  • Check the head holes are not blocked

Weekly / per campaign

  • Sterilise heads by autoclaving where validated
  • Check battery health

Annual (or as per manufacturer)

  • Airflow calibration against a traceable flow meter
  • Manufacturer service: fan, sensor and seals
  • Review of collection efficiency data for the head type
SAFETY

Safety precautions

Before you work on the Air sampler
  • Follow cleanroom gowning when sampling in classified areas.
  • Handle autoclaved heads with heat-resistant gloves.
  • Treat incubated plates as potentially infectious.
