The vacuum furnace range offered by Carbolite Gero includes vacuum chamber furnaces, vacuum hood furnaces, bottom loading furnaces, laboratory vacuum furnaces, and vacuum tube furnaces. Each furnace can be used with either a reactive gas or an inert gas. The majority of products in our vacuum furnace range are available with either metal, graphite, or ceramic insulation. On request, graphite models can be configured to safely operate at up to 3000°C.
