Laboratory furnaces


PL 20/12,5	PL 5/12,5

The laboratory furnaces are intended for heating and conducting analytical works with various materials under laboratory conditions. Depending on the furnace type, heat treatment is carried out at the maximum temperature 1250 to 1600 °C.

The production of laboratory furnaces started in 1992 and since then they have gained popularity with our customers due to low prices, compactness, reliability and easy operation. For example, more than 700 furnaces of this series were sold in 2007.

The laboratory furnace has a welded casing of sheet metal and is divided into two compartments by the horizontal cross-wall. There is a working chamber with multilayer insulation and electric heaters in the upper compartment of the laboratory furnaces. The control unit is located in the lower compartment. The working chamber is lined with highly effective fibrous insulation based on silicon dioxide, additional insulation being ensured by basalt wool plates.

In the furnaces rated for T=1,250 °C, electric heaters are made of Superfechral alloy and arranged against walls of the working chamber; in the furnaces rated for T=1,400°C, heating elements are made of carborundum; and in the furnaces rated for T=1,600°C, heating elements are made of lanthanum chromite.

The temperature profile adjustment controls of the electric furnace, microprocessor-based temperature adjustment unit, switch and indicator lamp are arranged on the face panel. Temperature control and adjustment are carried out by an electronic regulator receiving the feedback from a thermocouple mounted in the working chamber.

Rapid heating (up to 40 minutes) and low energy consumption are distinctive features of the furnaces.

One of the main advantages of our laboratory furnaces as compared to peers is the possibility to replace a failed heater during 10 minutes without disturbing the integrity of the lining.
