2800°C Graphitization Chamber Furnace - GSL-2800-GRF

 GSL2800XGRF is a high-temperature graphitization furnace up to 2800°C using graphite heating elements. It comes with multiple layers of graphite felt thermal insulation and a water-cooled stainless steel chamber. The equipment also features a bottom-loading sample stage for easy sample loading and retrieval. The chamber has a vacuum pressure rating <5e-3 torr with a mechanical pump.
