Small tube furnace

· Rated power: 2.5KW

· Rated voltage: AC220V 50/60HZ

· Long-term use temperature: 1650℃

· Max use temperature: 1700℃ (≤0.5h)

· Recommended heating rate: below 1400℃: ≤10℃/min; 1400℃ to 1600℃: ≤5℃/min; after 1600℃: ≤2℃/min.

· Heating element: silicon molybdenum rod

· Thermocouple: Type B

· Heating zone length: 170mm

· Double-layer shell structure is adopted, and the double-layer furnace shell is equipped with an air cooling circulation system.

· The furnace adopts high-purity polycrystalline alumina fiber to greatly reduce energy loss.

· (Standard) OD: 60 mm x 800 mm L

· In order to ensure the uniformity of the temperature field and the sealing of the flange, alumina tube plugs need to be inserted at both ends of the furnace tube before the instrument is heated to prevent heat loss.

· Mini tube furnace includes a YD858P temperature controller;

· PID automatic temperature control system;

· Intelligent 50-segment programmable control;

· Built-in overheat protection and thermocouple fault alarm;

· Temperature control accuracy: ±1℃;

· Default DB9 PC communication connection port;

· Passed MET certification;

· Vacuum degree: 50mTorr (using mechanical pump)

· Mechanical pressure gauge measurement range: -0.1-0.15Mpa

· Furnace tube pressure limit: ≤0.02Mpa

· Various vacuum pumps can be selected in our company.

· This mini tube furnace has passed CE certification

Certificate number: M.2021.206.C67996

· If the customer pays for the certification fee, our company guarantees that a single device will pass the German TUV certification or CAS certification

One-year warranty, lifelong technical support.

Special note: 

1. Consumables such as heating elements, furnace tubes, sample crucibles, etc. are not included.

2. Damage caused by the use of corrosive gases and acidic gases is not covered by the warranty.

· The gas pressure in the furnace tube cannot be higher than 0.02MPa (relative air pressure);

· Due to the high pressure inside the gas cylinder, when the gas is introduced into the quartz tube, a pressure reducing valve must be installed on the gas cylinder. In order to ensure safety, it is recommended to use a pressure lower than 0.02MPa. 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, which will be more accurate and safe when used;

· For the experiment of sample heating, it is not recommended to close the exhaust valve and the air inlet valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you need to pay attention to the pressure gauge reading at all times. If the pressure reading is greater than 0.02MPa, you must immediately open the vent valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.).

· We do not recommend customers to use flammable, explosive and toxic gases. If customers really need to use flammable, explosive and toxic gases for process reasons, please take relevant protective and explosion-proof measures by yourself. The company is not responsible for any related problems caused by the use of flammable, explosive and toxic gases.

· The gas flow rate should be <200SCCM (200ml/min)

· Due to the manufacturing process of alumina tubes, there is a risk of tube breakage during the sintering process of the furnace tube, which cannot be completely avoided. Please be aware of this.
