A hot air oven is a laboratory device used for drying, sterilization, or thermal testing of various materials. It functions by circulating hot air, often through forced convection, to ensure uniform temperature distribution and effective treatment of products. Hot air oven is extensively employed for the sterilization of glassware, metal instruments, and heat-stable powders and oils, ensuring contamination-free outputs in the laboratory. Operating typically within the temperature range of 160°C to 180°C for controlled durations, the hot air oven complies with established standards such as BIS, ISO, and WHO guidelines, guaranteeing consistent performance.
Hot air ovens provide controlled dry heat for sterilization, drying, and thermal testing in laboratory and industrial settings. Their precise temperature control and even heat distribution allow reliable performance for prolonged operations, supporting both routine and high-throughput workflows. In addition to sterilization, hot air ovens are extensively used for thermal testing and quality assurance. Materials such as plastics, rubber, pharmaceutical powders, and lab reagents can be exposed to defined temperatures to assess thermal stability and heat resistance. Our hot air ovens are designed to meet safety and performance standards, including BIS 3743: 1979, ISO 17665 for sterilization, and WHO Laboratory Biosafety Guidelines. They feature insulated chambers, precise temperature controllers, and uniform airflow systems to ensure reproducible results.

It is essential to measure the life cycle of a polymer product when exposed to the atmosphere due to versatile environmental conditions. This is why, testing the durability and longevity of polymers exposed to the environment is necessary for assuring customer satisfaction and proficient manufacturing of the product.
-
The Salt Spray Chamber is a widely used testing machine used for determining the corrosion resistance of the tested sample in a salt-laden environment. However, it is very important to understand and evaluate the effects of a corrosive environment on the sample, and to create such a corrosive environment around the sample, salt spray chambers are the finest lab testing instruments.
-
The cyclic salt spray chambers are highly advanced to simulate and replicate extreme weather conditions such as humidity, condensation, air wetting & air drying. This enables the manufacturers to conduct neutral salt spray tests with no hassle and measure the rust proofing of the specimen.
