APPLICATIONS

A single-zone tube furnace is a type of furnace commonly used for various synthesis, heat treatment, and sintering processes. It features a single, uniform heating zone for effective temperature control. Its applications are vast, including materials science, engineering, and chemistry, where it is used in processes such as the synthesis of inorganic compounds, annealing, and ceramic firing.

standard features

• The stove’s outer casing is made of Q235 low carbon steel, featuring electrostatic and corrosion resistance on the surface. It has a sturdy metal frame shell structure, with a low furnace surface temperature.
• The chamber is insulated with alumina ceramic fiber for maximum temperature stability and uniformity, as well as low energy consumption.
• High-quality heating elements provide excellent temperature uniformity, offer fast heat-up and cool-down rates, and ensure unsurpassed temperature uniformity along the entire heated length.
• The temperature control is precise, with minimal temperature fluctuations. It includes temperature compensation and calibration functions, with an accuracy of ±1℃.
• Heating rate of single zone tube furnace tube furnace is 1-25℃/min, a suggested 15℃/min heating rate for a long service life.
• An intelligent microcomputer-based self-tuning PID temperature controller, with SCR/SSR control, can set the heating curve and program 4 groups of 30 segments for program heating, program heat preservation, and program cooling.
• The device features a circuit breaker that trips automatically during a leakage or short circuit, safeguarding both equipment and operators.
• The furnace emits an alarm signal and automatically protects when overheated or when the thermocouple breaks during the working process.
• The integrated design of the furnace cover enables easy sample placement and quick cooling.
• The ends of the furnace tube are equipped with stainless steel metal flanges, with high-temperature PTFE gaskets, which can work under vacuum, with a vacuum degree ≤5pa (vane vacuum pump).
• There are gas inlets and outlets at both ends of the flange. The pressure gauge is installed on the metal flange. The precision needle valve can adjust the amount of gas intake and exhaust, and can pass in protective gases such as nitrogen, argon, and hydrogen.
• A variety of tube diameters and heating lengths can be adjusted and customized to accommodate the different physical or chemical requirements of a process.
• Standard configurations: Furnace body -1 set, Thermocouple -1 set, Manual -1 copy, Temperature controller -1 set, High temperature gloves -1 pair, Furnace hook -1 set, Pipe plugs -1 set, Stainless Steel Vacuum Sealing Flange Kit -1 set
• Optional accessories:
  • Optional rotary vane vacuum pump (vacuum degree ≤ 5pa)
  • Optional digital vacuum gauge (1.0×10^5 – 1.0×10^-1pa)
  • Optional float flowmeter (range 60 – 600ml/min)
  • Optional corundum boat
• Quality Certificates: CE, SGS, ISO9001, TUV
• Warranty: one year，life long technical support
