I have some 22 guage pins to draw out of amps (and then switch to smaller pins to inject with)...
Up until now, I only used amps, but just some 10ml vials... Are the 22g pins to big to draw with?
What I mean is the size of the hole the 22g pin will leave in the rubber top causing leakage... Nothing to worry about, or use a smaller pin to draw with?
