1200C Bottom-loading Vacuum Furnace with Rapid Cooling VBF-1200X-E8 Description
1200C Bottom-loading Vacuum Furnace with Rapid Cooling VBF-1200X-E8 is a vacuum-sealed furnace featuring a motor-driven bottom-loading sample stage and an electrically operated door, providing effective thermal insulation for the heated chamber. Equipped with a quartz chamber measuring 8.5" in internal diameter and 13.4" in height, along with a water-cooled flange, this furnace enables precise heat treatment under vacuum or controlled atmospheres. To speed up the cooling process of the heated sample, a gas blow system utilizing inert gas is incorporated at the bottom.
