Ovens and stoves

Laboratory ovens are necessary tools for heat treatments of all kinds.
They are used in the industrial, food, chemical, pharmaceutical sectors and in all areas where it is necessary to 'dry' samples.

Function of laboratory ovens

The function of ovens is to heat and dry samples in the laboratory.
Laboratory ovens usually reach up to 300 °C, which is why they are also used for sterilisation. In laboratories, it is often necessary to sterilise instruments or other contaminated objects.

Structure of ovens

The stoves are electrically heated cabinets. The walls are heavily insulated to maintain the temperature and they work on two general principles.
The first type of stoves are called natural circulation stoves.
They are so called because they base their principle on the natural circulation of air caused by the temperature difference between the air inside the chamber and the air outside.
A second type of stove is called a forced circulation stove because the air is moved by a fan that, thanks to the particular shape of the chamber, directs the air flow.
This second system achieves better temperature uniformity, but to achieve this result they require more complex and less economical equipment than the first.
The different stove models differ mainly in the capacity they can hold, which usually ranges from 30 to 400 litres.

The stove is also called a forced circulation stove.

Working with heat safely

The stoves are appliances that work at high temperatures and must therefore be equipped with safety systems.
They must be certified according to current safety regulations in the event of malfunction or failure of the electronic temperature control apparatus.

High temperature muffles

There are workshops that have to perform work at very high temperatures. Applications in metalworking, calcination and solid incineration work at temperatures above 1500°C.
For these laboratories it is necessary to use so-called Muffles that can reach temperatures of 1800°C.
