The drying oven is an equipment used to dry and sterilize the glass and metal containers in the laboratory. It is also identified by the name of the drying oven. Manufacturers have basically developed two types of overalls: those that operate by natural convection and those that operate by forced convection. The ovens work, usually between room temperature and 350 ° C.
It is used to sterilize or dry glass and metal material used in examinations or tests, which is converted to the laboratory and which comes from the washing section, where it is sent after being used in a procedure. Sterilization carried out in the oven is called dry heat and is carried out at 180 ° C for 2 hours; Glassware, when heated by high temperature air, absorbs moisture and eliminates the possibility of sustaining any biological activity due to high temperatures and times used.
Quality control in ovens is a bit difficult to achieve because dry heat sterilization technique has critical temperature and time settings. In general, the spores of Bacillus Subtilis, the Niger variety, which must be incubated for several hours after the sterilization process use as biological indicators. The initial load of the biological indicator spores varies between 5 x 105 and 1 x 106. Its effectiveness depends on the diffusion of heat, the amount of heat available and the loss of heat. The action of the microbicide is conditioned by the presence of organic matter or dirt in the article. Dry heat sterilization should be limited to materials that cannot be sterilized in autoclaves.
The laboratory oven is an instrument used to dry and sterilize glass containers, which come from a laboratory wash. In other words, this chamber with a cavity, which will have a higher temperature than the ambient temperature, will remove all the moisture from the metal or glass container.
The sterilization that is effective inside this oven is called dry heat and is only carried out at a temperature of 180 degrees Celsius for 2 hours. The process of this is that the glass being heated, by high temperature air, eliminates the possibility of any biological activity being found. Stoves have different uses within a laboratory, standing out for being used with glass or metal laboratory implements.
They are also used to carry out manipulation and sterilization work on different biological elements in order to obtain a specific result. The oven or drying oven is made inside and outside with stainless steel material, for which it has great durability, and thanks to a microprocessor it has temperature uniformity. It is controlled through a digital manual.
Drying ovens have two main functions in a laboratory: Dry and sterilize the glass and metal material used in laboratory work, in examinations and tests carried out in it.
It extracts the air from the environment in which the stove is located. Therefore, it transmits heat evenly throughout the equipment, creating a natural circulation of air. They have a double chamber. The air enters through the lower part of the double chamber, is heated as it passes through the combustion chamber
This type of oven has a microprocessor controller with timing function, and its applications include drying, torrefaction, wax melting, and sterilization in mining companies, as well as in laboratories and scientific research institutes. This is a polished stainless steel chamber drying oven with the latest PID controller.
They allow products to be dried at a very low temperature, in the absence of oxygen and with the possibility of recovering the solvent. These instruments are designed for gentle drying of heat sensitive samples and usually have adjustable over-temperature protection. They are used in the areas of clinical, hospital and food analysis.
Laboratory ovens have a series of characteristics that allow them to be differentiated from the rest. So that you can choose the best one for you, it is important that you know the general characteristics that they offer:
There are countless models, so it is normal that you do not know which laboratory equipment to buy that suits your needs. At Kalstein, we evaluate them to find what you're looking for.
A natural convection laboratory stove is one that extracts air from the environment in which the stove is located. Therefore, it transmits heat evenly throughout the equipment, creating a natural circulation of air.
Among the wide variety of equipment needed to carry out the numerous activities of a laboratory, we can highlight the use of drying and heating stoves or ovens, basic equipment that is often used quite frequently.

The laboratory oven or drying oven is equipment used to dry and sterilize glass and metal containers in a laboratory. It is also known as drying oven. They work between room temperature and 350°C. In general, these equipments are made of stainless steel, both on the outside and inside, this provides them with high durability. In addition, they have a microprocessor that ensures that they maintain a uniform temperature and allows it to be adjusted digitally.
