Description

SH Scientific’s benchtop vacuum muffle furnace ensures an oxygen-free environment for thermal treatment. It also facilitates a carbon-free atmosphere for applications like battery anode material development, metal injection molding, metallization, and sintering.

Unlike narrower tube furnaces, the muffle chamber design accommodates bulky samples for more efficient, cost-effective processing.

Key Advantages

Total environmental control: An optional digital mass flow controller and back pressure regulator ensure zero oxidation for material purity.
Innovative design: Vacuum pump overcomes the non-crossing streamlines phenomenon for full inert gas saturation—even in the corners of the chamber.
Versatile atmospheric control: Custom and pre-programmed settings allow multiple inert gas environments within a single treatment cycle (e.g., burning in air, purging air and pulling a vacuum, introducing inert gas, and then sintering).

Product Series

Each of these convenient benchtop models is built and rigorously tested in South Korea, then delivered and supported from the US.

Low-noise vacuum pumps are also available for a quieter, more pleasant, and more focused working environment.
