The Plastic Concepts, Inc. Cleanroom Pass-Through is designed to minimize contaminants within the controlled environment. Pass-throughs are made of ½" thick stress relieved polypropylene, a highly durable and non-corrosive thermoplastic, highly resistant to most acids, solvents and other corrosives. The Passthough comes standard with ½" thick clear acrylic doors giving the user full view of the pass-though. The compression latches along with the gaskets, provide easy operation and maximum pressure to ensure a proper seal in the chamber. The Plastic Concepts Pass-Though is available in many sizes and custom sizing is available on request.
