Furnace Structure

• Double layer steel structure with dual air cooling fans 
• One pair of sliding rails is installed on bottom of furnace, which allows furnace to be manually moved from side to side
• Vacuum flanges and a vacuum gauge are installed  for immediate use.

Power

1.5 KW

Voltage

Furnace: AC 208V~240V Single Phase, 50/60 Hz
Sliding Mechanism: AC 208V~240V Single Phase, 50/60 Hz

Max. Temperature

1200°C (<1 hour) with flowing gas

Continuous Temperature

1100°C

Heating& Cooling Rates 

Note: The max heating and cooling rate is achieved by pre-heat one side of processing tube to the target temperature and then slide the furnace to the other side. You may choose to place the sample in the pre-heat area or not.

Heating Zone Length

Constant Temperature Zone

2.3" (60mm)  (+/-1°C) @ 1000 °C

Heating Elements

Fe-Cr-Al Alloy doped by Mo

Processing Tube

• High purity fused quartz tube
• Size:  OD: 2" x  ID: 1.8." x Length: 39" (inch)   (50 mm OD x 46mm ID x 1000 mm L）
• Two foam ceramic blocks are included which must be placed inside tube to avoid heat radiation damaging the O-rings

Temperature Controller
& Sliding Control

• 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
• Built-in over temperature alarm and protection allows for operation without an attendant.
• K-type thermal couple is built in furnace to control furnace temperature
• Optional:  
• The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module and computer together with the furnace at extra cost.  We recommend you to order a computer (laptop) from us to avoid software installation problems.

•  

Compliance

• 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. 

Application Notes

• Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa
• Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. 
  
• The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
• Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C

• If you need faster cooling please click the picture below to order a  Portable Spot Air Cooling Conditioner .
• After CVD, the graphene must be transferred from the metal catalyst to another substrate for most applications. By using the graphene transfer tape, the residue can be low.
• For Horizontal directional crystalization  (HDC), you may use a gas feedtrough as pic below right.
•  

Warning

• Fast sample cooling can be achieved by sliding the heating chamber away. Please wear protective gears such as heat resistant suit & gloves if you intend to do so. 
• DO NOT TOUCH THE TUBE SURFACE WHEN IT IS HOT!
