CG Pharma Production
Chemistry in the cleanroom.
Production in the Grade C & D cleanroom according to §13 of the German Medicinal Products Act (AMG) under GMP conditions.
In our cleanroom production, we rely on perfect interaction between technology and people. The production of pharmaceutical media uses technical equipment that meets the highest standards.
Production under cleanroom conditions
Grade C and D.
Filling, decanting, dilution, mixing – our production under Grade C and D cleanroom conditions makes us a specialised partner to the pharmaceutical industry.
We offer the service of this production at the Laatzen site. We are one of the few companies that can also handle hazardous substances in the cleanroom and produce innovative, flexible solutions for our customers in the pharmaceutical industry. We are geared towards the pharmaceutical needs of tomorrow and offer solutions for the pharmaceutical, biotech and medical device industries according to individual specifications.

We are a classic contract manufacturing organisation. Manufacturing takes place in a GMP-certified environment. Depending on the medium to be manufactured, batch sizes of up to 5,000 litres can be produced in stainless steel or PVDF batch tanks.
Validated manufacturing processes enable homogeneous and reproducible quality for each individual batch produced.
Mixing, processing and repackaging of liquid and solid materials, container capacity up to 5,000 litres per batch (stainless steel/PVDF), and manufacture of standard and customer-specific buffers for upstream and downstream applications.
With our individual packaging concepts, we offer solutions for transport that are both innovative and sustainable.
