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

- If you need faster cooling please click the picture below to order a Portable Spot Air Cooling Conditioner.
- For Horizontaldirectional 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 for 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!
