heat treatment furnace / soldering / gas-fired / inert gas

The VL soldering tube furnace is suitable for generating the lowest achievable operation pressures. Due to this vacuum capability, the highest purity gas atmosphere can be achieved.

The VL is a vertically mounted tube furnace with automated controls for the sample loading and unloading, in addition to, raising and lowering the furnace hearth over the integrated quartz tube containing the sample material. The quartz tube is connected to the furnace, so in loading the soldering furnace, the quartz tube and furnace hearth are raised upwards to freely access the sample area. After the sample is loaded, the quartz tube and furnace hearth are lowered and locked into position for the heat treatment process where high vacuum operation is achievable. The furnace hearth can also be raised upward and away from the quartz tube after the heating process for fast cooling of the specimen in vacuum, air, or in an inert gas atmosphere.
