Furnace w/ 1.7MHz Ultrasonic Spraying up to 1800C for Special-Particle Formation - GSL-1800X-PGEP

Please email for lead time
Item Number: GSL-1800X-PGEP


GSL-1800X-PGEP is a versatile synthetic system designed for nanostructured oxide materials. Three major modules (Ultrasonic Enhanced Bubbler, Tube Furnace, and Electrostatic Precipitator) are employed on three processing steps including aerosol generation, thermal decomposition, and nanopowder collection. Such a system enables an advanced synthetic method that provides control over particle size, morphology, and 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 connected in line with the ultrasonic bubble can prevent condensing liquid from streaming into the furnace tube chamber. 
  • Thermal Decomposition: Tube Furnace can be heated up to 1800C maximum. Bypassing the droplets flux across the temperature and atmosphere-regulated firing zone, chemical, and physical conversion processes proceed.  
  • Nanopowder Collection: 50KV, 2'' O.D tubular designed electrostatic precipitator (1.2L)can effectively collect nano-size particles from the carrier gas flow

  • 1200oC, 1500oC, 1700oC furnace is available at lower cost
Max. Heating / Cooling Rate
5oC / min ( T< 1600oC ); 2oC / min ( T>1600oC )
Heating Zone & Constant Temperature Zone
  • 12" total heating zone length
  • 3" ( +/- 1 oC )  constant heating zone
Heating Elements
Temperature controller
  • Eurotherm 3000 Series Programmable Temperature Controller.
  • 1 program, 24 segments programmed with ramping, cooling and dwelling steps
  • Temperature Accuracy:  ±  0.1ºC
Laptop & software (Optional)
  • Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use.
  • Labview-Based Temperature Control System enables the user to edit temperature profiles and manage heat-treatment recipes for MTI furnaces.
  • Note: Due to the complexity of the controller operation, we strongly suggest customers purchase this PC control kit along with the furnace and our engineers will have the software & hardware pre-installed. 
Processing Tube
  • Premier grade high purity Al2O3 ceramic tube is included for operation @ 1500C~1800C. (I.D: 44mm x OD: 50 mm x 1200 mm length). Attention: carrier gas flow rate should be strictly controlled @ 100SCCM or less.
  • Mullite tube (I.D: 44mm x OD: 50 mm x 1398 mm length) is included for continuous operation up to 1500C. Benefits from its high thermal shock resistivity, it can endure a max. carrier gas flows rate @ 200SCCM.
Sealing Flanges
& Fittings
  • Left sealing flange with 1/4'' feedthrough, needle valve, and mechanical pressure gauge. A 1/4'' O.D x 17'' L alumina tube is inserted into the main chamber. It can deliver the aerosol to the hot zone directly. 
  • Right KF50 quick disconnect flange provides direct coupling for the electrostatic precipitator. 
Aerosol Generation Ultrasonic Enhanced Bubbler

  • 220VAC, 1.7 MHz Ultrasonic Generator
  • Fluoropolymer coated liquid container and Fluoropolymer sealing gaskets
  • In-situ optical sensor and valve for keeping the liquid level to the correct height and preventing damage to the nebulizing element
  • Ultrasonic power programmable,0~100%, 5% increment.
Mass Flow Controller

  • An MFC is employed to control the carrier gas flow rate. It is very important that the gas flow must be controlled <100SCCM in order to minimize the thermal shock impact on the furnace tube. 
Condensing Liquid Collector

  • 316 stainless steel made container, 150ml
  • Two SS needle valves with 1/4" Tube Fittings
  • The cap is attached to the body with a quick disconnect clamp. This allows for easy removal of components for cleaning
Nanopowder Collection
High Voltage Supply

  • 208~240VAC Single Phase, 15W max.
  • Digital Voltmeter and Current meter, 50KV, 0.5mA max.
  • Output voltage and current can be set by using knobs on the front panel and read from the digital display
  • Constant current/Constant Voltage mode of operation
  • Built-in Arc Protection Circuit
Tubular Electrostatic Precipitator
  • Negative charged circular mesh plate and Positive charged 1'' O.D x 170mmL Al tube collector are built into a transparent 2'' O.D x 450mm L-quartz tube
  • The use of KF50 quick clamp and flange enables the quick coupling to the furnace processing tube
  • Adjustable balance supports keep the collector leveled with the furnace tube

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).
  • CE Certified
  • NRTL (UL61010)  or CSA certification is available at extra cost. 
Application Notes

  • Never use graphite crucible in the alumina tube.
  • 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 heat
  • The flow rate for gases should be limited to < 100 SCCM (alumina tube); <200SCCM (mullite tube)
