HEMCO is unveiling its new fume hoods, designed specifically for applications in which accurate testing requires nonmetallic materials. The fume chamber and integral work surface is welded one piece seamless of white polypropylene, and the baffle is fabricated from the same material. The exterior is constructed of chemical and flame-resistant white composite resin. Trace metals fume hoods are ideal for water treatment, marine and soil sciences, environmental toxic analysis, and toxicology. The fume hood is offered in 48-inch, 60-inch, 72-inch, and 96-inch widths in either 30-inch or 36-inch depths.
