A balance enclosure for critical weighing procedures

| By Mary Page Bailey and Gerald Ondrey

The VSE balance enclosure (photo) is offered in widths of 24, 36 and 48 in., in order to accommodate an analytical balance and other small-scale laboratory processes. Constructed of chemical-resistant metal framing and 1/4-in. thick clear acrylic side panels and viewing sash. Efficient airflow design with airfoil and bypass directs contaminants to baffled exhaust, thereby providing superior airflow and containment performance for user protection. The viewing sash is angled 15 deg for ease of viewing, with 8-in. reach-in opening height. The sash swings upward to provide 20 in. of access opening. Two service ports are located in lower-right and left-rear wall. — Hemco Corp., Independence, Mo.
