Portable Glove Box (PGB)

PGB – The First Field-Deployable Class III BSC
Germfree’s PGB is the first field-deployable containment device that meets all of the requirements for a Class III Biological Safety Cabinet (BSC), as well as the standards for a glovebox by the American Glovebox Society (AGS). Weighing in at 170 lbs with the standard HEPA filtration system, this Class III BSC is lightweight, portable, and fit for a range of field applications. The PGB is easily disassembled and can be transported as two compact pieces.

The PGB, Class III BSC is constructed of all welded aluminum with a removable side airlock. The unit is powder coated with a chemically resistant coating (white standard) providing defense against agents while in the field. Portable Class III Biological Safety Cabinet features Advanced Filtration and portability. The PGB’s 915mm work height is achieved through using the aluminum case as a stand.

Portable glovebox. Unmatched flexibility.
The unit incorporates a single HEPA inlet with double HEPA exhaust, meeting Class III BSC requirements. A 10-foot flexible hose connects the PGB to the motor blower. The motor blower is outfitted with carrying handle and provides the proper operating negative pressure at 40-50 CFM of airflow.

Class III BSC’s are increasingly specified as laboratories confront a range of new and increasingly hazardous challenges. These may include new applications, new agents and enhanced safety protocols.

The PGB BSC was designed specifically to solve the primary obstacles faced in achieving Class III containment BSCs in remote areas with space constraints and cost limitations. Our engineers designed this portable Class III BSC to work within the constraints of your application without compromising on features, functionality and user comfort. The PGB delivers unmatched flexibility.
