GSL-1800X-K60 is a bench-top tube furnace with Kanthal Super-1900C Grade MoSi2 Heating Elements and high-quality alumina refractory board with ZrO2 liner. Vacuum sealing flanges with valves, a vacuum gauge,  and a high-purity alumina processing tube (60mm O.Dx 1000mm L) are included for immediate use. The temperature of the GSL-1800X-K60 tube furnace is controlled by a 30-segment programmable high-precision SCR (Silicon Controlled Rectifier) digital controller with an accuracy of +/-1 ºC. This tube furnace has a max. working temperature up to 1800 ºC. It is widely used in material & chemical research labs to sinter all types of new material samples under vacuum and other gas conditions.
