A Hot Air Oven is an important laboratory instrument used for drying, sterilizing, and thermal processing of various materials. It is specially designed to provide uniform and controlled heating using dry air, making it suitable for applications where moisture must be avoided.
Overview of Hot Air Oven
In laboratory environments, maintaining cleanliness and accuracy is essential. A hot air oven helps achieve this by using high-temperature dry air to eliminate microorganisms and remove moisture from samples, glassware, and instruments. It is commonly used in educational, pharmaceutical, chemical, and research laboratories.
How Does a Hot Air Oven Work?
The hot air oven uses electric heating elements to produce heat, which is evenly distributed inside the chamber through natural or forced air circulation. A precise temperature controller ensures that the set temperature remains constant throughout the operation, allowing safe and effective sterilization or drying.
