CASE STUDY Qualification of Laboratory Equipment

Qualification of Laboratory Equipment


A laminar flow cabinet with an A clean zone in the surroundings of the B zone.

Scope of work

The scope of qualification included the following components:

  • air handling unit,
  • filters
  • control and measurement system.


As it was legacy equipment, the DQ was limited to verifying if the equipment was still capable of satisfying the basic legal requirements according to the technical documentation. At the IQ stage, the available technical documentation was verified and the correctness of installation confirmed. The OQ and PQ qualifications were combined in one stage during which all the measurements concerning air quality and the laminarity of flow were taken and the control and monitoring system was tested.
