Introduction of split tube furnace:
Split tube furnace OTF-1200X-III is a three-temperature zone open tube furnace. The Max high operating temperature of split tube furnace can reach 1200℃ (1200℃<1h). The furnace tube of split tube furnace is a high-purity quartz tube. Split tube furnace is equipped with a pair of stainless steel sealing flanges, which can heat treat samples in a vacuum or atmosphere protected environment. The temperature control system of split tube furnace can set a 50-stage temperature rise and fall program, and the temperature control accuracy is +/-1℃.
The purchase value of split tube furnace:
1. One split tube furnace can cover multiple experimental scenarios and meet the needs of complex multi-step processes. Purchasing split tube furnace can reduce equipment input costs and save laboratory space.
2. The single processing capacity of 130mm pipe diameter is 2 times higher than that of 80mm pipe diameter. The use of split tube furnace can reduce the time and energy consumption costs of batch experiments, and reduce long-term operation and maintenance costs. Split tube furnace is suitable for laboratories with limited budgets.
3. Precise temperature field control and high-quality thermal field materials make the three heating zone tube furnace have excellent temperature stability, and the three heating zone tube furnace can provide a reliable guarantee for high-quality research results.

Parameters of three heating zone tube furnace:
| Product Name | OTF-1200X-III 1200℃ Three Temperature Zone Open Tube Furnace |
| Furnace Body Structure | · Three heating zone tube furnace adopts a double-layer housing structure and has an air cooling system. · The furnace of the three heating zone tube furnace uses high-purity polycrystalline alumina fiber as the material to minimize energy loss. · The inner furnace surface of the three heating zone tube furnace is coated with imported high-temperature alumina coating, which can improve the reflectance and heating efficiency of the equipment, and also extend the service life of the instrument. · Three heating zone tube furnace has a door opening and power-off function to improve the safety of experiments. |
| Basic Parameters | · Power supply: AC220V 50/60HZ · Power: 7KW · Max high temperature: 1200℃ (<1h) · Continuous working temperature: 1100℃ · Heating element: ferromolybdenum-chromium aluminum alloy · Recommended heating rate: ≤10℃/min ·Thermocouple: type K · Heating zone length: 900mm (300mm+300mm+300mm) |
| Sealing Flange | Quartz tube caliber optional: Φ50, Φ60, Φ80, Φ100, Φ13. |
| Temperature Control System | · The three heating zones of the three heating zone tube furnace are controlled by three independent temperature control systems. · Three zone high temperature tube furnace includes a YD858P type temperature controller. · PID automatic temperature control system. · Intelligent 50-segment programmable control. · Temperature control accuracy: ±1℃. · Default DB9 PC communication connection port. · Passed MET certification. · Optional computer temperature control software (for YD858P series controllers) is used to control the heating curve and export data. |

| The Size of the Three Zone High Temperature Tube Furnace | 1670mm(L)*640mm(W)*860mm(H) (size when the furnace door is opened) |
| Weight | About 100Kg |
| Warranty | One-year warranty, lifetime technical support. Special note: 1. Consumables such as heating elements, heating furnace tubes, sample crucibles, etc. are not included. 2. Damage caused by the use of corrosive and acid gases is not covered by the warranty. |
| Precautions for Use | · The air pressure in the quartz tube should not be higher than 0.02MPa (relative air pressure). · Due to the high air pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when introducing gas into the quartz tube. 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 the company's pressure reducing valve is 0.01MPa-0.1MPa, which will be more accurate and safe when used. · For sample heating experiments, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace pipe. If you need to close the valve to heat the sample, you need to pay attention to the number of pressure gauges at all times. If the number of pressure gauges is greater than 0.02MPa, the vent valve must be opened immediately to prevent accidents (such as broken furnace pipes, flanges flying out, etc.) · We do not recommend that customers use flammable, explosive and toxic gases. If the customer does need to use flammable, explosive and toxic gases for technical reasons, please take relevant protective and explosion-proof measures by yourself. The company is not responsible for related problems caused by the use of flammable, explosive and toxic gases. |
| Compliance | CE Certified, UL or CSA certification is available at extra cost. |
FAQ:
