UL/CSA/CE Certifications:
Tube size and voltage:
GSL-1100X is a CE certified small quartz tube furnace (1~2" diameter) designed for heating small samples up to 1100oC. Stainless steel vacuum flanges with valves, vacuum pressure gauge, and quartz tube are included for immediate use. The built-in precision temperature controller can program up to 30 segments of heating, dwelling, and cooling steps. The furnace can be set up in both vertical and horizontal positions to meet various applications such as sample heating, VLS, CVD and quenching tests. Set the furnace horizontally or at an angle to grow electronic crystals for semiconductor industry use or rotate it vertically for sintering applications.


Furnace Structure

  • Energy saving high purity Al2O3 fibrous insulation liner
  • Stainless steel shells with adjustable height
  • Adjust three knobs on the back to flexibly change the furnace's vertical position within travel distance (from control box platform to lower end of the chamber): 4.5'' ~ 12'' (without hanger and supporter) 
  • Multiple configurations for various thermal processing needs
      Multi-position adjustable         Using as a Vertical muffle furnace                   Fixing Knobs for Position Adjustment

Heating Elements

Fe-Cr-Al Alloy doped by Mo

Processing Tube

1" O.D x 0.87" I.D x 24" L Quartz tube or 2.0" O.D x 1.85" I.D  x 24" L quartz tube

(Please select the tube size and the rated voltage in the options bar
  • Two fibrous ceramic tube blocks are included for blocking heat radiation generated from tube center. (Ceramic blocks must be fully inserted into the furnace chamber before heating).
  • Quartz blocks (optional) are ideal for cleaner processing environment and higher vacuum efficiency.

Vacuum Flange


Two choices of stainless steel flange with vacuum gauge and valves
  • 2" default flange with 1/4'' Bard fittings, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum portclick bottom right picture to see details )
  • 1" flange has no thermocouple insert ( click bottom left picture to see details )

      1" Flange Set              2" Flange Set


Fitting Ports

  • Both flanges will come standard with 3/8" barbed hose fittings
  • In order to increase the throughput and achieve a high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter (please click the underline to order).
  • For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting x 1/4" BSPP Male Connector (please click the underline to order).        

Vacuum Pressure

  • 50 mtorr can be achieved by mechanical pump
  • 10^-5 torr can be reached by molecular pump

Pressure Measurement / Monitoring

  • Mechanical Vacuum Gauge (included as standard accessory), which measures within a pressure range of -0.1 to 0.15Mpa.  
  • Digital Pressure Gauge (optional): A gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces risks of chamber explosions caused by incorrect reading of gas pressures due to gas-type dependency
