The Mellen TV-Series Clamshell Tube Furnace, model TV13.25‑1.25×12‑81, provides a truly round 1.25″ diameter heated bore with 12″ of internal length, safely reaching up to 1,325 °C in air and up to 1,600 °C in vacuum or inert gases. Unique to this series, its clamshell design and fully supported Vulcan heating elements mean there’s zero sag across the bore—even at high temperatures—making it ideal for long-length processes or premium precision applications .
Mellen’s engineering supports custom diameters up to 36″, with heating tailored by wire composition (Chromel, FeCrAl, APM, Pt, Mo) to match target temperatures and atmosphere compatibility. Units ship without controller, but are compatible with Mellen PS205/PS305 PID systems. Whether used for materials research, ceramic sintering, or electronic annealing, this furnace is built for repeatability under demanding conditions.
