Laminar Air Flow Cabinets

Many microbiological and cell culture laboratories require highly sterile working environment for performing research activities and Laminar Air Flow Cabinets are the best solution for them. Often called laminar air flow chambers or laminar air flow workstations, these cabinets are designed to keep contents of the work zone safe from particulates that are sensitive to such contamination.

A laminar air flow cabinet maintains a unidirectional flow of HEPA-filtered air over the work area and protects the working environment from dust and other air-born particulates. The flow can be horizontal (parallel to the work surface) or vertical (from top to the work surface). Both the air flow types have their own significance in research. The question, where to use horizontal air flow cabinet or vertical air flow cabinet, this choice solely depends upon the requirements of applications.

Vertical Vs Horizontal Laminar Flow
As mentioned above, in a horizontal air flow cabinet, filtered air blows across the work zone in horizontal direction; this constant flow of air provides material and product protection. Whereas, in a vertical laminar air flow cabinet, filtered air blows on the work zone and leaves through the holes in the base. As compared to horizontal type, vertical flow cabinet can provide greater operator protection. Furthermore, it is user preference that decides which type of laminar air flow cabinet should use.
