A hot air oven is an essential laboratory and industrial device used for dry heat sterilization, baking, and thermal testing. Widely utilized in medical, pharmaceutical, food, and research sectors, it provides uniform, controlled heating to sterilize equipment, cure materials, or conduct heat resistance tests.
In Bangladesh, where hygiene, safety, and quality control are increasingly prioritized, regular and professional hot air oven service is vital to maintain optimal performance, compliance, and equipment longevity.
A hot air oven operates by circulating heated air inside an insulated chamber to achieve sterilization or drying at temperatures typically ranging from 50°C to 300°C. Unlike steam sterilizers, hot air ovens use dry heat, making them suitable for materials that may be damaged by moisture.
Common applications include:
Sterilization of glassware, instruments, and powders
Drying of samples and reagents
Heat treatment of materials for research and quality assurance
Aging tests and thermal resistance studies
Proper servicing ensures:
Accurate and uniform temperature control for effective sterilization or testing
Prevention of overheating or underheating that could compromise sample integrity
Safety by checking electrical systems and safety interlocks
Reduced downtime through proactive maintenance
Compliance with industry and health regulations (ISO, WHO, GMP)
