What's the vertical split tube furnace ?
A
vertical split tube furnace is a type of furnace that has a vertically oriented heating chamber, which is split into two halves. This design allows for easy loading and unloading of samples or materials into the furnace.
The split tube furnace typically consists of a cylindrical heating chamber, which is made of a refractory material such as alumina or quartz. The heating element is wound around the outside of the chamber to provide uniform heating.
The split tube design allows for convenient access to the heating chamber. One half of the chamber can be opened, either manually or with a motorized mechanism, to allow for easy insertion and removal of samples or materials. This is especially useful for processes that require frequent loading and unloading or for experiments that involve multiple samples.
The split tube furnace is often used in research laboratories and industrial applications for various heat treatment processes such as annealing, sintering, and brazing. It is also popular in materials science and metallurgy for studying the properties of different materials at high temperatures.

High-temperature multi-zone tube furnaces are advanced laboratory equipment used for various applications requiring controlled temperature environments. These furnaces typically use high-purity quartz or alumina tubes and feature multiple heating zones (ranging from 2 to 5, or even up to 8 zones) that can be controlled separately. This design allows for precise temperature profiles and excellent uniformity across different sections of the furnace. They are capable of reaching maximum temperatures up to 1300℃, with some specialized models designed for higher temperatures. The multi-zone control is particularly useful for thermo-treatments under vacuum conditions and gas protection, providing versatility for research and industrial applications in materials science, chemistry, and engineering. Customization options, such as varying the heating zone length and the number of zones, are also available to meet specific requirements .
Applications and Uses
High-temperature multi-zone tube furnaces find extensive applications in the fields of materials science, chemistry, physics, and engineering. Their ability to create controlled atmospheres and precise temperature gradients makes them ideal for a variety of processes. Notable applications include thermo-treatments under vacuum or gas protection, synthesis of advanced materials, and the study of phase transitions. The versatility of these furnaces allows researchers and engineers to push the boundaries of what is possible in material synthesis and modification, contributing significantly to advancements in technology and science .
