In stock
Item Number: OTF-1200X-4-R-II-UL
Transported by LTL Freight (Truck)
OTF-1200X-4-R-II is a  two zones rotary tube furnace, designed for calcining inorganic compound with better uniformity, especially good for preparing Li-Ion battery cathode materials with conductive coatings, such as LiFePO3, LiMnNiO3, etc and rotating CVD for Si/C anode materials。
Specifications:


Furnace Construction

Warnings
  • The tube furnaces with quartz tube are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa
  • 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.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
