Four Zones 1200oC Tube Furnace w/ Temperature Controllers for 1 or 2" Tube - OTF-1200X-IV-S

OTF-1200X-IV-S is the smallest 1100 o C Four- Zone split tube furnace with a separate temperature control console. Such a four-zone furnace can create a step thermal gradient or uniform temperature zone up to 10" long by adjusting the four zones' temperature. The furnace can accept 1-2” OD processing tube (with min. 1000mmL). Four digital temperature controller is built in a separable unit .  It is an excellent furnace for various CVD, and PVD applications.

Specifications

Furnace structure	Double layer steel case with air cooling keeps the furnace surface temperature lower than 60°C. Energy-saving high purity fibrous alumina insulation. Heating Element:1300C grade Fe-Cr-Al Alloy doped by Mo 400mm long heating chamber with built-in four high-quality thermal couples.  The furnace heating module can be positioned horizontally or vertically as shown in the images below (Note: customers are responsible for DIY the support frame/bracket in order to maintain its vertical position)

Operation Instruction	The tube furnaces with quartz/mullite tubes are designed for use under vacuum and low pressure <0.2 bars Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. Vacuum pressures may only be safely used up to 1000°C
