The VSE enclosure (photo) is offered in 24-, 36- and 48-in. widths to accommodate an analytical balance and other small-scale laboratory processes. The enclosures are constructed of chemical-resistant metal framing and 1/4-in. thick clear acrylic side panels and viewing sash. Efficient air-flow design with airfoil and bypass, directs contaminates to baffled exhaust, thereby providing superior airflow and containment performance for user protection. The viewing sash is angled 15 deg. for ease of viewing comfort with 8-in. reach in opening height. — Hemco Corp., Independence, Mo.
