Protector Work Stations
Protector Work Stations deliver targeted protection for pathologists and histotechnologists working with solvent vapors associated with gross sectioning, trimming, coverslipping, and staining procedures. These specialized enclosures utilize patented containment-enhancing features and face velocities from 60 to 100 fpm to effectively remove chemical vapors from the laboratory environment.
Configuration Options
Two distinct configurations address different facility requirements. Models equipped with built-in blowers accommodate two large carbon filters—Organic, Formaldehyde, and Ammonia—in any combination, keeping low concentrations of these chemicals below OSHA-recommended time-weighted average levels while returning filtered air to the laboratory. Alternatively, models designed for connection to remote blowers or house exhaust systems provide protection from a broader range of chemicals, recommended when concentrations are high, unknown, or unpredictable. These models may also connect to FilterMate Portable Exhausters for filtered air return without outside ducting.

Patented Containment Technology
- Clean-Sweep air foil sweeps the work surface for maximum containment with airflow openings creating a constant barrier of clean air protection
- Upper containment sash foil directs contaminants away from operator breathing zones
- Upper dilution air supply introduces room air at the top of the sash to dilute upper chamber contaminants and bathe the sash back with clean air
- Type 304 stainless steel rear baffle with zone perforations promotes horizontal laminar airflow, pivots down and removes easily for cleaning
- Side-entry air foils sweep across interior glass surfaces to enhance containment
