Dry heat sterilization is usually carried out in dry heat sterilizers, dry bake sterilizers or high temperature hot air sterilizer equipment.
Dry heat sterilization refers to the method of sterilization with high-temperature dry hot air, the method is suitable for high-temperature-resistant glass and metal products as well as oils and fats that do not allow the penetration of hot and humid gases, such as oily ointment mechanisms, injection oils, etc., as well as high-temperature-resistant powdered chemicals sterilization is not suitable for rubber, plastics, and the majority of pharmaceuticals sterilization.
In the dry heat state, due to poor heat penetration, microorganisms are more heat-resistant, must be subjected to high temperatures for a long time to achieve the purpose of sterilization.
Usually, the dry heat sterilization temperature is 160 ℃, sterilization time is 2 hours. If you are sterilizing glass syringes and other items, the temperature is 170 ℃, the sterilization time is 1 hour. Dry heat sterilization is a technique that can kill bacteria and bacterial germs with high temperature in a dry environment, and is mainly used to sterilize items that cannot tolerate hot and humid steam.
Temperature and time for dry heat sterilization:
1, the appropriate temperature and duration for dry heat sterilization. In general, the temperature of the items for dry heat sterilization is 160 ℃, can last 2 hours. If the glass syringes and other items are sterilized, the temperature is 170 ℃, sterilization time is 1 hour.
2, dry heat sterilization sterilization principle. Dry heat sterilization is a technology that can kill bacteria and bacterial germs with high temperature in a dry environment, mainly used for items that can not tolerate hot and humid steam and can not be sterilized with autoclave.
