Downflow velocity test measures the downward movement of the air in the cabinet. It also determines the performance of the blower/s.

Filter integrity test verifies the continued efficiency of the filter by introducing particulates and measuring the output.

Inflow velocity test measures the inlet volumetric flow rate at the front aperture at nominal operating speed.

Light intensity test determines fluorescent lamp’s light intensity from the front to back centerline work surface level of the cabinet.

Noise level test is used to obtain the noise level of the cabinet during normal operation.*

Site Assessment Test evaluates the location if it meets the cabinet's installation requirements.

UV intensity test determines the light intensity of the UV lamp from the front to back centerline work surface level of the cabinet.*

*This test is optional for field testing.


Decontamination guarantees ready and safe usage of Biosafety Cabinets after installation, relocation, or filter replacement. It is done through exposing the work surfaces, exhaust filters, surfaces of the air plenums, and the fan unit to formaldehyde or hydrogen peroxide gas.
