Drawing from almost empty vials
This is my first cycle using vials and now that I have just about finished one of the vials (there is about 2cc of liquid left), it is becoming tougher to draw from it. I continue to shoot the same amount of air into it (1cc, which is the amount I draw out) and turn the vial upside down to draw. However, since there is very little liquid left, I have to only insert the needle into vial a tiny bit so that the head of the needle can remain in contact with the liquid. Is there a different strategy for when the vial is almost empty-- such as not turning it upside down or injecting a different amount of air into it? Anyway, thanks in advance for the feedback.
