Ok I'm drawing from ampules using a 18G needles, now when i fully draw all the test from it, i get quite of bit of air in the syringe so i push up the plunger little by little to allow the air out, but the liquid keeps coming out the needle instead of the air, i dont want to continue to do this, since it seems like im loosing quite of bit (still get the 1cc btw) never hard this happen the first 5 weeks, i dont like the idea of injecting with 1/4 of air in the syringe, thanks
