What's a sterilized needle?

Answer 1

basically it just's a needle that's been cleaned to kill any bacteria    

or germs on it, so there is no risk of infection when it is used.

Answer 2

heat up a syringe....use a lighter or match for best results.

Answer 3

a needle that comes wrapped from the factory.

Answer 4

A needle is a beveled hypodermic needle with a luminal bore and used to pierce the skin for the delivery of medicinally useful substances.

The needle must be sterilized to prevent the introduction of viable bacteria or viruses that may be present on the needle during its manufacture or storage.  Sterilization can be by many methods, including toxic gas (ethylene oxide usually) or by autoclaving (high steam pressure).
