K EEP IT STERILE 1. The Needle must never touch anything which isn't sterile. 2. The barrel tip of the syringe should also not touch anything except the needle's hub end. (this could contaminate the entire interior of the barrel) 3. The rubber plunger should not be touched. 4. The area of the plunger that extends into the barrel should also be avoided. So, that leaves just the outer barrel, the finger flange, and the thumb tip of the plunger.
