Sterile means free of living organisms, so a sterile field is an area that is completely clean of any living organisms. This is the kind of field that surgery is done in to prevent infection. A non-sterile field is an area that though clean, may have living organisms such as bacteria on it.

Sterility
Non-sterile differ from sterile products, in that they are allowed to contain some microorganisms and the content such microbes are specified in pharmacopoeial.
As soon as you open a dry sterile container it is not sterile any more due to stuff falling on it. Studies do show that the longer a sterile field is exposed the higher rate of contamination. There is less contamination with a covered field. Jim RN
Yes you can buy non sterile gloves at home depot, or any medical supply.
altho it dosent have to be sterile it could infect the wound if it is not. but a non sterile cover is better then none at all.
