WHy are wrapping paper required while sterilization?

You wrap it with paper to avoid the collection of vapour and liquid inside plates. If you dont do that they will filled with vapour (water), when you take them out. If they are still wet after taking out, chances for contamination will increase.

What is the purpose of wrapping the items before putting them in the autoclave?

Properly wrapping up items for autoclave is crucial. Since the autoclave will work as a pressure cooker, which provides pressure and steam to kill pathogens on the tools. Wrapping the items is a process you need to do repeatedly as you reuse a lot of the tools to prevent cross-contamination.

WHy do glasswares like petri dishes and test tube need to be wrapped during sterilization?

Since glasswares are sensitive to rapid changes in temperature, they are wrapped in paper and then only kept in hot air oven. Sterilization (Latin sterilis meaning barren) is the complete removal or inhibition of all live forms (living cell, spores, virus, etc.) from any object or place.

How do you sterilize glassware in a hot air oven?

When sterilizing glassware such as bottles, petri dishes and test tubes, dry heat is required and this is carried out in a hot air oven. The ideal temperature of the oven needs to reach is at least 160°C and the contents need to be regulated at this heat for 45 to 60 minutes.

What is a surgical wrap?

Why is it important to sterilize glasswares used in preparing media?

When microbiological media has been made, it still has to be sterilized because of microbial contamination from air, glassware, hands, etc. Within a few hours there will be thousands of bacteria reproducing in the media so it has to be sterilized quickly before the microbes start using the nutrients up.

What method of sterilization should be used to sterilize glassware?

The most effective and used method of sterilization of glassware is dry heat treatment using hot air oven. On exposing the glassware to dry heat, the inhibition in growth occurs due to denaturation of proteins and oxidation of biomolecules.

Why do you sterilize with aluminum foil and brown paper?

We do the former in that way (wrap with brown/kraft paper) because it’s “dry heat” sterilization and the latter (with aluminum foil) because it’s “moist heat” sterilization.

How do you sterilize glassware in an autoclave?

You’ll need a heat resistant material like aluminum foil or cotton wool plugs for sterilization of glassware in an autoclave as you can’t definitely use paper which would disintegrate with steaming under pressure. Wrapping with brown paper and aluminum foil in both cases are precautionary measures to achieve effective sterilization.
