XPert weigh box

The XPert weigh box has inlet and outlet HEPA filters, and serves as a physical barrier to protect the operator from hazardous airborne particulates and powders in a leakfree environment. It has a static-pressure gage that monitors HEPA filter loading, an anti-static ionizer fan mounted on the interior of the box to reduce static charge, and a balance vibration isolator for delicate weighing operations. It also has a seamless one-piece, molded poly_ethylene shell that provides chemical resistance and can be cleaned easily. The viewing window is 0.25-in.-thick laminated safety glass that is removable for loading equipment. The inner and outer transfer chamber doors pivot upward and are counterbalanced and equipped with quick-latches. The main chamber interior is 13 ft3 and the transfer chamber has an 11-in.-nominal dia.
