Plasma ceramic retort for protecting the heating elements and to avoid charge contimination [in the LHT 02/16 LBR]
Saggar
Due to the electrically driven lift bottom, the LHT/LB series high-temperature furnaces can be charged very handily. With their all-round heating, these furnaces achieve outstanding temperature uniformity. In the LHT 02/16 LBR model, the furnace chamber is separated from the heating elements due to the use of a tubular plasma ceramic retort placed vertically in the furnace. This design prevents a certain degree of contamination of both the load and the heating elements. It is also recommended for gassing processes.
