  • Room differential pressure (DAP)
  • Filter system integrity test (DEHS)
  • Cleanroom classification (according to ISO 14644 and GMP guidelines)
  • Recovery test (recovery time)
  • Microbiological sampling, airborne and surface
  • Compressed air parameters (particles, aerosol oil content, dew point, microbiological)
  • Rating-related work for hospitals according to standards and regulations
  • Sound levels and luminosity
  • Smoke studies
  • Maintenance of filters including changes and installations

The Swiss Accreditation Service (SAS) grants to CAS the accreditation as testing laboratory for the testing of cleanroom systems in accordance with ISO/IEC 17025. The scope of the STS0566 accreditation is defined in the Official Directory of the Accredited Testing Laboratories.

GMP Services: Thermal Validation

The CAS Thermal Validation team uses high-precision measuring systems to perform thermal process ratings according to your requirements. Our advanced practical knowledge allows us to meet your needs, whether you require routine validation outsourcing or project support. Well-equipped and with highly technical experience, we perform on-site validation for:

  • Steam and dry heat sterilization processes
  • Temperature and humidity mappings
  • Cooling and heating processes
  • Freezing and thawing processes

We provide experienced services for autoclaving, SIPprocesses (e.g. vessels, filling lines, freeze dryers, stopper sterilization), sterile tunnels and hot-air apparatuses, in addition to cooling and heating devices (e.g. freezers, ultra-deep freezers, liquid nitrogen storage tanks, incubators, climatic chambers, cold and storage rooms, warehouses). Thereby, we ensure operational competences and support you with customer-fit documentation like validation plans, reports and SOP’s for your system validation.

PMS/CAS conforms with international guidelines and country regulations. We use state-of-the-art measurement instruments and promise traceable certificates of calibration.
