A split tube funace is a tube furnace that can be opened to allow for the easy installation and removal of work tubes and reaction vessels. Carbolite Gero's TS split tube furnace range is constructed in two halves, joined together with hinges, and fitted with pneumatic dampening struts for ease of opening.

The main benefit of a split tube furnace is the ability to open the furnace to allow the easy installation and removal of work tubes and reaction vessels with ends and fittings that would otherwise be impossible to fit into a non-split tube furnace.

There are numerous applications where it is beneficial to use a split tube furnace as the process of installing and removing is made much easier and faster than with a non-split furnace. Rotating, oscillating and gradient tube furnaces all incorporate a split design. Split tube furnaces are frequently used in applications such as the tensile testing of materials, pyrolysis, chemical vapour deposition, graphitisation etc.

With the correct accessories, split tube furnaces can be used both horizontally and vertically.
