Product Category Description:
XPert* Filtered Balance Stations, Labconco*
These stations provide user protection by keeping powders and particulates contained during weighing procedures. The built-in HEPA filter is mounted in the upper plenum and an exhaust collar allows connection to 15.2cm dia. (6") ductwork and a remote blower.
The deep interiors easily accommodate large micro and analytical balances. The Clean-Sweep* airfoil allows air to sweep the work surface for maximum containment. The perforated rear baffle promotes horizontal laminar airflow to maximize containment. 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 bathe the back of the sash with clean air. Additional side-entry airfoils allow air to sweep across the interior glass surfaces to enhance containment. The airfoil’s ergonomic design provides a comfortable position for the operator’s forearms.
Stations feature a true bag-in/bag-out filter disposal system for safely removing and replacing the HEPA filter. The HEPA filter cell is 99.99% efficient on particulates 0.3µm in size. An upper diffuser screen, located above the work area, provides protection for the HEPA filter. The station also features a front-mounted Minihelic* pressure gauge that monitors pressure differential across the HEPA filter to help determine filter loading.
Sturdy glacier white and gray, dry powder epoxy-coated aluminum frame and steel rear plenum and baffle dissipate static charge. Tempered safety glass front sash, sides, and top offer excellent visibility, ambient light, and protection. The 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") on the 0.6m (2'), 0.9m (3'), and 1.2m (4') models. The 1.5m (5') and 1.8m (6') models incorporate a gas-assist lift and have a loading height of 70.4cm (2711/16"). The operating sash height is 23.9cm (913/32") on the 0.6m (2'), 0.9m (3'), and 1.2m (4') models. The 1.5m (5') and 1.8m (6') models have a 30.5cm (12") operating height. A wiping seal helps to keep contaminants contained. Stations also include front-mounted light and blower switches, two utility ports, and glare-free fluorescent lighting.
Enclosures also feature an optional 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 screen of actual face velocity and an RS-232 port. 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.
All stations conform to modified ASHRAE 110-1995 standards, SEFA 1-2002 standards, and ANSI Z9.5-1-993 standards. The 115V models are ETL and ETL-C listed; the 230V models are CE marked.
Ordering Information: All stations require a supporting base, remote blower, and ductwork. For base cabinets, see the Protector* acid storage cabinets (46610-412 series), solvent storage cabinets (46610-440 series), and standard cabinets (46610-404 series). The 1.5m (5') and 1.8m (6') models with an exterior depth of 93.4cm (3613/16") include a left side-mounted waste chute that accepts bags 21.6x27.9cm (81/2x11") and larger. The 230V models do not include a plug.
