1750ºC Bench-Top Vacuum and Atmosphere Tube Furnace ( 60mm OD) with Kathal Super-1800 Heating Elements - GSL-1750X-60


In stock
Item Number: GSL1750X60
4 -6 weeks to delivery for QC
GSL-1750X-60 is a CE-certified compact tube furnace with  Kathal Super-1800C Grade MoSi2 Heating Elements and high-quality alumina refractory board. Vacuum sealing flanges with valves, vacuum gauge,  and an 80mm dia. A high purity alumina processing tube is included for immediate use.  The temperature of the GSL-1750X-60 tube furnace is controlled by a 30 segment programmable high precision SCR (Silicon Controlled Rectifier) digital controller with an accuracy of +/-1 ºC. This tube furnace has a max. working temperature up to 1750 ºC. It is widely used in material & chemical research labs to sinter all types of new material samples under vacuum and other gas conditions.

Heating Elements

Kathal Super 1800C grade heating elements- 330mm L, 8pcsmade in Sweden
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 attendance.
  • +/- 1 ºC temperature accuracy.
  • RS485 Communication Port.
  • Optional:  
    • The furnace may be operated by PC by installing a control module. Please order a MTS-02 control module at extra cost.  
    • If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer (laptop) from us to avoid software installation problems. For more information please click here.
                         
             
Tube Materials High purity Al2O3 ceramic, Purity > 99.9%
Processing Tube
  • Premier Grade alumina tube made in the USA
  • 54mm ID x 60 mm OD x 1000 mm length.
  • Four fiberous 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).
  • Quartz blocks (optional) are ideal for a cleaner processing environment and higher vacuum efficiency.
                     
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 flange for immediate use. 
  • Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^-5 torr by turbo molecular pump. Please click picture below to see flange assembling details.
