HOLY SCIENTIFIC is one of the leading science equipment manufacturer & exporter our equipments are widely used in many industries like laboratory sterilization, clean room, microbiology, pathology, bio technology, pharmaceuticals, seed & soil testing, metallurgical, food processing and many more. Our Hot air oven is widely used in various industries like pharmaceuticals, petroleum and oil industries, food processing, textiles and dyeing unit etc.


Hot air ovens are electrical devices which use dry heat to sterilize. Hot air ovens are electrical devices that use dry heat to sterilize them. Generally, the temperature range of a hot air oven is 50 to 300 ° C. It can be controlled by using a temperature controller.


Hot air oven is useful for Dry heat sterilization is accomplished through conduction. The temperature is consumed by the object’s surface, then gradually advances towards the object’s core, coating after coating. The entire thing will eventually reach the temperature required for sterilization. The majority of the damage is caused by dry heat oxidizing particles. The organism dies because the primary cell components are damaged. To eradicate the most ambitious of the resistant spores, the temperature is maintained for roughly an hour.

The inner chamber of the Hot Air Oven is made of stainless steel and outside body is made of MS, duly painted/powder coated. A gap of 75 mm. filled with good quality of insulated material in between the inner and outer chamber has been kept to prevent loss of temperature due to environmental condition. Perforated shelves, made of S.S. have been provided to get the temperature uniformity in all around the chamber and to place the sample on it. Heating element of 2000 watt (wattage may vary depending upon the size/volume of the ovens) has been fitted in all the three sides to heat the inner chamber uniformly. Blower (if opted), fitted with best quality heavy motor has been provided to circulate the inside air to make the inside environment uniform and also to provide forced dry air to the samples to get dry sooner and uniformly. Exhaust holes have also been provided at the sides of the incubator to release the pressure due to hot air.
