Specific Introduction:
KJ-1800X 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.
Parameters:

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
Tube Furnace - Thermal Decomposition		Voltage & Power	Single Phase, 208V~240V AC, 50/60 Hz (30A breaker required) MWax. 2.5 K

		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	4 pcs Kanthal 1900ºC grade MoSi2 heating elements
		Temperature controller	Eurotherm 3000 Series Programmable Temperature Controller. 1 program, 24 segments programmed with ramping, cooling and dwelling steps Temperature Accuracy: ± 0.1ºC
		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

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 at related products page).
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. 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)
