Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction. The process of laminar air flow can be described as airflow where an entire body of air flows with steady, uniform velocity. Laminar Flow Cabinets work by the use of in-flow laminar air drawn through one or more HEPA filters, designed to create a particle-free working environment and provide product protection.
Laminar flow cabinets may have a UV-C germicidal lamp to sterilize the interior and contents before usage to prevent contamination of the experiment. ... The light must be switched off when the cabinet is being used. Many applications call for Laminar Flow Hoods that provide ISO 5/Class 100 HEPA-filtered air which removes organisms and particulates 0.3 micron in size with an efficiency of 99.99%
Clean benches and biological safety cabinets are common examples of laminar flow hoods. They are laboratory enclosures designed to carefully direct HEPA filtered air. Some of these hoods protect items placed on the work surface from contamination. Others prevent exposing the user to contaminants in the work area. Laminar flow hoods are often used to work with biological samples, semiconductors or other sensitive materials.
The laminar air flow principle was first developed in the early 1960s. It's still incredibly relevant for modern labs, having literally shaped the way air safely moves in many generations of laboratory enclosures. Today, many categories of laminar flow hoods exist. Although they differ depending on the science performed within, there is one common denominator: all use this type of unidirectional airflow to aid in maintaining sterility, preventing cross-contamination and reducing turbulence.
