Specific Introduction:
KJ-1200X-10-VT is a ten-temperature zone vertical/horizontal dual-purpose open tube furnace, equipped with Φ100*2000mm quartz tube and quick-opening sealing flange, the maximum temperature of the furnace body can reach 1200℃ . The heating element is a resistance wire, and each temperature zone is controlled by an independent temperature control system, which can form a variety of temperature gradients in the furnace tube. At the same time, the furnace body can be manually changed to a vertical furnace to realize the sample in a vacuum or atmosphere protection environment The hanging firing and quenching can meet various experimental requirements. Such as the preparation of functionally gradient materials, the preparation of materials by high-throughput CVD method, the study of phase change, and so on.

Parameters:

Furnace Structure	Double layer steel case with air cooling to ensure max. energy saving and furnace surface temperature < 60 °C. Heating Element: 1300ºC grade Fe-Cr-Al Alloy doped by Mo. 10 heating zones (120 mm L each) with 10 thermal couples & temp. controllers to create a various thermal gradient. Accept processing tube from 1" - 4 " dia. x 2000 mm length. Split Cover for easy processing tube exchanging. Quick clamped vacuum flange for atmosphere control. The furnace can be in the position either horizontal or vertical.
Working Temperature	1200 °C Max. for < 1 hour under flowing gas. 1100 °C under flowing gas. 1000 °C under vacuum < 1 torr.
Max. Heating Rate	≤10 °C /min
Quartz tube & Thermal Block Placement	Quartz Tube: 100 OD x 96 ID x 2000 L mm. Two fibrous alumina thermal blocks are included, which must be placed on two ends of inside tube.
Vacuum Flange	One pair stainless steel vacuum flange is included with quick assembling flange (a outside clamp for quick installation) Left flange installed with needle valve with 1/4" pipe port for gas inlet (Pic below left). Righ flange built in K25 port and Anti-Corrosive digital vacuum gauge to connect a vacuum pump.
Vaccum Level	5x10-3 torr by mechanical vacuum pump 5x10-4 torr by turbo pump Vacuum pump is not included
Heating Zone	Ten independent heating zones: each heating zone length 120 mm with 30 width separator. Total zone length: 1570 mm . Max. Constant temperature zone 1000 mm ) if 7 zones heated at same temperature ( within ± 2 °C).
Temperature Controllers	10 digital temperature controllers are built-in to control each heating zone independently with 30 segments programmable ±1 ºC temperature accuracy. 10 pcs N type thermocouples (one for each zone). RS485 Communications Port built in. and software included
Options	You may add a multi-channel gas delivery system for CVD or atmosphere control applications You may consider a pressure control unit to keep constant pressure
Warranty	One-year limited warranty for electrical parts. (Consumable parts such as processing tubes, o-rings, and heating elements are not covered by the warranty, please order the replacement at related products page)
Warning	The tube furnaces with quartz/mullite tube are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa. Attention: A two stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation. Vacuum pressures may only be safely used up to 1000°C . The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube.
