Product Description

EQ-GSL-1500X-40 is a compact 42mm O.D. tube furnace using 1600^oC grade SiC rods as heating elements. It is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition.1/4" in diameter vacuum sealing assembly will connect with 1/4"rubber hose.The temperature of EQ-GSL-1500X40 tubing furnace is controlled by high precision digital controller with accuracy +/-1^oC and 51 segments programmable up to 1500^oC. The tube furnace can be placed into a glove box to process material in various atmospheres.
