OTF-1200X-80-SL is a slideable tube furnace with 3" IDx55" L Quartz tube and flanges and a maximum working temperature up to 1200°C. One pair of sliding rails is installed on the bottom of the furnace to allow sliding the furnace from one side to another to achieve max. heating and cooling rates up to 100°C/min. For the fastest healing, the furnace may be pre-heated to the desired temperature and then be slide to the sample's position. As for fastest cooling, the furnace can be slide to another side after sample heating is completed. Moreover, the heating and cooling rates may reach 15°C/s under vacuum or inert gasses. This furnace provides an alternative for rapid thermal processing at the lowest cost.

Temperature Controller |
- PID automatic control with 30 programmable segments with +/ - 1°C accuracy
- Built-in over-temperature alarm and protection allow for operation without an attendant.
- Two K-type thermal couples are included. One is built in the furnace to control furnace temperature, and another inserted into the tube to monitor sample real temperature profile.
- One NIST certified thermometer is included to connect to the thermal couple inside the tube. the meter has RS485 Interface with Windows Software which can record temperature profile by PC.
-
PC control module is included.
- Advanced Temperature Control (Optional)
|
Vacuum Flanges |
- Stainless steel vacuum flanges are installed on both ends of the tube with heavy duty support.
-
Right flange: flange, fittings for the vacuum gauge are included. The bellow, KF25 adapter, KF25 clamp are not included.
- Left flange: one needle valve and 1/4" thermocouple feed-through and digital vacuum gauge.
-
An 24" length x 1/4" Dia. K-type thermocouple (included) connected to an Omega temperature calibrator (included) will be inserted through this flange to monitor the heating and cooling rates of the sample's position during furnace sliding.
