1100℃ Multi-station tube furnace



KJ-1100X-S is a small-bore tube furnace (1~2" diameter) that has passed CE certification. It is specially designed for preparing small samples. The maximum temperature can reach 1100℃.

Specific Introduction:
    KJ-1100X-S is a small-bore tube furnace (1~2" diameter) that has passed CE certification. It is specially designed for preparing small samples. The maximum temperature can reach 1100℃. The standard includes a stainless steel sealing flange. With the quartz tube, the customer can use it immediately after turning on the power. The 30-segment programmable precision temperature controller can set the temperature rise and fall program according to different customer needs. The temperature control accuracy is ±1℃. The furnace body can be placed vertically or horizontally. Meet different applications, such as VSL, CVD, and other quenching tests.


The main parameters ·Maximum temperature: 1100℃ (less than 30min)

Euro instrument ·European type temperature control instrument can be purchased, and the temperature control accuracy can be increased to ±0.1℃.
·For specific details, please call our sales company.
Heating element Mo-doped iron chromium aluminum alloy
Flange and optional accessories ·Two kinds of stainless steel flanges are available:
· 2" default flange, with 1/4" pagoda nozzle connector, 1/4" pipe through hole (for 1/4" outer diameter thermocouple plug-in) and KF25 vacuum connection
· 1" flange without thermocouple plug
· Optional:
·You can purchase a flapper valve to connect to the vacuum system
·In order to obtain faster and better vacuum, we recommend using stainless steel bellows
·You can consider ordering quick connection flanges, but additional charges are required
·Furnaces with digital display vacuum gauge and mechanical pump system can be ordered
Seal flange and vacuum connection ·Stainless steel sealing flange (the air inlet at the left end is a 1/4" hose interface, and the air outlet at the right end is a KF-25 interface)
·Standard 1/4" pagoda mouth interface with needle valve
·In order to be able to use high-pressure gas, you can replace the standard pagoda nozzle pipe joint with a 1/4" hose joint
·Optional: In order to achieve high vacuum, KF25 adapter can be used to replace the standard pagoda nozzle connector
·Optional vacuum connection:
·The anti-corrosion digital vacuum indicator imported by our company has a measuring range of 3.8x10-5 to 1125 Torr. There is no need for coefficient conversion due to different gas types.
·KF25 stainless steel bellows
·KF25 fast loading and unloading clamp
Vacuum system Including double rotary vane mechanical pump (220V, 226 L/m) oil mist filter & KF-D25 stainless steel vacuum bellows and KF25 clamp
The vacuum degree can reach 1E-2 Torr (50 m-torr)
·Molecular pump: 1E-5 Torr
Pressure measurement/detection Mechanical pressure gauge, measuring pressure range is -0.1 to 0.15Mpa.
·The anti-corrosion digital vacuum indicator imported by our company (optional), its measuring range is 3.8x10-5 to 1125 Torr. No need for coefficient conversion due to different gas types
Dimensions Dimensions: 260×380×400 mm (D x H x W)
Furnace size: 80X330
Net weight 45Kg
Certification ·All electrical components (>24V) have passed UL/MET/CSA/CE certification. If the customer pays the certification fee, the company guarantees that a single device has passed the German TUV certification or CAS certification.
Warranty One year warranty and lifetime technical support.
Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included.
2. Damage caused by the use of corrosive gas and acid gas is not covered by the warranty.
Related applications This equipment can be designed as a swing furnace
Application note ·The pressure in the furnace tube should not be higher than 0.02MPa
·Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when passing gas into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company’s pressure reducing valve is 0.01MPa-0.1MPa , It will be more precise and safe to use
·When the temperature of the furnace body is higher than 1000℃, the furnace tube must not be in a vacuum state, and the air pressure in the furnace tube must be equal to the atmospheric pressure and keep it at normal pressure.
·The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heated quartz tube
