The XST split tube furnaces have a hinged body which is split along its length. This design allows for easy process tube changes and simple installation of process tubes with end seals attached.
These furnaces use Fibercraft vacuum formed ceramic fiber heating elements with free radiating wire embedded into the body of the heater. The tube adapters are removable and interchangeable so that multiple process tube sizes can be used with one furnace. Single zone models have excellent temperature uniformity and the three zone models can extend the uniform flat zone by independently controlling the end zones.
