JK-1700VT 1700C Vertical Tube furnace is a CE certified lab tube furnace using high quality ceramic fiber board and MoSi2 heating elemen. Vacuum sealed flange with two valves & vacuum gauge, and High purity Alumina tube are included for immediate use. The temperature of Vertical Tube furnace is controlled by high precision controller with accuracy +/-0.5C and 51 segments programmable up to 1700C. It is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition.

Vertical Tube Furnace Construction:

• 1800 type high purity ceramic fiber insulation (energy saving 40% and weight lighter about 30% than old furnace )
• Double layers steel casing with fan cooling, to ensure the surface of furnace below 50C
• High purity Alumina tube as furnace tube
