1.7MHz Ultrasonic Spray Pyrolysis Furnace 1200C Max. for Synthesis Nanoparticles - OTF-1200X-PGEP
|
Please email for lead time
Item Number: OTF-1200X-PGEP
Personalization
Upgrade to Eurotherm 3000 series
|
OTF-1200X-PGEP is a versatile ultrasonic spray furnace system designed for the synthesis of core-shell nanoparticles. Three major subsystems (ultrasonic enhanced aerosol generator, tube furnace, and electrostatic precipitator) are employed on three processes including aerosol generation, thermal decomposition, and nanoparticle collection. Such a system enables advanced synthetic method that provides control over particle size, morphology, and nano/microstructure.
SPECIFICATIONS
System Features
|
- Aerosol Generation: 1.7MHz Ultrasonic Enhanced Bubbler can "evaporate" target solution with literally no heat generated. An elongated Tee tube wrapped by a heating tape that connects inline with an ultrasonic bubbler can prevent condensing liquid from streaming into the tube furnace and promote the generation of aerosol.
- Thermal Decomposition: The tube Furnace can be heated up to 1200C maximum. By passing the aerosol flux across the temperature and flow rate-regulated firing zone, chemical and physical processes may proceed.
- Nanopowder Collection: an electrostatic precipitator (1.2 L, up to 30 kV) can effectively collect nanoparticles from the carrier gas flow

Ultrasonic Generator
|
- 316 Stainless Steel liquid container equipped with a fluoropolymer sealing ring and a heating tape
- 1.7 MHz ultrasonic generator installed with a PEEK base
- 3 levels of power output ( low = "1", liquid injection speed = 0.2 mL/min), (middle = "2", liquid injection speed = 0.4 mL/min), (high ="3", liquid injection speed = 0.6 mL/min). To achieve high atomizing quality, the syringe pump rate should be match with the power output level.
- 7 levels of time setting ("Out" indicator light), "1" = no limited timing, "2" = 30 min, "3"= 60 min, "4"= 90 min, "5"= 120 min, "6"= 150 min, "7" = 180 min
- Droplet size: < 10 microns, which is dependent on the viscosity of the solution, ultrasonic frequency, and gas speed.
- Continuous mode and timed mode can be set.
- The quick clamps allow easy removal of components for cleaning or adapting the device with simple connections to the gas supply
|
Digital Syringe Pump
|
- Holds small or big syringes up to 60 mL
- Pumps continuously until you stop the pump
- The infusion rate can be changed while pumping
- Remembers previous settings on power-up
- Power failure mode allows the pump to continue pumping after a reset
- The maximum pumping rate of 25 mL/min with a 60 mL syringe
- Selectable infusion rates units: mL/hr, µL/hr, mL/min, µL/min
- Infuses Only does not withdraw, volume target, or have a computer interface
- An infusion Syringe Pump with an optional Heatable Glass Syringe is available at an extra cost
|
Flow Meter
|
- A 0-1000 ml/min floating flow meter is included to control the carrier gas flow rate.
- The mass flow meter is optional at an extra cost. (EQ-MFC-GFC-LD)
|
Nanopowder Collection |
|
- 24VDC input high voltage power supply up to 30KV, 30 W Max. power consumption
- Digital Voltmeter and Current meter

Application Notes
|
- 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 about the installation of a gas regulator.
- Never heat the furnace while the gas 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.
- Wrapping Aluminum foil to achieve better thermal conductivity.
