ive noticed the same thing, ive gotten gear from 3 different labs, and all of them seem to come out to 9 mL. ive read about this same issue on another forum, and seems to be a going fad. some people mention to volume between the tip of the syringe to the bottom of needle, basically the little area in the neck of needle. also heard people talk about measuring to the short side of the 1 ml line instead of the far side of the mark, if you know what i mean
