The PureLab HE 4GB 1950 Glovebox design is based on a modular platform allowing customers to expand existing glove boxes to meet increasing working space requirements. Glove box expansion features include additional antechambers for thru-flow work processes, cold storage freezers, process vacuum ovens and furnaces, and a full line of accessories.
Inert's Gas Management Systems provide a < 1ppm O2 and H2O inert atmosphere required for a multitude of air-sensitive applications.
