Our revamped SHEL LAB SVAC vacuum ovens provide exceptional capabilities for fast and gentle drying of heat sensitive materials.
Vacuum ovens prevent residue accumulation on products and use lower temperatures than typical convection ovens. Your products are processed with minimal impact and maximum throughput. 
SHEL LAB vacuum ovens have stainless steel interiors and provide exceptional durability and stability. Available in 3 sizes, SVAC Vacuum Ovens support a diverse array of applications. Our upgraded SVACS meet UL, CSA, and CE safety requirements resulting in a cool outer surface. To achieve required vacuum levels, users can choose from a 3/8-inch orifice or a KF-25 fitting to withstand heavy use and minimize draw-down time.
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.
The SHEL LAB Vacuum Ovens are equipped with silicone gaskets. While these gaskets resist a wide variety of temperatures and pressures, they can break down in the presence of solvents and acids. For solvent applications, we recommend using Buna gaskets. For acidic applications, we recommend using Fluorosilicone or Viton® gaskets.
