GSL-1700X-50VTB is a high-temperature hybrid box and tube furnace. It is designed for heat treatment of all types of new materials, both under vacuum or in air, up to 1700^oC. High precision SCR power controller controls the temperature of the GSL-1700X-50VT with accuracy +/-1 ^oC and 30 segments programmable up to 1700 °C

This furnace can also be used for testing the SOFC coin cell

Temperature Controller	PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor. 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Please click here to learn why SCR is more accurate than SSC (Solid state relay). Built-in over-temperature alarm and protection allow for operation without an attendant. +/- 1 ºC temperature accuracy. RS485 Communication Port Optional: The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at extra cost. If you order the PC control module together with the furnace. We recommend you order a laptop from us to avoid software installation problems. For more information please click here
Processing Tube and Crucible	99.5%High purity Al₂O₃ Ceramic ID: 50 mm; OD: 40 mm x Length 1000 mm Two fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) 4 alumina crucibles of 15mm Dia x 15 mm H are included
Vacuum Sealing Flanges	One pair sealing flange with double silicone high-temperature O-ring is included. Two SS needle valves and one dial vacuum gauge are installed with a flange for immediate use. Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^^-5torr by turbo molecular pump. Please click the picture below to see flange assembling details.
Fitting Ports	Standard 1/4‘’ Barbed fittings with needle valves. For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting, please click underlined to order. Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please click the underlined to order. Optional: You may also consider using the parts in below to increase the vacuum efficiency Please click here to order a digital vacuum gauge for precision vacuum control up to 10^-4 torr (see picture below and click to enlarge) You may click here to order a flow meter and install it in a tube flange (see picture below) KF25 Stainless steel Bellows KF25 Quick Clamps
Vacuum Level	50 m-torr can be achieved by a mechanical pump 10^-5 torr can be reached by molecular pump The vacuum pump is not included, please order separately by clickinghere
