Product Options
Tube size and voltage:
GSL-1100X  is a CE certified small quartz tube furnace (1~2" diameter) and  is designed for firing small sample up to 1100oC. Stainless steel vacuum flange with valves and vacuum gauge and quartz tube are included for immediate use. Built in precision temperature controller can program heating rate, dwell time and cooling rate up to 30 segments.  The furnace can be set up in both vertical and horizontal position to meet various applications such as firing sample, VSL or CVD and quenching test.


 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 option bar)
Two fiberous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
Quartz block (Optional) is ideal for more cleaness and higher vacuum.
