The lift bottom furnace raises samples to furnace with the elevator mechanism. The homogeneous temperature distribution is provided by heating elements on each walls placed in the furnace. The lift bottom furnace is provided more homogeneous heating compare to the chamber furnaces.
The biggest advantage of the lift bottom furnace can easily placement of the samples to the up-down moving bottom and the operator can easily refractory change without any technical service for damaged refractory bottom such as glass shedding or product melting. It is provided less exposure of the user to high temperature compared to the lid models.
For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10 °C/min should not exceeded. Flammable and explosive products must not be used in the furnace.
