Muffle Furnace

After years of R&D alongside leading commercial and university labs, SH Scientific has manufactured one of the most durable, intuitive muffle furnaces in the world.

Our furnaces rapidly heat to 1050°C, 1200°C, 1500°C, or 1800°C, depending on the series. Temperature-specific heating elements and housing ensure thermal efficiency and remarkably low surface temperatures.

From economical general-purpose models to ultra-high-temperature furnaces, all equipment is subject to the same rigorous inspection and quality control processes.

Use with our low-noise vacuum pump for reliable inert gas saturation without the exhausting background commotion.
