Protector Work Stations are specifically designed for the needs of pathologists and histotechnologists. Like a traditional fume hood, these enclosures have a front air foil and rear baffle to direct the inflow air across the work area and away from the operator. Ideal for cramped or crowded labs, Protector Work Stations have a low profile so they fit easily under standard upper cabinets.

Protector Work Stations designed for ducting to the outside are available with or without a built-in blower. If there is no feasible way to vent to the outside, models with a built-in blower are available that use specially-treated Carbon Filters. These filter packs keep low level concentrations of toluene, xylene, formalin, formaldehyde and other solvents below their OSHA-recommended, time-weighted averages, restoring clean air to the laboratory.
