Service for safety cabinets

Testing, maintenance and repair of microbiological safety cabinets and cytostatic safety cabinets of all manufacturers


Servicing safety cabinets and LAF (almost all manufacturers) is our core competence. We install, check, maintain and repair the following industrial safety and product protection equipment for you.

  • Cytostatic safety cabinets
  • Microbiological safety cabinets
  • roduct protection cabinets
  • LAF (LaminarAirFlow) units


Service highlights:

  • Service of our own and third-party safety cabinets
  • Special installation in laboratories that are difficult to access
  • One partner for all safety cabinets and ventilation
  • Connection to exhaust air systems
  • Fast repair due to availability of spare parts


Only with regular inspections of your safety cabinets can you ensure safety and functionality and fulfil the legal requirements.


We carry out commissioning and routine tests for you in accordance with DIN 12980, EN 12469 and EN ISO 14644. depending on relevance and agreement. Of course, you will receive comprehensive documentation for all tests.  

1. Filter systems

  • Check HEPA and ULPA filters
  • Filter tightness test
  • Checking for leaks
  • according to VDI 2083 sheet 3 and DIN EN ISO 14644-3

2. Filter change

  • In the event of leaks, heavy loads and a reduction in filter performance
  • Risk assessment in advance
  • Possibly decontamination with H2O2
  • For large filter systems: negative pressure method for safe disposal in the event of contamination with cytostatics, TSE agents or similar

3. Air flow:

Testing and adjustment of the basic safeguards for personal, product and cross-contamination protection:
  • Low-turbulence displacement flow
  • Air intake flow
  • Effect of additional devices on air currents

4. Visualisations:

Visualisation of air flow in new buildings, conversions and central changes:
  • Displacement flow
  • Air intake flow
  • Direction and lack of turbulence of the air currents
  • Effect of people on air currents

5. Monitoring system:

Review of security systems:
  • Limit value of the displacement flow
  • Limit value of the air inlet flow
  • Front window position
  • Optical and acoustic warning signals

Service technician checks cleanroom

6. Personal protection:

Tests around the subject of personal protection:
  • KI Discus Test
  • Functional unit SWB and laboratory
  • 5-15 test cycles
  • SWB-specific operating point

7. Electrical installations:

Tests of electrical installations:

  • Protective conductor resistance
  • Insulation resistance
  • Substitute leakage current
  • In accordance to German regulations BGV A3 and DIN VDE 0701-0702

8. Lighting and UV-C radiation tests for:

  • Rated power
  • Power of UV-C lamps
  • Safe operation of the UV-C lamps

9. Sound pressure level measurement of:

  • Sound pressure level
