Effective - Model ELI- HAO -Laboratory Hot Air Oven

It is mainly applicable to samples that are heat resistant. Successful sterilization can as it were to be accomplished when a suitable temperature and holding time are chosen depending on the type of microorganisms being sterilized. Louis Pasteur evolved the process of dry heat by using a Hot Air Oven. These air convection ovens have applications in many fields e.g. laboratory, medical, pharmaceutical and textile industries.

Principle of Laboratory Hot Air Oven.

Hot Air Oven works on conduction and radiation. The heat is passed inside the next and absorbed by outside items in the process of conduction. To sterilize materials in hot air ovens 170 degrees Celsius for 30 minutes, 160 degrees Celsius for 60 minutes, and 150 degrees Celsius for 150 minutes are commonly used temperatures and times.

1. External cabinet: It covers the internal chamber and is made of stainless steel.
2. Glass wool insulation: The internal and external chambers are filled with glass wool which provides insulation to the oven.
3. Inner chamber: To support long-lasting operations it is also made of stainless steel and consists of slots.
4. Tubular air Heaters: For sterilization inside the chamber for heat production tubular air heaters are present.
5. Motor-driven blower: For equal circulation of air hot air oven consists of motor motor-driven blower.
6. Temperature sensor: Inside the oven chambers the temperature is regulated and maintained.
7. Tray slots: They are made of aluminium and in the inner chamber on these trays materials are kept.
8. load indicator: How much load the oven consists of is indicated by the load indicator.
9. PID digital temperature controller cum indicator.
