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


In stock
Item Number: GSL-1500X-RTP50
Transported by LTL Freight (Truck)

Personalization

GSL-1500X-50RTP is a CE certified slideable tube furnace that utilizes 50 mm OD x 44mm ID x304.8 mm (12") L  mullite or quartz tubes (one end closed). The maximum working temperature of this furnace is 1500ºC.  A sliding rail is installed on right side of the flange for manually moving it from one side to the other, which allows it to achieve fast heating and cooling up to 1500 oC.  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 gasses. It is an ideal furnace for rapid thermal processing at the lowest cost.

  • To get the fast heating performance, first keep the tube out of the chamber meanwhile, preheat 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.
  • The tube furnaces with processing tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI.Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.  
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
  • The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
  • NOTE The mullite tube shall be considered as a consumable part. We strongly recommend user keep spare tubes in order to ensure the continuity of operation. The tube is not covered by Warranty. Use the link to order more. 
  • Please wear protective gears, such as heat resistant suit & gloves, if you intend to retract the tube from the heating chamber. DO NOT TOUCH THE TUBE SURFACE WHEN IT IS HOT!

& Demo  Video
   
Application note You may modify the RTP furnace into a small RTE ( rapid thermal evaporation ) or HPCV ( hybrid physical & chemical vapor deposition ) by DIY. please click the picture below to see how: 
Attention Notes Performance degradation (i.e. furnace can not reach the maximum temperature 1500°C or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen.
