Smaller, two-glove position model of the SterilSHIELD Barrier Isolator offers a contained, positive-pressure work area. Designed for aseptic compounding of non-hazardous drugs in compliance with USP, Model SS500 creates a HEPA-filtered unidirectional airflow of better than ISO Class 5 (Class 100) air cleanliness conditions within the chamber to eliminate cross-contamination on the work surface while preventing outside contaminants from entering the chamber. The 5-ft. wide model offers a two-glove position, while the original 6-ft. wide Model SS600 offers a three-glove position in the main chamber. The ergonomic design includes a slanted view screen angled at 10° with top hinge to allow full opening for loading and unloading of pharmacy equipment; oval glove ports with two glove positions offer easy reach to all interior surfaces for users of different heights; and positive-pressure interchange (pass-thru chamber) permits safe and easy transfer of materials in or out of the chamber. Product protection is assured through a main chamber pressure that is positive to the room. A plenum design employs a high-performance airflow system that provides optimum protection from particulates, extends filter life and reduces cost of ownership. The microprocessor controller with touchpad membrane control offers simple operation without relays or switches.
