1200C Split Tube Furnace with Optional Quartz Tube 60, 70, 80, or 100 mm O.D. & Flange - OTF-1200X series

OTF-1200X-UL furnace is configurated 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 max. 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. The special refractory coating on liner and heating element to increase furnace life. Split cover with Interlock protection, cut the power if the door open during furnace heating process.
Voltage and Power	Input voltage 208 - 240VAC Single Phase, 50/60Hz 3KW, Circuit breaker 20A 3KW, Circuit breaker 20A
Heating Temperature	Fe-Cr-Al Alloy doped by Mo Max. heating temperature: 1200°C ( inert gas must be filled inside the tube to resist deformation) Vacuum heating temperature: 1000°C under vacuum Heating rate: 20°C /min Ma Thermal Couples: K type 220mm (8.7") Length with Ceramic Sheath, please click the link to order spare.
Heating Zone	Total heating zone length: 440mm (~ 18") Constant temperature zone: 150mm (+/1°C) Please click the image below to view the temperature distribution at 980°C.       Temperature Distribution
Temperature Controller	The FA-YD518P-AG temperature controller is included. Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed with ramping, cooling and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm +/- 1 ºC temperature control accuracy Default DB9 PC communication port The software for PC software is included
Temperature controller (optional)	You may upgrade the temperature controller to the Eurotherm 300 Temperature Controller with +/- 0.1oC accuracy.  This package includes a Eurotherm 3204 programmer, a communication cable (RS485 - USB), and a software CD. Click the pic below to view the full specs

Refractory Blocks	Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) Quartz blocks (optional) are ideal for a cleaner processing and higher vacuum efficiency. You may order flange support to avoid tube rotating ( click Pic below right )
Vacuum Flange	One pair of SS 304 vacuum flange is included Left flange: one thermal feedthrough (for 1/4O.D sheathed thermocouple) one needle valve one mechanical vacuum gauge -0.1Mpa to 0.15Mpa one barb fitting ( click PiC, below left-2 for detail) Right flange: one KF-25 vacuum port and one needle valve. Optional An anti-Corrosive gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr is optional. Aside from greater measurement precision, this gauge reduces the risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency. The flange with quartz window is available for in-situ Raman or Mossbauer analysis
Vacuum Pressure	10E-2 torr by a quality mechanical vacuum pump  10E-5 torr by the turbopump. The vacuum pump is optional. Please click here to choose a vacuum pump.

Application Notes Click here to learn the installation of a gas regulator	Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gasses should be limited to<200 SCCM (or 200ml/min) The heating module is consumable.  Please click picture 1cto order a replacement. The automatic vacuum-sealed sliding device is available for fast heating and cooling  ( Pic. 2)    Pic. 1Pic. 2
