UL Standard 1200°C Split Tube Furnace with Vacuum Flanges & Optional Quartz Tube 60, 70, 80 or 100 mm O.D -OTF-1200X-UL

0.0/5 rating (0 votes)

Description

Product Number: OTF-1200X-UL

 

OTF-1200X-UL furnace is configured to meet UL/CSA certificate standard. The furnace can adopt a 60, 70, 80 or 100mm O.D quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge allow heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high precision digital controller which provides 30 programmable segments with +/- 1°C accuracy. The maximum working temperature is 1200°C.  


SPECIFICATIONS:

Furnace Structure
  • Double layer steel casing with air cooling keeps furnace surface temperature lower than 60°C.  
  • High purity fibrous alumina insulation for maximum energy saving.
  • Special refractory coating on liner and heating element to increase furnace life.
  • All electric components are UL or Met recognized and ready to pass any safety test worldwide
Power 3KW
Input Voltage 208 - 240VAC SINGLE PHASE, 50/60Hz

Heating Temperature
  • Max. heating temperature: 1200°C (N2 or other inert gas must be filled inside the tube to resist deformation)
  • Continuously heating temperature: 1100°C
  • Heating rate: 20°C /min Max.

Vacuum Sealing


 
  • One pair of SS 304 vacuum flange with double high temperature silicone O-ring is Included. Left flange is built in 1/4" OD thermal feedthrough port for temperature calibration at easy ( click PiC, below left-2 for detail)
  • Two needle valves are installed on flanges.
  • Default flange with 1/4'' Bard fittings, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum portclick bottom left picture to see details )
  • One vacuum/ pressure gauge is installed on one side of flange. ( see Pic below left )
  • Vacuum level can reach 10E-2 torr by quality mechanical vacuum pump and 10-5 torr by molecular 
         
Note: The standard vacuum flange for 70mm O.D tube doesn't have KF-25 port or thermocouple feedthrough. Click there to see detail pic.  




Refractory Blocks
  • 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 blocks (optional) are ideal for cleaner processing enviroment and higher vacuum efficiency.

Application Notes


Click here to learn the installation of a gas regulator
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • 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.
  • Heating module is consumable.  Please click picture below-right to order replacement.
  • The furnace with Sliding flange is vailable
