Laminar Flow Cabinets are enclosed benches designed to prevent contamination to any particle sensitive materials. To warrant hassle-free operation, regular testing and maintenance should be done at least annually.
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.
Light intensity test determines fluorescent lamp’s light intensity from the front to back centerline work surface level of the cabinet.
Noise Level tests is used to obtain the noise level of the cabinet during normal operation.*
Particle count test determines the air quality by counting and sizing the number of particles in the air and classify cleanliness level in a controlled environment.
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.
