large diameter 3 Zone Tube Furnace with 6" - 11" Quartz tube and Flange (1100C, 12"+12"+12" Heating Zone) - GSL-1100X-XX-III

Product Description

 GSL-1100X-XX-III furnace is a CE certified three zone tube furnace with 6", 8.5" or 11"O.D quartz tube and vacuum flanges. Needle valves and, vacuum gauge are pre-installed for immediate use. Three 30 segment programmable controllers are built in with K type thermal couple. Microprocessor-based PID control provides excellent control without overshooting and +/- 1 ºC accuracy. It has been widely used for materials or chemical lab for sintering all types of new material samples under vacuum or other gases conditions. It is an excellent tool for annealing, diffusing and sintering processes.
