LMH

What are LMH muffle furnaces?

LMH laboratory furnaces are designed for processes involving aggressive vapours, emissions or loads that could damage exposed heating elements. The heating spiral is wound around a durable ceramic muffle, helping protect the heating system from direct exposure to aggressive process conditions.

This construction improves operational reliability, reduces contamination risk and supports stable laboratory heat treatment processes under demanding conditions.

Typical applications

• Testing of aggressive loads and vapours
• Laboratory heat treatment under controlled conditions
• Material testing and development
• Processes with aggressive emissions
• Repeatable laboratory thermal processing

Why embedded heating elements matter

The ceramic muffle separates the charge from the heating system, helping protect heating elements against aggressive vapours and contamination during firing. This solution contributes to longer furnace lifetime and more reliable operation in demanding laboratory environments.

Related laboratory furnace series

For standard laboratory heat treatment applications without aggressive vapours, consider the universal L series or the more economical LE series .

If you require vertical loading configuration for similar protected laboratory processes, explore the LMV series.

FAQ

What is the advantage of a ceramic muffle?
The ceramic muffle helps protect heating elements from direct exposure to aggressive vapours, emissions and contamination generated during thermal processing.

Are LMH furnaces suitable for aggressive vapours?
Yes, LMH furnaces are specifically designed for laboratory processes involving aggressive vapours and demanding operating conditions.

What is the difference between LMH and standard laboratory furnaces?
Compared to standard laboratory furnaces, LMH models use embedded heating elements around a ceramic muffle to improve protection of the heating system during aggressive processes.
