Clean rooms

We inspect your rooms.
Dohm Pharmaceutical Engineering conducts qualification and maintenance-measurements in clean rooms for you. For this purpose, we use our own testing equipment that is retraceable calibrated to national and international standards. Our company is accredited since 2009 for the measuring methods at the DAkkS (German Accreditation Council) according to ISO 14644 part 1 and 3. Our services at a glance: 

  • Air velocity and airflow measurements to determine the room air supply and exchange rate.
  • Evidence of a low-turbulence displacement air flow (TAV) (engl. uni-directional air flow - UDAF) within purity class A in compliance with EC-GMP-Guide, Annex 1 or in microbiological safety work benches 
  • Integrity tests at terminal HEPA-filters (in clean rooms with turbulent mixed ventilation, in TAV-areas or microbiological safety work benches) 
  • Determination of purity/contamination level and recovery test 
  • Determination of parameters of the premise (Temperature, relative humidity, acoustic pressure level) 
  • Evidence of the differential pressure cascade
  • Flow visualization (both in theory and practice) 
  • Complete qualification measurements of microbiological safety work benches 
  • "Limitation-of-risks (LR) method" on Insulators
