The patented Protector Classmate Laboratory Hood is designed to meet the needs of instructional laboratories. Clear back and sides and taller front viewing window provide enhanced visibility for conducting chemistry demonstrations or observing students using the hood. The clear back also does not obstruct visibility when hoods are placed back-to-back in an island configuration. Fully-featured with baffle and air foil, this by-pass hood maintains safe airflow while the restricted sash opening conserves energy. The Protector Classmate Hood is benchtop design and offered in 4', 5', and 6' widths.
