A hot air oven sterilizes laboratory equipment and glassware using dry heat. It operates at temperatures ranging between 160°C and 180°C, depending on the requirement. The instrument is widely used for drying, curing, and heat-treating laboratory materials. Unlike autoclaves that rely on steam, hot air ovens function without moisture, making them suitable for heat-resistant items. Common applications include sterilizing glass Petri dishes, pipettes, and flasks. This ensures laboratory equipment remains free of contaminants and safe for use.
