Item Number: GSL-2000X-25

EQ-GSL-2000X-25 is a ultra-high temperature vacuum / inert gas furnace with 1" I.D x 6" L heating chamber up to 2000^oC for materials research. This compact vacuum/inert gas furnace uses a special tungsten coil as heating element to reach high temperatures at low power. Precision digital controller provides stable temperature control via C Type thermocouple and SCR power supply.
