The pharmaceutical industry traditionally has particular high quality standards. We reliably support our customers from the pharmaceutical industry in achieving these goals.

GfPS is GMP certified. The GMP document (certificate) certifies that we, as a pharmaceutical testing laboratory in the sense of § 14 (4) of the German Medicines Act (AMG), are permitted to carry out microbiological quality control tests, particularly sterility testing and endotoxin tests, and fulfil the requirements of the EC Guide to Good Manufacturing Practice for Medicinal Products.


Medical devices require standards that are similarly high to those for pharmaceuticals. We support you in product analysis as well as in planning, testing and optimisation of your production conditions.

The range of medical products and devices is extremely varied, ranging from contact lens care products and bandages to dialysis machines and catheters.

Due to the accreditation at DAkkS (certificate) according to DIN EN ISO/IEC 17025, Directives 93/42/EEC and 90/385/EEC in the areas of microbiological-hygienic testing of medical devices including sterilisation procedures and environment monitoring, the tests carried out by GfPS in this area are recognized for conformity assessment throughout Europe.


The requirements for the production of cosmetics have increased enormously: On the one hand, consumers expect first-class products of consistently high quality, and on the other hand legislature requires GMP conditions in production. We advise our customers in the cosmetics industry as an experienced, competent partner. Our common goal: efficient production processes and high-quality end products.


In the area of hygiene in hospitals and medical practices GfPS mbH provides monitoring of environmental conditions. Additionally, the equipment for sterilisation and disinfection can also be inspected. From the shipment of biological indicators and advice on local use to the evaluation of the appropriate test systems – GfPS is at your side to advise you.


Our analytical services include efficacy studies of detergents and cleaning products for various uses (clinical, food, industrial, domestic, public facilities, etc.) as well as microbiological testing of disinfection machinery and cycles and micro-biological wash-cycle monitoring.


Modern functional textiles must deliver maximum performance. We check the effectiveness of your products and determine the hygiene-relevant parameters. With modern textile analysis, we support you with the quality assurance of your production, e. g. the determination of microbial contamination (bioburden) of textiles with an exceptionally high requirement for low microbial count


There are several aspects of environmental analysis that are generally summarised in the term “environment”. These include the analysis of wastewater samples as well as the identification of species in the domain of mould analysis. Our years of experience and the annual training of our professionals in this area ensure our continued expertise and the high quality of your analysis results.
