Tube Furnace with 2.4MHz Ultrasonic Spraying and Electrostatic Precipitator upto 1800°C for Special -Particle Formation - GSL-1800X-PGEP

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


Upgrade to Eurotherm Temp. Controller
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 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 1800C maximum. By passing the droplets flux across the temperature and atmosphere regulated firing zone, chemical, and physical conversion processes proceed.  
  • Nanopowder Collection: 30KV, 2'' O.D tubular designed electrostatic precipitator 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

  • PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.
  • 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Built-in over temperature alarm and protection allows for operation without the attendant.
  • +/- 1 ºC temperature accuracy.
  • RS485 Communication Port.
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. Water cooling feature can be added with additional fee applied.
Aerosol Generation Utrasonic Enhanced Bubbler

  • 110VAC, 2.4 MHz Ultrasonic Generator
  • Fluoropolymer coated liquid container and Fluoropolymer sealing gaskets
  • external Fluoropolymer optical sensor and valve for keeping the liquid level to the correct height and preventing damage to the nebulizing element, should the unit run dry.
  • Ultrasonic power programmable,0~100%, 5% increment.
  • 304 Stainless Steel T-piece (1.5'' sanitary fitting) with 1/4'' tube fitting adapters enables the use of carrier gas.
Mass Flow Controller

  • A 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 quick disconnect clamp. This allows easy removal of components for cleaning
Nanopowder Collection
High Voltage Supply
  • 208~240VAC Single Phase, 15W max.
  • Digital Voltmeter and Current meter, 30KV, 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
  • Negtive 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

  • 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 
  • Never use graphite crucible in 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 heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
  • The flow rate for gases should be limited to < 100 SCCM (alumina tube); <200SCCM (mullite tube)
