SVAC4, 4.5 Cu.Ft. (127.5L) Microprocessor Controlled Vacuum Oven for Drying and Bake out

The SVAC4 has a double plenum design exceeds CE safety requirements resulting in a cool outer surface.

Innovative Design – The doors have positive latch handles with spring-loaded glass to facilitate a good vacuum seal without hinge binds that shorten the gasket life. A selection of gaskets (for specific applications) and a small bench top footprint increase the versatility of our ovens. We were the first to bring square vacuum ovens to the industry and we continue to offer innovative, top-of-the-line vacuum ovens. Our unique cross-flow ventilation forces inert gas to fill the entire chamber.

Versatile – Chose from 3/8 inch orifice or a KF25 fitting to withstand heavy use, minimize draw-down time and achieve low vacuum levels. We offer a full line of gaskets to suit applications involving high temperatures, acids, or solvents.
