Control Panel One button operation - the diaphragm pump and the turbo molecular pump will start after pressing "start" button.
System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber.
Self protection - the system will protect the pump from damage by overheating and over-current if the leaking rate of the reaction chamber is too high to achieve high vacuum.
LCD screen - double lines parameters checking interface make the working easier to be handled.

Application Notes
Warranty One year limited warranty (Consumable parts such as processing tubes, o-rings and heating elements are not covered by the warranty, please order the replacements at related products below.)
  • CE Certified
  • All electric components ( >24V) are UL / MET / CSA certified
  • The furnace is ready to pass TUV(UL61010) or CSA certification at extra cost. (please click marks below to learn details)
Shipping Dimensions Two cases in one plastic pallet: 45x45x35/case

Click here to learn more about the installation of a gas regulator.
  • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
  • Attention: A two stage pressure regulator must be installed on 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 gases should be limited to < 200 SCCM ( or 200ml/min )
  • Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
