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 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
- 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
|
Electrostatic Precipitator
 
|
- Up to 30 kV and 1 mA.
- A KF25 quick clamp and flange enables the quick coupling to the furnace processing tube.
- Another KF25 port is built-in with the collector to connect the vacuum pump (The vacuum pump is required, but it is not included in the standard package.)
- PTFE plates are installed on top and bottom to insulate high-voltage electrodes
- 12mm gas outlet built-in.
- The electrode rod is in the shape of a cross, increasing surface area compared to cylindrical electrodes.
- Adjustable supports keep the collector leveled with the furnace tub.
- Double layer design (optional) please check the picture shown on the left.
