Hot Air Oven Construction

A hot air oven is equipment used for dry heat sterilization. In this method, the equipment is heated inside the oven at a specific temperature to kill the microorganisms. The materials used in laboratories is a good conductor of heat so they serve to be ideal for dry heat sterilization.

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. Further more details are provided so read more to get a complete understanding.

Construction of hot air oven

Cabinet – The cabinet is the outermost body of the hot air oven. It consists of stainless steel. It is insulated from the inside so that the heat won’t escape and the temperature inside the chamber remains constant.

Shelves – The inner chamber is provided with shelves. The material need to be sterilized is placed on the shelves.

Door – The hot air oven has a door on one side fitted on the heavy hinges with insulation provided. The gasket is provided on the side which minimizes the heat loss during the operation.

Thermostat – The main role of the thermostat is to maintain the desire heating temperature inside the chamber. It is connected with the sensor which senses the temperature and maintains as per the settings.

Control panel – The control panel is placed on the front side above the door. It has various display panels and switches for measurements.

Fan – The fan is provided on the top which is driven by the motor. It circulates the hot air oven inside the chamber to ensure uniform temperature heat distribution.

Air heaters – The heaters are placed on both sides of the chamber. The required heat for sterilization is generated through heaters.

Custom laboratory oven

Some applications demand different kind of lab oven rather than the standard ones; therefore we also manufacture customized hot air oven as per the customer need. The customer defines the specific size, temperature range and other accessories. Our team can make sure to deliver your requirement with the quality standard at a competitive price.
