Lab Tube Furnaces
Tube furnaces are typically used for processing small samples or heating in an inert atmosphere. The single and three-zoned construction is designed to create precise temperature control. Three-zone control enables the user to select a different temperature in each zone (e.g. for gas applications or material experiments). Some models offer split-hinge design, which easily allows you to change the tube.
