microbio Analytical was founded by industry professionals with deep experience supporting pharmaceutical, biotechnology, and medical device manufacturers, built specifically to handle the programs that don’t fit a standard testing model.

Our team has supported hundreds of testing programs across regulated industries, including outsourced programs with tight timelines, difficult matrices, and direct regulatory scrutiny. Clients come to us for investigations, deviation support, and method troubleshooting, not just routine testing. When something isn’t working, we’re built to diagnose it.

We operate as part of the CS Analytical laboratory network, giving clients access to integrated testing capabilities across microbiology, gas testing, materials testing, packaging, biocompatibility, and container closure integrity — without managing multiple vendors.

We work with teams across:

Pharmaceutical · Biotechnology · Medical Device · Combination Products · Packaging & Components · CMOs
