Overview

X Pert Balance Enclosures provide user protection by keeping powders, particulates and fume contained during weighing procedures. They are well suited for pharmaceutical research and other laboratory applications involving weighing of toxic substances. These vented balance safety enclosures may be dusted to the outside or connected to the Filter Mate Portable Exhausted to be exhausted back into the laboratory through HEPA filters, carbon filters, or a combination of both HEPA and carbon filters.

Their ample, 23″ interior depth (30″ depth for “Deep” models) easily accommodates large micro and analytical balances, and a true bag-in/ragout filter disposal system allows safe filter replacement.

Description

Features

Low profile fits in tight spaces
Deep 23″ or 30″ interior easily accommodates large micro and analytical balances
Patented Clean-Sweep™ air foil allows air to sweep the work surface for maximum containment
Upper containment sash foil bleeds air into the enclosure to direct concentrations of contaminants away
from the operator’s breathing zone
Upper dilution air supply introduces room air at the top of the sash to dilute concentrations in the upper
chamber and bathes the back of the sash with clean air
Patented* rear baffle with zones of perforations promotes horizontal laminar airflow to maximise
containment. Airflow openings pull inflow air from under the air foil so that clean air continually flows over
the air foil creating a constant barrier of protection from contaminants
Side-entry air foils allow air to sweep across the interior glass surfaces to enhance containment
Sturdy glacier white and Gray, dry powder epoxy-coated aluminium frame and steel rear plenum and baffle
dissipate static charge and provide durability and better corrosion resistance compared to acrylic models.
No unreliable plastic-to-plastic bonding is used
Tempered safety glass front sash, sides and top offer excellent visibility, ambient light and protection. Glass
provides improved fire, scratch and corrosion resistance than acrylic and dissipates static charge.
8″, 10″ or 12″ high sash opening limits exhaust demand, conserves costly tempered room air and requires a
smaller remote blower than most fume hoods
Ergonomic 20° 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 20″
Two utility ports with iris openings allow passage of tubing, electrical cords and interface cables from inside to back exterior for connection to services
Flexible exhaust options. 2″ x 10″ rectangular exhaust collars on the top and bottom allow the XPert
Balance Enclosure to be connected connected to ductwork for exhausting to the outside or to a Filter Mate™
Portable Exhausted for filtered removal of powders, particulates or fumes. Using the bottom exhaust collar keeps ductwork hidden, maximising room visibility.
Particulate containment independently verified by Safe Bridge Consultants, Inc
ASHRAE 110-1995 conformity as independently verified by ECT, Inc
Free validation package available. Contains Safe Bridge Consultants, Inc. and ECT, Inc. Test Reports; Installation Qualification/ Operation Qualification (IQ/OQ) Protocol; and Maintenance Log.
