MPL GmbH has been the first privately held GMP laboratory with pure dedication to microbial testing. Since its foundation in 1993 MPL has dedicated its activities to the microbial testing of sterile as well as non sterile medicinal products, medical devices and other products, which need to be tested as per pharmacopoeial or ISO-norms. Today, testing of sterile products in a dedicated sterility test Isolator is one of the more recent innovations at MPL.
