These units provide exceptional capabilities for fast and gentle drying of heat sensitive materials. They prevent residue accumulation on products and also allow safe drying of flammable solvents. They are built with a stainless steel chamber for exceptional durability, and its unique cross-flow ventilation forces inert gas to fill the entire chamber. The doors on these units have positive latch handles with spring-loaded glass to facilitate a good vacuum seal without hinge binds that shorten the gasket life. The tempered glass viewing window allows for safe, continuous monitoring of samples.
