SpillStopper Work Surfaces are compatible with Protector (Premier or XStream) Laboratory Hoods with Eco-Foil(TM) Air Foil. Molded from a special formulation of corrosion-resistant epoxy resins, these work surfaces are dished and contoured to conform to the interior liner of Protector Laboratory Hoods. The front edge has a large radius to aerodynamically direct airflow into the fume hood. Pre-drilled holes for venting and plumbing passthroughs are provided. Some include 6" x 3" cupsink cutouts.
