Protégé Compact Split Tube Furnace with Integrated Control System (1100°C)

The Protégé XST split tube furnace has a compact, lightweight, space saving design. This model is an excellent choice to begin thermal processing in a laboratory environment. The hinged body which is split along its length allows for easy process tube changes and simple installation of process tubes with end seals attached.

The Protégé has Fibercraft™ vacuum formed ceramic fiber heating elements with free radiating wire embedded into the body of the heater and tube adapters integrated into the ends.

Excellent temperature uniformity and a programmable control system make the Protégé a valuable addition to any lab.


Due to its compact size and weight, this product will ship via Ground shipping. Please purchase this product separately or shipping charges will not calculate.
