Product Options

by Voltage:

GSL-1100X-NT is a CE certified compact tube furnace (1~2" diameter) designed for firing small samples up to 1100oC. Built-in precision temperature controller can program up to 30 segments of heating rate, dwell time and cooling rate. The furnace can be set up in both vertical and horizontal positions to meet various applications such as firing sample, VLS, CVD and quenching test. Set the furnace horizontally or at an angle to grow electronic crystals for semiconductor industry use or rotate it vertically for sintering applications.

This version does not include the Stainless steel vacuum flanges with valves, vacuum pressure gauge and quartz tube. To order the furnace with these components together, please click here.


Furnace Structure

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

Heating Elements
Fe-Cr-Al Alloy doped by Mo
Processing Tube (Sold Separately) & Tube Adapter
Two choices of quartz tubes: 25 ODx22 IDx 450 L (mm) quartz tube or 50 ODx44 IDx 450 L (mm) quartz tube (Please find in related products)
  • The furnace chamber is designed to adopt 2" O.D quartz tube, we also include a 2''-1" tube adaptor which allows the 1'' O.D tube be fit on the furnace.
  • Fibrous ceramic tube blocks can be used 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 (Sold Separately)
Two choices of stainless steel flanges with vacuum gauge and valves


Fitting Ports (Sold Separately)

  • 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 theKF25 adapter (please click the underline to order).
