MLT Harmonized Products
Dilution Bottles

We offer media and QC organisms specific for the new harmonized microbial limits testing (MLT). Pharmaceutical products, both registered and new, fall under these harmonized guidelines. Facilities manufacturing these products must have quality control teams validate that the pharmaceuticals pass the new testing guidelines (both enumeration and absence of specified organisms), by incorporating these new methods, including the appropriate culture media, into their QC processes.

Our MLT offering provides pharmaceutical and biotech customers all of the products needed for use in validating their products, raw materials, and quality control processes.
