Application Notes

In order to obtain accurate temperature inside the tube furnace, you need to perform a temperature calibration before use, please click here to learn how.
Vacuum pressures may only be safely used up to 1500°C
The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 MPa (absolute pressure)
Attention: it is necessary to install the gas pressure regulator to reduce the output pressure 3 PSI, avoid overpressurizing the furnace chamber, and ensure safe operation. Click here to learn the installation of a gas regulator.
The flow rate for gases should be limited to < 200 ml/min) for reducing thermal shocks to the tube
Two fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube (Ceramic blocks must be fully inserted into the furnace chamber before heating).
