| 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

Compliance
 | - 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)
