![]() ![]() Just what exactly is laminar air flow, why is it effective and what does it look like in labs today? Let's explore. 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. Today, many categories of laminar flow hoods exist. It's still incredibly relevant for modern labs, having literally shaped the way air safely moves in many generations of laboratory enclosures. Laminar flow hoods are often used to work with biological samples, semiconductors or other sensitive materials, and are commonly referred to in laboratories as cell culture hoods or tissue culture hoods.Īccording to the CDC, the laminar air flow principle was first developed in the early 1960s. Others prevent exposing the user to contaminants in the work area. Some of these hoods protect items placed on the work surface from contamination. They are laboratory enclosures designed to carefully direct HEPA filtered air. cell culture hood or tissue culture hood). ![]() Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction.Ĭlean benches and biological safety cabinets are common examples of laminar flow hoods (a.k.a. ![]() Traps and Other Vacuum Pump Accessoriesīy Elizabeth Dille, Ph.D., Product Manager.Miscellaneous Freeze Dry Parts & Accessories.Kjeldahl, Fat & Crude Fiber Apparatus Accessories.Dry Evaporators, Concentrators & Cold Traps.Class II, Type B2 (Total Exhaust) Biosafety Cabinets.Biosafety Cabinet & Clean Bench Accessories.Balance, Bulk Powder & Equipment Enclosures.Biological Safety Cabinets & Enclosures. ![]()
