    Laboratory Fume Hoods and Chemical Fume Hoods

    Saturday, March 28, 2009
    A laboratory fume hood is arguably the single most important piece of safety equipment in a lab. A lab worker may never use the fire extinguisher or the eye wash, but the lab fume hood is used on a da... Read More

    Laminar Flow Hoods and Biological Safety Cabinets

    Monday, April 06, 2009
    Laminar flow hoods fall in to two basic categories: biological safety cabinets (or biosafety cabinets) and laminar flow clean benches. These categories differ in the level of protection provided to th... Read More

    Temperature Chambers and Environmental Test Chambers

    Monday, April 20, 2009
    The best way to understand how a product or material will perform in the field or over time is to use a laboratory test chamber to model those conditions. This is done in one of two ways: the test cha... Read More
