XPert Balance Enclosures provide user protection by keeping powders, particulates and fumes contained during weighing procedures. Patented (U.S. Patent No. 6,461,233) features including the Clean-Sweep air foil, upper containment sash foil and zone-perforated rear baffle maximize containment. The interior dimensions easily accommodate large micro and analytical balances. Additional patent is pending.
