Vacuum Muffle Furnace

Our vacuum muffle furnaces provide complete inert gas saturation, making them ideal for materials sintering, annealing and vacuum brazing without oxidation by creating multiple atmospheres for your heat treatment without limitation of sample sizes that don’t easily fit in a tube furnace.

All our vacuum furnaces are benchtop models, with temperatures from 1200°C to 1500°C and volumes from 1.5L to 31L.

SH Scientific vacuum muffle furnace is also the proven system to produce and grow graphene on metal substrate such as cooper by CVD (chemical vapor deposition) method. So called, CVD vacuum furnace.

To avoid oxidation completely, we strongly recommend the available mass flow controller and back pressure regulator. Additionally, our low-noise vacuum pump is a popular upgrade that creates a more peaceful, focused working environment.
