Pharmaceutical Culture Media
Microbiology media for cleanroom environmental monitoring and sterility testing, made for the pharmaceutical industry in Germany. Available across the UAE, Saudi Arabia and Egypt.
What environmental monitoring media have to do
Aseptic manufacturing relies on an environmental monitoring programme to show that classified areas stay under control. Settle plates, contact plates, active air sampling and glove prints sample the air, surfaces and people, and EU GMP Annex 1 sets expectations for each cleanroom grade.
The media carry that programme. They must recover low numbers of organisms that may be stressed by disinfectants or drying, stay usable through the exposure time, and neutralise disinfectant residues picked up from surfaces. Plates taken into the most critical areas must themselves be sterile and packaged so they can be transferred in without bringing contamination with them.
Sterility testing has its own media requirements, set out in the pharmacopoeias. Every batch of media is expected to pass growth promotion testing, so its quality is as important to the result as the test itself.
Media made for pharmaceutical microbiology
PMM — Pharmamedia Dr. Müller GmbH — focuses on culture media for the pharmaceutical industry. It was founded in 2013 by Dr. Rolf Müller, who had previously founded and directed heipha Dr. Müller GmbH from 1973 for over 30 years.
PMM’s production facility in Leimen, near Heidelberg, Germany, was built and equipped to the requirements of pharmaceutical customers manufacturing sterile drugs. Its core offering is microbiology media for environmental monitoring and for sterility testing.
Arab Lab supplies PMM media to manufacturers and QC laboratories across the region, alongside the rapid sterility testing and isolator equipment that often sits in the same laboratory. See rapid sterility testing.

Frequently asked questions
Which media are used for cleanroom environmental monitoring?
A general-purpose medium, typically soybean-casein digest agar with neutralisers, for settle plates, contact plates and air sampling, with additional media where the programme targets fungi.
Why do contact plates contain neutralisers?
Surfaces carry disinfectant residues that would stop organisms growing on the plate. Neutralisers inactivate those residues so contamination is recovered.
Why are some plates irradiated and multi-wrapped?
Plates taken into Grade A and B areas must be sterile on the outside as well as the inside. Irradiation and layered packaging let them be transferred into aseptic areas without introducing contamination.
What is growth promotion testing?
A check that each batch of media supports the growth of specified test organisms, so a negative result can be trusted.
