1200°C – 1800°C vertical Split tube furnace-high temperature tubular furnace


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.
