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. 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

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 |
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. - • 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
|
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

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)
