Dual Zone Quartz Tube Furnace (80mm Dia, 1200C Max) with 3-Ch Gas Mixer, Vacuum Pump, & Anti-Corrosive Vacuum Gauge - OTF-1200X-II-F3LV

• Double layer steel casing with air cooling. 
• Built-in thermostat automatically runs the cooling system when the case temp.  > 55°C.

Power Consumption

2.5 KW

Input Voltage

AC 208-240V Single Phase, 50 or 60 Hz 

• If two zones are set at the same temperature, constant temperature zone is 10" (250 mm) long with a temperature discrepancy of +/- 1°C.
• If using only one zone (center zone), constant temperature zone is 4.3" (110 mm) long with a temperature discrepancy of +/- 1°C.

Temperature Controllers

Tube Size and Materials

Quartz Tube: 80 OD x 72 ID x 1000 L

Digital Vacuum Gauge 

• Corrosion-proof Capacitance Diaphragm Gauge with ceramic coated sensor head specially designed for vacuum measurements with the presence of corrosive gases.
• Gauge is installed on the vacuum flange (right side) of tube furnace and provides a wide measure range (10^^-5 ~ 1000 torr)
• Optional: click the pic below to order Constant temperature control module.
  

                

• Two stainless steel flanges with KF25 port, vacuum gauge and valves included.
• Min. vacuum pressure achieved by a mechanical pump is 5.5 m-torr. (5.5x10^^-3 torr). The pressure can reach 10^^-5 torr using mechanical + molecular pumps.
• Leaking rate is < 5 m-torr/min and stable vacuum pressure after 24 hours is < 2 torr.
• Click the picture below to get details of both charts and data measured by CE certified vacuum meter: 

  

Note: For the 24 hours curve display the time segment through 08:00:00~21:10:00 in X-axis is skipped over in the chart; therefore, a steep variance is present.

An Oxygen Sensor can be used to monitor the oxygen level of gas(es) used in CVD systems for preventing or reducing oxidation at extra cost. Please click the picture below to learn more:
        

Option: For precise control of the vacuum pressure, we recommend you choose our turn-key solution EQ-VPC-MV. This is a vacuum pressure regulating system with motorized valve and gauge. It controls pressure range from 10^-6 torr ~ 760 torr.

Gas Mixing Control Station

• Three gas flow-meters (4% accuracy FS) are installed inside the mobile case to enable monitoring of gas flowing rates (three different kinds of gases in total).

• Four pressure meters are installed inside the mobile cart which is able to monitor three types of flowing gas pressure as well as the pressure of mixing tank.

Dimensions

• Furnace: 550 x 380 x 520 mm 
• Bottom Mobile case: 600 x 600 x 597 mm Each

• Please click here to see our typical temperature profile calibration result at various temperature.
• From 7/15/08, MTI calibrates each furnace by NIST certificated Omega CL3515R precision Temperature calibrator, and pre-set temperature off (SC value) in the controller before shipping.
• In order to obtain accurate temperature inside the tube furnace, you need to calibrate temperature by yourselves. Please click here to learn how.
• How to set up a ceramic tube and vacuum flange for MTI Tube Furnace.
• Tube furnaces with alumina tubes are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
• The flow rate for gases should be limited to < 200 SCCM (or 200 ml/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.
• Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
