Product Description This Labconco XPert 3971662 low-profile enclosure provides user protection by keeping powders, particulates, and fumes contained during weighing procedures. The interior easily accommodates large micro and analytical balances. The Clean-Sweep airfoil allows air to sweep the work surface for maximum containment. Airflow openings pull air under the airfoil, creating a constant barrier of protection from contaminants. The upper containment sash foil bleeds air into the enclosure to direct concentrations of contaminants away from the operator's breathing zone. The upper dilution air supply introduces room air at the top of the sash to dilute contaminants in the upper chamber and bathes the back of the sash with clean air. The perforated rear baffle promotes horizontal laminar airflow to maximize containment. Side-entry airfoils allow air to sweep across the interior glass surfaces to enhance containment.
Tempered safety glass front sash, sides, and top offer excellent visibility, ambient light, and protection. Has an operating sash height of 30.5cm (12"). Conservative operating sash heights limit exhaust demand, conserve tempered room air, and require a smaller remote blower (additional cost) than most fume hoods. Ergonomic angled sash allows a closer view, reduces glare, and provides a more comfortable operating position than vertical sashes. The hinged sash pivots upward and locks to a loading height of 48.3cm (19"). Includes a left side-mounted waste chute that accepts bags 25.4 x 40.6cm (10x16") and larger. Utility ports allow passage of tubing and cords.
Enclosures also feature a built-in airflow monitor. If the hood's face velocity falls below the setpoint for more than six seconds, an audible alarm sounds and a red light glows. The alarm can be muted. On the Guardian monitor, an LED glows green when the airflow is within setpoint range. The Guardian 1000 digital monitor features an LCD display of actual face velocity and an RS-232 port. Applications involving high concentrations of solvents may require an explosion-proof blower (not included). Stainless steel work surfaces feature a spill trough. The utility shelf kit has three epoxy-coated steel shelves that can hold a printer, utensils, and other miscellaneous supplies. Shelves attach to the rear baffle perforations of the enclosure.
