JK 1400C Vacuum Sintering Furnace is a CE certified lab furnace using high quality ceramic fiber board with ZrO2 Liner and high quality super SiC (Silicon Carbide) heating elements. Vacuum sealed flange with two valves & vacuum gauge are included for immediate use. The temperature of 1400C Vacuum Furnace is controlled by high precision controller with accuracy +/-1C and 51 segments programmable up to 1400C.

It is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition.


JK-1400 Vacuum Sintering Furnace Features:

1) High quality super SiC (Silicon Carbide) heating elements serve as heating element and can be heated up to 1400C;
2) High quality ceramic fiber board with ZrO2 Liner;
3) Effective heated chamber: 20"x20"x20";

4) The furnace temperature is controlled by precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/-1C and 51 segments programmable up to 1400C;
5) Built in precision digital temperature controller is 51 segments programmable to control heating rate, cooling rate and dwell time;
6) All accessories are included for immediate use, including:
--Stainless steel vacuum flange with needle vacuum connector and two needle valves are installed on top;
--Heavy duty high speed mechanical pump and stainless steel included vacuum pipe are included;
--Compact Digital Vacuum Gauge & Controller;

--Double Step Rotary Vane Vacuum Pump;
--PID automatic controller.
