# Vacuum Laboratory Furnaces

Many applications require vacuum heat treatment, for example vacuum soldering and brazing, vacuum annealing, sintering etc. In general, a laboratory vacuum furnace is suitable for heat treatment in a defined, mostly non-oxidising, atmosphere. Additionally, vacuum furnaces are suitable for atmospheres with defined oxygen concentration different from the air composition (e.g., 100% pure O2). For laboratory vacuum furnaces, the range of available gases is even higher, making them suitable for research and development applications.

## Laboratory furnace, metal insulation (LHTM/W)

The cylindrical usable space of the laboratory furnace is surrounded by the heating elements and insulation material. The heated chamber is integrated into the water cooled vessel. As a result of the small volume, the LHT is ideal for small samples and requires minimal operating space.
