Rapid Heating and Cooling Cycles for Delicate Samples

The Carbolite Gero 1700°C and 1800°C bottom loading furnaces (BLF) use an electrically operated elevator hearth which rises into the furnace chamber carrying the sample.  It is an ideal choice of furnace for the handling and loading of delicate samples into a furnace chamber.

Rapid heating and cooling cycles are achieved from the electric hearth rising from its open position (down) into the furnace chamber and fully closing (up) within just four seconds.  The maximum load of the hearth is 2kg.

The design of the BLF’s hexagonal chamber offers excellent temperature uniformity and is ideal for sintering high performance ceramics, melting glass under high temperature or working with modified atmospheres.

An optional inverted crucible can be used to help retain an inert atmosphere, typically nitrogen, inside the chamber. The lip of the inverted crucible is located in a groove cut into the hearth insulation and sealed by partly filling the groove with alumina or zirconia powder.

The bottom loading furnace design can also be adapted to provide solutions to particular customers’ requirements and now comes with a hearth cage with safety interlock as standard.
