Dry sterilizers are now in most countries considered junk, most health inspection agencies are requiring facilities upgrade to steam autoclaves.Stream autoclaves use the high temperature and steam pressure to kill spores and bacterial growth on all reusable equipment. To ensure the sterilizer is functioning correctly spore tests are required and in some cases must be done every month, the record of these tests must be posted and kept on file for health department inspection. Dry heat sterilizers tend to damage equipment and in most cases fail to completely kill bacterial and spore growth on the instruments .
Steam sterilization uses much less energy and time than dry heat methods. In order to kill spores a dry heat sterilizer needs to reach and maintain 170°C for one hour. An autoclave only needs to reach 121°C for 15 minutes.
The autoclave is a device used to sterilize equipment and supplies using high pressure and high temperature steam. It is commonly used in medical and research settings to eliminate bacteria, viruses, and fungi from tools and materials to prevent contamination and ensure safe use.
Autoclave is just like your cooker. It is usually bigger in size and more sturdy. The temperature goes up to about 120 degree Celsius in the cooker. It can go up to 140 degree Celsius in case of the autoclave. There is high pressure and there is water vapor. You allow one whistle to to go ahead. it will expel most of the air out of the autoclave. You allow the steam to work on the content for about half an hour. It will kill all the pathogenic bacteria for sure. (Pathogenic bacteria are better killed by moist heat as compared to dry heat.) Then you remove the whistle and allow the water vapor to escape. If you remove the lid at this stage, the cloths inside will emit the steam. But they are dry. You can wear them.
Pasteurization
no.it is an example of moist heat sterilisation
Keep it dry to avoid oxygenation bond that result rust
Standard operating procedure for hot air oven operation
wht is the difference between lund and choot?
whats good in wet market??????
They have mountains in them, they are both rainy, they are both hot and sometimes dry..
Wet vacuums hold more weight than dry vacuums. Another difference is speed. Dry vacuums are quicker because they have a wider hose so they pick more things up at the same time.
There are big differences between the two types of tropical climates that exist. This main difference is that one is hot and dry while the other is hot and wet.
