1500°C Max Tube Furnace (50mm OD) with Sliding Flanges for Fast Heating/Cooling - GSL-1500X-RTP50

0.0/5 rating (0 votes)


Item Number: GSL-1500X-RTP50

GSL-1500X-50RTP is a CE certified slide-able tube furnace that utilizes 44mm ID x304.8 mm (12") L  mullite or quartz tubes (one end closed). The maximum working temperature for this furnace is 1500ºC. One pair of sliding rail is installed on bottom of furnace for manually moving it from one side to the other. Sliding this furnace allows it to achieve fast heating and cooling (details in the chart below). For the fastest heating, you can insert a mullite processing tube into the pre-heated furnace at the desired temperature. For the fast cooling, you can remove the tube from the hot furnace chamber and use forced air cooling. The heating and cooling rates can be much higher under vacuum or inert gases. It is ideal furnace for rapid thermal processing at the lowest cost.


Furnace Structure
  • One sliding flange is installed on right side furnace, which can move processing tube in & out easily.
  • Vacuum flanges can reach 10E-5 torr by molecular pump or 10E-3 torr by mechanical pump.  The flange has a 1/4" dia. thermal couple built in for monitoring real time temperature inside tube.
  • RS485 port included for computerized control

Application Notes
  • To get the fast heating preformance, first keep the tube out of the chamber meanwhile pre-heat the chamber to the required temperature. Then insert the tube into the chamber to get fast heat. Please watch the demo video below to see how this is done.
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.12 MPa (absolute pressure).
Operation Instructions


In order to achieve a vacuum level of 10^-5 torr, we strongly suggest you to use a turbomolecular pump, KF25 adapter with stain steel vacuum pipe. Please order upgraded accessories from the table below:
