The GFD (glass filter dryer) FilterBox containment system is a small-scale solution to this company’s larger FilterBox products. The FilterBox consists of an agitated nutsche filter dryer (ANFD) or GFD completely integrated within a PSL isolator, providing high containment when handling highly potent APIs (active pharmaceutical ingredients) and other highly active or cytotoxic compounds. The FilterBox achieves containment to nanogram levels protecting both the product and the operator during operations including charging, sampling, filtration, drying and discharging, as well as base opening and cleaning. The FilterBox solution is easily scalable for laboratory to industrial production, including 0.002 to 0.3 m2 ANFDs. The GFD FilterBox is part of the FilterBox family, and includes 0.002 to 0.05 m2 GFDs. — Powder Systems Ltd. (PSL), Liverpool, U.K.
