The tempered safety glass has held up well, resisting scratches and maintaining excellent visibility. Compared to our previous open-bench setup, the reduction in airborne particulate contamination has been significant, noticeably improving measurement accuracy and reducing the risk of exposure for personnel. It has surpassed my expectations.
Breaking Down the Features of Labconco XPert Balance Enclosures, Labconco 3930442
Specifications
- Interior Dimensions: The enclosure features a deep 59.4 cm (23 13/32″) interior. This ample space easily accommodates large micro and analytical balances.
- Airflow Design: The Clean-Sweep airfoil is a key feature. It sweeps the work surface for maximum containment and pulls air under the airfoil to create a constant barrier of protection.
- Material Construction: It boasts a glacier white and gray, dry powder epoxy-coated aluminum frame and steel rear plenum and baffle. This construction dissipates static charge.
- Sash and Viewing Panels: The enclosure includes a tempered safety glass front sash, sides, and top. These offer excellent visibility, ambient light, and protection.
- Operating Sash Height: Models with interior heights of 59.4cm (23 3/8″) have an operating sash height of 20.3cm (8″). Conservative operating sash heights limit exhaust demand, conserve tempered room air, and require a smaller remote blower than most fume hoods.
- Exhaust Collar: The enclosure features a 5.1×25.4cm (2×10″) rectangular exhaust collar on the top and bottom. This feature allows for connection to ductwork or a portable exhauster.
- Optional Airflow Monitor: Enclosures also feature an optional built-in airflow monitor. This monitors the hood’s face velocity, triggering an alarm if it falls below the setpoint.
These specifications are critical for ensuring both user safety and accurate measurements. The spacious interior allows for comfortable operation, while the airflow design effectively contains potentially hazardous materials.
