1200C Max. Ultrasonic Spray Pyrolysis 3-Zone Furnace for Nano Particles Synthesis - OTF-1200X-III-PGEP

0.0/5 rating (0 votes)

Description

OTF-1200X-PGEP is a versatile ultrasonic spray furnace system designed for nano, core-shell structured particle synthesis.  The system consists of three major modules: 1.7MHz ultrasonic enhanced bubbler, 1200ºC Max. 3 zone heating tube furnace, and Electrostatic Precipitator.   The processing steps of a particle includes aerosol generation, thermal decomposition, and nanopowder collection. Such a system enables advanced synthetic method that provides control over particle size, morphology, nano/microstructure.

SPECIFICATIONS

System Structure	Aerosol Generation: 1.7 MHz 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:  three-zone ( 900mm length ) tube furnace can be heated up to 1200C maximum to pass the droplets flux across the temperature and atmosphere regulated firing zone, chemical, and physical conversion processes proceed.   Nanopowder Collection: 30KV  electrostatic precipitator (700 ml ) can effectively collect nano-size particles from the carrier gas flow The furnace can be tilted to avoid liquid flow back  atomizing tank

Warranty		One-year limited manufacturer warranty with lifetime support (consumable parts such as furnace liner, processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below).
Laptop, software & WiFi Control (Optional)		Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013  Labview Based Temperature Control System (EQ-MTS01) enables the user to edit temperature profiles, manage heat-treatment recipes, record and plot data for MTI furnaces.
Compliance		CE Certified NRTL or CSA certification (UL61010) is available upon request at extra
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 the installation of a gas regulator.  Please tilt furnace in 10 - 15 degrees to avoid liquid back to atomizing bubbler It is the customer's responsibility to achieve the ideal parameter for particle size. Usually, the liquid injection rate and carrier gas flow rate has an important influence on particle size.
