OTF-1200X-50-SL is a compact automatic sliding tube furnace with 2" OD x 36" L Quartz tube and flanges with 1200°C max. working temperature. The automatic sliding mechanism allows the furnace to slide from one side to the other for achieving the max. heating and cooling rates of > 100°C/min.
For achieving the fastest heating, the furnace may be pre-heated to the desired temperature and then get slid to the sample's position. As for the fastest cooling, the furnace can be slid to another side after sample heating is completed. Moreover, the heating and cooling rates may reach 15°C/s under vacuum or inert gas conditions. This furnace provides an alternative for rapid thermal processing at the lowest cost.
SPECIFICATIONS:

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
- 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.
- The flow rate for gasses should be limited to < 200 SCCM 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
- Click here to learn How to set up quartz/ ceramic tube and vacuum flange for MTI Tube Furnace.
- If you need faster cooling please click the picture below to order a Portable Spot Air Cooling Conditioner.
- For Horizontal directional crystallization (HDC), you may use gas feedthrough as pic 2
- The furnace can be upgraded to 2 zone heating at an extra cost.(Pic. 3)
- For high and ultrahigh vacuum applications, select the optional turbo vacuum pump at extra cost. (Pic.4)

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!
