The Series STM 230V round bottom flask heating mantle is aluminum housed to provide strength and durability while supporting the weight of the vessel. Fabric interior to softly nest glass vessels and reduce the chance of thermal shock. Adaptable to most vessels including larger sizes. Withstands 600° C internal operating temperature and resists burnout. The STM Series can be adapted to special applications with custom sizes, bottom holes, and special electrical devices. The Series STM spherical flask mantle covers only the flask's bottom half, letting you see its full contents. Larger sizes have multiple circuits for ease of temperature control when a flask is less than half full. H1375-11 and H1375-12 have 3" legs for cool lab benches, are sealed, and have inert gas purge fittings. Splash Guards can be used with H1375-4 through H1375-11E. Poncho Safety Shields can be used with sizes 500 mL and larger. Supplied without controller. NOTE: 230V units are not returnable.
