Types Of Laboratory Ovens, Applications And Their Parts

November 2, 2021

The laboratory furnace

It is a type of oven commonly used to dehydrate laboratory reagents or dry instruments. The oven increases its temperature gradually as time passes as well as its programming, when the temperature is optimal and stabilizes, the thermal will maintain the temperature; if it drops, it will reactivate the heating elements to obtain the set temperature. It has a control panel that shows the regulation point and the actual temperature inside the oven, it is mounted on the front for easy reading, although some previous models do not have it, these have a graduated knob which regulates the oven temperature.

Types of Furnaces and their Applications

Gravity convection ovens:

These gravity convection ovens is one of the three forms of heat transfer that carries heat between zones with different temperatures. it has an accuracy of + -2 ° C and the time in which it stabilizes is calculated between 45 minutes to 1 hour, this can vary due to the volume of material inside the equipment and the size of the chamber. Working temperature + 5 ° C ambient temperature up to 250 ° C

Applications:

They are regularly used in applications where such rigorous temperature precision is not required since their internal temperature can be exceeded by thermal inertia up to 12 ° C. Drying of materials, dehydration of substances not sensitive to overheating.

Forced convection ovens

These Forced convection ovens is one of the three forms of heat transfer that transports heat between zones with different temperatures. it has an accuracy of + -0.5 ° C and the time in which it stabilizes is calculated between 25 minutes to 40 minutes, this can vary by the volume of material inside the equipment and the size of the chamber. Working temperature + 5 ° C ambient temperature up to 250 ° C

Applications:

They are regularly used in applications where a very rigorous temperature precision is required since their internal temperature can be exceeded by thermal inertia up to 2 ° C. Drying of materials, dehydration of substances sensitive to sudden changes in temperatures or that could be damaged by overheating, highly explosive areas, industrial process control for quality.

Horizontal Flow Furnaces

These horizontal flow Forced convection ovens have an accuracy of + -0.5 ° C and the time in which it stabilizes is calculated between 25 minutes to 40 minutes, this can vary by the volume of material inside the equipment and the size of the chamber. . Working temperature + 5 ° C ambient temperature up to 250 ° C

Applications:

They are regularly used in applications where a very rigorous temperature precision is required since their internal temperature can be exceeded by thermal inertia up to 5 ° C. Drying of seeds, powders, granulated materials, drying of plants or vegetation leaves, vaporization of reagents.

Air Jet Furnaces (Sterilizer Furnace)

These forced convection ovens with direct air jet to the product have an accuracy of + -1 ° C and the time in which it stabilizes is calculated between 15 minutes to 20 minutes, this can vary by the volume of material inside the equipment and the chamber size. Working temperature + 5 ° C ambient temperature up to 220 ° C

Applications:

They are used regularly in applications where the temperature is required to stabilize quickly and the air flow is direct over the materials within the chamber. It is used for sterilization of glass materials, sterilization of stainless materials, sterilization of surgical materials, low-temperature heat treatments, quality verification of polymers and sterilization of materials that cannot be sterilized in an autoclave.

Vacuum Furnaces

These Vacuum ovens have an accuracy of + -1 ° C and the time in which it stabilizes is calculated between 20 minutes to 35 minutes, this can vary due to the volume of material inside the equipment and the size of the chamber. Working Temperature 50 ° C to 200 ° C

Applications:

Ideal for heat treatment, drying, curing, simulation of environments with other characteristics of gases or contaminated environments.

Laboratory Oven Parts

Heating Element

A heating element is an electrically charged structure that is used to create heat in electrical appliances to ensure greater control over heating. In terms of design, a heating element is usually made up of a spiral, a strip of wire made of nichrome, which works similar to the filament in a lamp that uses electricity to produce heat, and a ribbon. Once electricity begins to flow through the strip of nichrome wire, the strip works by converting electrical energy into heat, giving a red-hot glow that begins to radiate in all directions.

Air Circulation system

It allows to control the temperature with greater precision than with the gravity convection system since it homogenizes the internal chamber of the equipment more quickly. also allowing the temperature to be more uniform at all points inside the equipment.

Control Panel

It is the interface that allows us to interact with the programming that we want from the equipment, select the temperature that we are in the amount of time determined or a series of cycles that we can enter to obtain the results we need.

The most common controls are those of simple use of a single temperature that allows us to select a time of exposure to the heat of our samples, in addition there are different controls such as ramps that allow us to place different types of temperatures so that the equipment can reach etas in definite times.

Sensor

The sensor allows us to interpret the temperature in metric units of temperature either centigrade or some other, there are different types of sensors and each one is used in different equipment.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
