Compact 1600C Tube Furnace with 50mm Alumina Tube & Vacuum Flanges / Valves - GSL-1600X-50-UL

0.0/5 rating (0 votes)


GSL-1600X-50-UL is a compact 50mm (2") tube furnace with Kanthal 1650 oC Grade SiC Rods  heating elements. It is widely used in material & chemical labs to sinter all types of new material samples under vacuum or other gas conditions up to 1600oC. The temperature of the furnace is controlled by a 30 segment programmable high precision SCR (Silicon Controlled Rectifier) digital controller with the accuracy of +/-1 oC. High-quality alumina tube, vacuum flanges with valves, and pressure gauge are included for immediate use. The tube furnace can be placed into a glove box to process material in various atmospheres.
