Three Zone Alumina Tube Furnace with Vacuum Flanges

HTTF-1700-III high temperature tube furnace is a three zones tube furnace with complete vacuum sealing flange. Each heating zone is 12" in length and controlled by three precision 30 segments of digital temperature controllers independently. laboratory tube furnace can create the various thermal gradient by adjusting three zones temperature. It is an excellent vacuum tube furnace to prepare functional materials under thermal gradient.

The HTTF-1700-III high temperature tube furnace is a CE certified 60mm or 80mm OD three zones tube furnace with complete vacuum sealing flange. Each heating zone is 12" in length and controlled by three precision 30 segments of digital temperature controllers independently. One zone (center zone) is heated by Super-1800 MoSi2 elements up to 1700°C, and another two zones are heated by SiC elements up to 1400°C.  laboratory tube furnace can create the various thermal gradient by adjusting three zones temperature. It is an excellent vacuum tube furnace to prepare functional materials under thermal gradient, and also can be used for epitaxial film growth by CVD.

Two porous ceramic blocks are included for protecting flange from heating radiation

Vacuum pressure  can reach to 10-4 torr with the turbo vacuum pump

Fitting Ports

In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please click underline to order.

For supplying high-pressure gas, you may replace the standard barbed hose fitting with the Swagelok Tube Fitting

Temperature Controllers

Three digital controllers with microprocessor-based PID control and self-tuning

Warnings

The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI 

Never use graphite crucible in the alumina tube.

Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. 

 The gas flow rate should be limited to < 200 SCCM (or 200ml/min)

Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
