thanks guys but you misunderstood. i have taken the rubber stopper off, i wounltnt do that. what i have done is poke a needle through twice to draw out the gear but i wont be using anymore from the 10ml vial (only used 2ml) i want to save it for next time maybe 3 or 4 months. wanted to check...

sorry for the question but i dont know much about vials.
