Product Overview

Electric tube furnace PT D60/440/14 features single heaing zone, electric heated with Silicon Carbide Rods. Microprocessor-based self-tuning PID provides excellent control with no overshooting and +/- 1 °C accuracy. Max vacuum level could be reached to 10E-5 torr with molecular vacuum pump, it is widely used in vacuum and/or atmosphere protection sintering, including calcining inorganic compounds and/or preparing Li-Ion battery cathode powders with better uniformity in multiple gas controlled / CVD up to 1400°C. The electric tube furnace is an ideal tool for laboratory daily use.

Application Notes
  • Don’t fill any explosive gasses such as Hydrogen or Methane into the tubular furnace without necessary safety controls and supervision.
  • The 1400C Electric Tube furnace with alumina tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
