Especially designed for ashing in the laboratory
The LZ furnace ideal for the oxidation of samples and for testing to determine ash quantity. It is also suitable for any applications in which ample fresh air and also exhaust from the furnace atmosphere are required.
Air is circulated throughout the internal furnace chamber and exchanged from six to twelve times per minute, depending upon the furnace temperature. The oxidation process is supported by the strong flow of oxygen. Air is preheated before it enters the LZ furnace chamber, thus allowing uniform distribution of heat even at high-temperature operation. The furnace is equipped with an exhaust chimney
