A natural convection laboratory stove is one that extracts the air from the environment in which the stove is located. So it transmits heat in a uniform way throughout the equipment creating a natural air circulation.

Convection heaters have a double chamber. The air enters through the lower part of the double chamber, heats up as it passes through the combustion chamber and is distributed evenly throughout the room.

You should keep in mind that the laboratory oven is a key equipment for drying and sterilizing glass and metal containers in a laboratory. It is also known as a drying oven and is classified into two types: By natural convection and forced convection, according to its mode of operation. They work between room temperature and 350 ยฐ C.

What is natural convection?

Convection is a way of transmitting heat by the movement of fluids and between different densities. Natural convection is one of the oldest known methods of heating equipment. It has been used for years and centuries and has been modernized to what we know today. With this type of convection stoves, what is achieved is to transform the cold flows of air into hot air that is expelled and distributed evenly throughout the interior space of the stove. In this way, an equitable redistribution of the heat that is continuously flowing through the entire equipment is achieved.

What is a natural convection oven for?

This equipment is used to dry and sterilize glass and metal containers from laboratory washing. Sterilization is another process carried out by this equipment and is carried out by dry heat at temperatures of 180 degrees Celcius for about 2 hours. Glass or metal when heated, by air at high temperatures, are completely free of any biological activity.

Characteristics of a laboratory oven

A laboratory stove is made of stainless steel, both in its exterior and interior, this provides them with high durability. In addition, they have a microprocessor that makes sure to maintain a uniform temperature and allows it to be graduated digitally.

How to use a laboratory stove

When working in a laboratory, it is necessary to wash, dry and sterilize the metal and glass containers in common use. To do this, the containers are placed inside the stove.

In it, dry heat is generated at a temperature of 180 ยฐ C for about two hours, which allows sterilization of all the material placed in the drying cavity. This eliminates any possibility of contaminating biological activity in the containers.

What is the importance of the stove?

Drying ovens have two main functions in a laboratory: Dry and sterilize glass and metal material used in laboratory work, in examinations and tests carried out in the same.

After having been used in any job, the metal and glass implements are washed and later placed in the oven for drying and sterilization, this leaves them ready for later use.

The sterilization carried out in the oven is produced by dry heat at 180ยบC for about two hours. This absorbs any trace of moisture and removes any lingering biological activity on the surface of these materials.
