LH laboratory furnace up to 1340 °
A universal facility for higher temperatures and faster charge heating
The LH furnaces are flexible facilities for a wide range of uses in labs. Acquire this furnace if you need to test materials at relatively high operating temperatures. The heating elements placed within grooves in the lining ensure very fast conduction of heat towards the charge. For aggressive charges, however, the LH furnace is unsuitable. This is because the flue gases can assail its uncovered spiral or brick lining.
