vials

[mish12345]

just about to inject a friend but neither of us have used vials before, we need to draw from two vials into the same barrel but are confused as to how to do it. the book I have explains how to draw from one vial. I dont see how you can create a vacuum in the second vial once you have drawn up solution from the first one already.

any answers asap much appreciated !

How old are you guys? Its easy draw whatever amount you are going to in air, i.e 1ml of air, and inject air into vial now draw 1ml of oil....draw another 1ml of air and inject into second bottle and draw 1ml
