Our Hydrogen Bell Jar Furnace features a space-saving design and includes an electric actuator raising the chamber for easy and complete access to the loading area. Pneumatic locking clamps ensure a vacuum-tight seal isolating the chamber environment.

A retort with an independent gas line keeps binders and volatile products from entering the hot zone, while at the same time improving temperature uniformity. The gas exit has a burn-off assembly for removal of hydrogen or other flammable gases.
