Dry heat sterilization is a widely used method for eliminating microorganisms using high temperatures without moisture. Unlike autoclaves that use steam, dry heat relies solely on heated air, making it ideal for sterilizing materials that might be damaged by moisture—such as powders, oils, and metal instruments.
The hot air oven is the primary equipment used for this process. It operates at temperatures typically ranging from 160°C to 180°C and maintains the required heat for a set duration (e.g., 2 hours at 160°C or 30 minutes at 180°C). The consistent airflow ensures even heating throughout the chamber.
This method ensures complete sterilization by oxidizing cellular components of microbes. Hot air ovens are essential in laboratories, pharmaceutical industries, and hospitals due to their reliability, low operating cost, and ability to sterilize dry glassware and instruments effectively. Contact us at +91 9210 903 903 or info@prestogroup.com for premium quality testing instruments tailored to your needs.
