Environmental Testing Services
Microtest is acknowledged as an industry leader in specialized environmental testing services. Our environmental testing laboratories can swiftly and accurately determine viable microbial and nonviable particulate levels of any area used for medical device and pharmaceutical cleanroom or manufacturing purposes. Our experts also perform certifications for all controlled environments, including cleanrooms, biological safety cabinets, laminar flow hoods, isolators and fume hoods.
Our environmental testing laboratories offer both onsite and remote services.
For onsite work, Microtest specialists perform environmental microbiology sampling of water, disinfectants, surfaces, air, and compressed air/gases right at the customer location. We also provide particulate sampling of nonviable air and compressed air/gases as well as sampling for an array of different contaminants and the levels of each; i.e., oils, carbon monoxide, H20.
For remote environmental monitoring, Microtest supplies sampling plates and sterile water collecting vials — everything needed for customers to collect samples in their own cleanrooms or manufacturing spaces. We also furnish full instructions for receipt, sampling, storage, and return to Microtest. Once environmental testing samples are received at our laboratory, we perform full incubation, analysis, traceability/control record keeping, and reporting procedures required by regulatory authorities.
Both testing regimens utilize SDA media, with or without neutralizers, for recovering environmental yeast and mold contaminants. TSA media is used to recover any aerobic or facultative anaerobic bacteria. RODAC plates help monitor surface and air contamination. Settling plates are utilized for remote viable air monitoring while PBI SAS microbial air samplers are used during onsite monitoring. Laser particle counters detect non-viable airborne particulates at sizes between 0.3 µm and 10.0 µm.
Experienced Microtest regulatory microbiologists perform all environmental testing services.
