Can i use an 18 gague to draw from a 2 ml vial? I know if it is 10-50 cc's it's not a good idea...but will it be ok if im only drawing from it twice? I ordered 100 18 gague pins to draw...so that is why i ask the question. I figured since i will only be drawing twice with the 18 gague..the rubber stopper will hold up alright..thoughts?
