Use of Hot Air Oven in Laboratory

A hot air oven is an electrical device that uses a thermostat to control the temperature. The unit uses dry heat sterilization as pressure built up is less. The insulation prevents heat loss. The material sterilize is usually dry as pressure is less. It is not suitable to heat the materials having liquid content.

 The materials used in the laboratories are needed to get sterilized after use. The hot air oven is used to deliver the heat treatment to the product. It has been widely used in the pharmaceutical industry, research laboratories, etc. The unit has a standard and simplified process which is cost-efficient. So the hot air oven is useful in various industries for a quick-drying process.

 Dry sterilization

Hot air oven generally uses dry heat sterilization technique for material sterilization. As the process is dry the material heated also has to be in a solid state like glassware, powder, metal equipment, oil containers. Usually, the material which has a high melting point or does not catch the fire is used for this type of sterilization.

 The working principle is simple. It operates on the conduction where the heat is conducted first at the bottom. Then it travels to the centre towards the top with or without the help of a fan. As the temperature starts raising the hot air mixture get lighter and move to the top. Then from the top, it crashes down to the bottom and creates the circular airflow. Due to the circular airflow, the temperature inside the chamber is constant everywhere. To reduce the temperature difference even more the fan and motor assembly is used to circulate the heated air mixture. The dry heat sterilization process is comparatively long time than autoclave.    

 Wet sterilization

An autoclave is equipment used for wet sterilization. It has a similar process as a hot air oven with a boiling pressure. Inside an autoclave, the water is filled that creates the water vapours and the pressure build-up which sterilizes the equipment faster. This process is generally used to kill the poison. But this process is generally more hazardous due to the high pressure.

Hot air oven advantages

Hot air oven is a laboratory and scientific equipment which uses dry heat (hot air mixture) for sterilization of laboratory equipment.

Water is not needed for sterilization like an autoclave.

The pressure build is less which is safer while operating.

More effective to work and smaller in size.

Operation is simple

Price is low

Hot air oven - guide

Hot air ovens are laboratory and scientific equipment which uses dry heat (hot air mixture) for sterilization of laboratory equipment.

The dry heat sterilization process is developed by Louis Pasteur to sterilize the equipment using the hot air ovens. Dry heat sterilization is the heating process in which the material which is placed inside the oven has the characteristics which will not melt, catch fire or changes its form while heating at high temperature.

Our hot air oven runs at extremely high temperature for several hours to destroy the bacteria. The general temperature range required for operation varies from 5°C to 450°C as per the customer need.

Most of the pharmaceutical industries use these hot air ovens to sterilize laboratory instruments and materials because they are simple to operate. The lab ovens also offered a quick dying process.

Natural convection oven

Inside the natural convection oven the fan and the motor is not available. The air circulated naturally by the means of gravity. Hence it is also called a gravity convection oven. As the hot air oven starts operating the air gets heated up and the air flows up. The temperature is not wholly uniform in this oven.

Hot Air Oven Types

The hot air oven uses dry heat to sterilize the equipment. This equipment will not melt or catch fire while heating. The process destroys the microorganisms and bacteria while heating. The temperature range of hot air oven is between 50°C to 450°C with different types. The types are listed below

 1) Natural convection oven – Inside the natural convection oven the fan and the motor is not available. The air circulated naturally by the means of gravity. Hence it is also called a gravity convection oven. As the hot air oven starts operating the air gets heated up and the air flows up. The temperature is not wholly uniform in this oven.

 2) Force convection oven – These types of laboratory oven has a fan and a motor assembly. So that the heated air is circulated from top to the bottom. This method provides a uniform temperature throughout the chamber and also provides the fast heat up time.

 3) Side Draughts oven – This oven has the fan and the motor assembly but from the side. The hot air flows from the left to right direction or vice versa depending upon the fan placement. These hot air ovens also provide a uniform temperature distribution all over the chamber.

Types of hot air oven

Natural convection oven – In natural convection oven the temperature is achieved naturally (gravity convection) without the use of a motorized blower. The temperature distribution is not uniform in this type of oven.

Forced convection oven – In a forced convection oven the motorized blower is used to achieve the desire working temperature. The blower is fitted to the motor. The temperature achieved is fast and uniform in this type of oven as compared to the natural type.

Side draught ovens – These type of ovens produces airflow from one side to the other. This type of lab oven produces fast heat-up speed and less recovery time with minimal maintenance.
