How do you clean a laminar flow hood before and after use?
Clean the ceiling of the unit first. Clean the back wall (of a vertical laminar flow hood) next, going from top to bottom. Clean the sides (swiping from top to bottom in overlapping lines). The work surface should be the last surface cleaned, beginning in the back and ending at the front of the unit.

How you will sterilize a laminar air flow before doing work?
Laminar air flow does sterilization by using “ultraviolet light”. Air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user. Due to the direction of air flow, the sample is protected from the user but the user is not protected from the sample.
What is most commonly used to clean a laminar flow hood?
*Recommended Cleaning Solutions Purair® LF Series Laminar Flow Cabinets can be cleaned with 70% ethanol or 3%-6% hydrogen peroxide. Purair FLOW and Purair PCR cabinets should be cleaned with 3%-6% hydrogen peroxide as it is more gentle on the polycarbonate construction.
