HTTF-1200-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.
Aerosol Generation Ultrasonic Spray Pyrolysis Furnace: 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 in line 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.
Nano powder Collection: an electrostatic precipitator (1.2 L, up to 30 kV) can effectively collect nanoparticles from the carrier gas flow.
Tube Furnace Thermal Decomposition | Voltage & Power | Single Phase, 208V~240V AC, 50/60 Hz (30A breaker required) Max. 3 kW |
Working Temperature | 1100°C continuous 1200°C Max. < 1 hour | |
Max. Heating / Cooling Rate | < 20 °C / min | |
Heating Zone & Temperature Uniformity | 12" total heating zone length 3" ( ± 1 °C ) heating area with the best thermal uniformity. | |
Heating Elements | Fe-Cr-Al Alloy doped by Mo | |
Temperature Controller | PID automatic control, 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Built-in over-temperature alarm and protection allow for operation without the attendant. ± 1 ºC temperature control at dwelling process RS485 Communication Port. | |
Processing Tube | The high-quality fused quartz tube is included for operation @ 1200C. (I.D.: 21mm x OD: 25mm x 1200 mm length). | |
Flanges & Fittings | Left flange: KF25 quick-connect Right flange: KF25 quick-connect | |
Aerosol Generation | 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. | |

Electrostatic Precipitator | Up to 30 kV and 1 mA. The use of KF25 enables the quick coupling to the furnace processing tube Adjustable supports keep the collector leveled with the furnace tube | |
Net Weight | 180Kg | |
Shipping Dimension & Weight | 48"x40"x62" 500 lbs | |
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 for related products below). | |
Laptop, software & WiFi Control (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, manage heat-treatment recipes, and record and plot data for HT Tube furnaces. A wireless remote control provides up to 300 meters of operating range. The above features are available upon request at an extra cost (up to $1,000). Please contact us for more information | |
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. 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. | |
