Laboratory Drying Ovens and Ovens:

Drying ovens or ovens are equipment used to dry and sterilize the instruments that are used in laboratories, whether made of glass or metal. They are of vital importance since these are the ones that guarantee the sterilization of the glassware, they are the previous step to any procedure. Ovens are used more to dehydrate reagents or dry instruments.

It achieves this, thanks to the fact that inside the temperature is higher than in the environment. According to its mode of operation, there are basically two types of stove: those that operate through natural convection and those that operate through forced convection.

Sterilization can be carried out through a laboratory oven, which is effective inside the oven and is called dry heat sterilization, which is carried out only at 180 ° C for 2 hours. During this process, the glass or metal is heated by air at a high temperature, eliminating the possibility of any type of biological activity. Because of this, to achieve sterilization of the material using dry heat, higher temperatures must be applied for a longer time.

Is laboratory oven the same as a laboratory oven?

Laboratory stoves or also called laboratory ovens are equipment that is used to dry and sterilize different materials and laboratory instruments, as well as to dehydrate reagents. There are generally two types of stoves: those that operate by natural convection and those that operate by forced convection.

These equipments work by increasing its temperature gradually according to its programming, and once the temperature is optimal and stabilizes, the thermal regulator will maintain the temperature; if this decreases, the resistances are activated again to obtain the programmed temperature again. These units have a control panel that shows the set point and the actual temperature inside the oven, it is placed in front for easy reading, although some previous models do not have it, they have a graduated knob which regulates the temperature of the equipment. .

Characteristics and maintenance of a laboratory stove

The laboratory oven is a piece of equipment used to dry and sterilize glass and metal containers. There are basically two types of stove: those that operate by natural convection and those that operate by forced convection.

The stoves are made up of two chambers: one internal and one external. The external chamber is made of steel sheet, covered with a protective film of electrostatic paint. The inner chamber is generally made of aluminum or stainless material to better transmit heat; It has a set of shelves or shelves made of stainless steel wire, so that the air circulates freely, there the elements that require to be dried or sterilized by dry heat are placed. It is isolated from the external chamber by an insulating material that maintains high temperature conditions internally and delays the transfer of heat to the exterior.

The stove has a metal door that also has its thermal insulation and is equipped with a handle also made of insulating material, which prevents the heat inside from becoming a threat to the operator's hands. The door is placed on the front part of the body of the stove, by means of a set of hinges that allow it to be opened at angles of up to 180 °.

 
 

Our best-selling laboratory oven:

Having the right lab oven is a key factor in your daily workflow. A natural convection oven works with a fan that has a heating element around it, providing heat. Natural convection is a type of heat transport where the movement of the fluid is not generated by an external source. In this process, the fluid surrounding the heat becomes less dense and rises. The refrigerant fluid then moves to replace it and this process continues until a convection current is formed. You should also know that in this process energy is transferred from the bottom of the convection cell to the top.

The way a laboratory oven works is by the principle of convection. This means that the heating element is not located in the oven chamber with the sample, it is located in a separate outer shell. In this way, the heat will not affect the sample because it will be located on the walls of the oven, which is enough to heat or dehydrate a sample. This method provides the necessary even heat distribution.

 
 

At Kalstein you can find the ideal stove or oven for your laboratory.

Because there are multiple laboratory stoves, it is important to consider the following steps when using these instruments:

All cleaning operations must always be carried out with the equipment switched off and disconnected from the network. Regular cleaning of the stainless steel inner chamber prevents the formation of residues

You should avoid introducing rusty or oxidized objects in contact with the inner chamber or the stainless steel casing. If rust spots occur on the surface

The metal surfaces of the stove can be cleaned with stainless steel cleaners such as soapy water with a soft cloth or gauze. Rinse with distilled water

The stove structures, such as: the control panel, the service modules, as well as other plastic parts must not be cleaned with cleaning products that contain aggressive products.

What are the different types of stoves?

You must bear in mind that in the market you can find several types of laboratory stoves:

Natural convection stove

It extracts the air from the environment in which the stove is located. So it transmits heat evenly throughout the equipment creating a natural air circulation. They have double cameras. The air enters through the lower part of the double chamber, heats up as it passes through the combustion chamber and is evenly distributed throughout the room.

Forced convection stove

In this type of stove, the air is forced into the machine. This air is at room temperature. They are perfect for routine daily work, providing the ideal heating and drying solution for your applications. Forced or mechanical convection allows rapid drying and heating of the sample, uniformity

Vacuum oven

They allow the products to be dried at a very low temperature, in the absence of oxygen and with the possibility of solvent recovery. These kits are designed for gentle drying of heat sensitive samples and generally have adjustable overheat protection. They are used in the areas of clinical, hospital and food analysis
