Quartz tube furnace is a type of laboratory furnace that consists of a cylindrical heating chamber with a split design. It is commonly used for various heating and heat treatment processes in research, development, and small-scale production settings. Here are the key functions and commonly used models of split tube furnaces:

Function:

Heating: The primary function of a vertical tube furnace is to provide controlled and uniform heating to materials placed inside the heating chamber.

Heat Treatment: It is used for various heat treatment processes, including annealing, sintering, brazing, calcination, and thermal decomposition of materials.

Material Testing: Split tube furnaces are used in materials research and testing to study the thermal behavior, phase transformations, and physical properties of materials under different temperature conditions.

Sample Preparation: They are utilized for sample preparation, such as drying, ashing, and preheating, in analytical and research laboratories.

Powder Processing: cvd furnace are employed for powder processing applications, including powder synthesis, activation, and sintering of powdered materials.

Commonly Used Models:

STF 12/38: This model has a maximum temperature of 1200°C and a split tube length of 380 mm. It is suitable for applications requiring moderate temperature ranges and longer sample lengths.

STF 15/60: This model offers a higher maximum temperature of 1500°C and a split tube length of 600 mm. It is suitable for high-temperature processes and larger sample sizes.

STF 17/80: This model has a maximum temperature of 1700°C and a split tube length of 800 mm. It is suitable for high-temperature heat treatment applications and longer sample lengths.rotary tube furnace

STF 18/100: This model provides an even higher maximum temperature of 1800°C and a split tube length of 1000 mm. It is suitable for ultra-high-temperature processes and extended sample lengths.

It's important to note that the specifications, temperature range, and dimensions of split tube furnaces can vary among manufacturers and models. It is advisable to consult the manufacturer's specifications and select a model based on the specific application requirements, maximum temperature needed, sample size, and desired heating rate.
