A Hot Air Oven (Lab Type) is a precision-engineered laboratory heating device designed to provide dry heat sterilization and thermal processing of materials in a controlled environment. It operates on the principle of convection heating, using high-temperature air circulated within a closed chamber to uniformly heat and sterilize laboratory tools, instruments, and samples.

The lab-type hot air oven is widely used in microbiological labs, research centers, pharmaceutical industries, food testing labs, chemical labs, and educational institutions. It is essential for applications that require sterilization of items that are moisture-sensitive or cannot be autoclaved (e.g., glassware, powders, metal instruments, and oils).

The heating system uses nichrome wire elements placed within the walls to ensure uniform heating. A temperature controller—usually digital PID or analog thermostat—allows users to set and maintain specific temperatures, usually ranging from ambient +5°C to 250°C or more.

Air circulation (natural or forced by a fan) enhances uniform temperature distribution throughout the chamber, ensuring consistency and repeatability in testing or sterilization processes. Safety features like over-temperature protection, auto-cut-off, and alarm systems further enhance reliability and operator safety.
