L muffle furnace up to 1200 °C

A universal laboratory aid that can handle even demanding operations

You will appreciate the well-roundedness of this facility in laboratories of all types. Thanks to its heating spirals placed within ceramic plates, this furnace is partially protected against mechanical and chemical damage. The L furnaces have a venting bleeder for drawing off flue gases. However, they are not suitable for pyrolysis. Their high-quality construction and materials used, meanwhile, ensure that the L furnaces can handle even demanding operation.
