This system has durable 3/8" OD "rod-hairpin" tungsten heating elements capable of use to 1,600°C and is configured with a Varian VHS-10 diffusion pump stack, and has been used for "binder-free" processes that do not contain any carbon potential for use to 10-6 Torr or better.

It has been reserved for processing optics, electronic materials, and other refractory metals (like rhenium) that must not be contaminated with any carbon.
