What is sterilization of dry heat?
dry heat sterilization generally includes the location of an item to be sterilized in a furnace or thermal chamber, and heating it until it heats all the way. This process usually kills infectious organisms, even in porous materials such as ceramics. Many people use dry sterilization as an alternative to cooking for objects that cannot moisten, such as water soluble powder, oil or objects susceptible to oxidation.
those who avoid sterilization of dry heat in favor of other methods may not understand exactly how it works. This method must be used correctly to achieve a completely clean item. It also takes some time and one to two hours is usually necessary for full sterilization depending on the temperature used. An ordinary oven can be used for this process or even toasters. Item or items to be cleaned must be placed on a clean surface, not directly on the oven stand. This helps to prevent any organisWe have already been transferred to the item in the oven.
oils, powders and other non -intended objects should be placed in a clean container secured by heat before submitting dry heat sterilization. Tarva should be preheated to 320 ° Fahrenheit (160 ° C) for sterilization in two hours, or 340 ° C (170 ° C) for sterilization in one hour. Preheat should be done about 20 minutes before placing the building in the oven to ensure that the oven is hot enough to perform its work. The item should then be placed on the center stand of the oven and left for heating.
After heating the item, it should be allowed to cool inside the oven for one or two hours. This prevents the contaminated item from cooling. The user should then remove the item from the oven with a clean glove with secure heat. Medical tools and objects used in laboratory experiments are sometimes sterilworked in this way. Laboratories often contain large chambers for dry Hjezte sterilization in which sterilized holes blow overheated air into the chambers and clean the objects inside.
When sterilizing many items at the same time, it should be generally placed in an oven spread out of about 6 inches (about 12 cm) apart. This allows free air free to freely around items, which is necessary for proper sterilization. Those who do not bind dry heat sterilization do not like it in general, because it can take a very long time if many items need to be sterilized.
