A hot air oven is a laboratory device commonly used for drying, sterilizing, and removing moisture from materials through heated, circulating air. It is widely used in microbiology, pharmaceuticals, and chemical labs, especially where precise temperature control is essential.
The temperature of a hot air oven for drying glassware is usually maintained at 160°C for about 2 hours.
It is used to remove moisture and sterilize/dry glassware such as Petri plates, pipettes, flasks, and test tubes by dry heat.
