The XPert Filtered Balance System (Cat # 3971301) provides user protection by keeping powders and particulates contained during weighing procedures. The built-in blower and exhaust HEPA filter mounted in the upper plenum take up less space than a separate exhauster would require, and isolation supports minimize blower vibration. RXPert Single Filtered Balance Systems are Class I biological safety cabinets designed for drug compounding and manipulation of pharmaceutical ingredients. They meet the USP <800> requirements for non-sterile compounding when ducted and include a factory-installed canopy and damper for thimble ducting to the outside. Their true bag-in/bag-out HEPA filter disposal system provides safe filter replacement.

Since HEPA filtered air is returned to the laboratory, these vented balance enclosures offer the added benefit of low installation costs and require no ducting to the outside. Interior dimensions accommodate large micro and analytical balances. Containment-enhancing features ensure that potent powders frequently found in pharmaceutical, dry chemical, mold and asbestos weighing operations are kept away from the operator.

This system has hardly been used and is in premium condition. It is being offered at around half the cost of a new one.  The system comes with a 60-day warranty, stainless steel work surface, and a telescoping base stand.
