1200°C Ultrasonic Spray Pyrolysis Vertical Furnace (5'' O.D Tube) with "Wet" Scrubber for Core-Shell/Nano Particles Synthesis - OTF-1200X-S5-PGEP

Please email for lead time
Item Number: OTF-1200X-S5-PGEP


Upgrade to Eurotherm Temperature controller + USB-to-RS485 cable
OTF-1200X-S5-PGEP is a verticle 5'' ultrasonic spray pyrolysis tube furnace designed for nano, core-shell structured particle synthesis. Three major modules (Ultrasonic Enhanced Bubbler, Tube Furnace, and wet scrubber) are employed on three processing steps including aerosol generation, thermal decomposition, and nanopowder collection. Such a system enables advanced synthetic method that provides control over particle size, morphology, nano/microstructure.

System Structure
  • Aerosol Generation: 2.4MHz Ultrasonic Enhanced Bubbler can "evaporate" catalyst liquid with literally no heat generated. A stainless steel liquid collector connects inline with the ultrasonic bubble can prevent condensing liquid from streaming into the furnace tube chamber. 
  • Thermal Decomposition: Tube Furnace can be heated up to 1200C maximum. By passing the droplets flux across the temperature and atmosphere regulated firing zone, chemical, and physical conversion processes proceed.  
  • Nanopowder Collection: 1000ml wet precipitator can effectively collect nano size particles from the carrier gas flow

  • The furnace is ready to pass TUV(UL61010)  or CSA certification at extra cost. ( please click marks below to learn details )
Application Notes

  • The system with alumina tube is designed for using under 1ATM 
  • 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.
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
