I just have to wonder, since I noticed that a 306 atty fits perfectly in the neck of your 5, 10, & 30 mL bottles, did you select these bottles on purpose for that? Or is it just a happy coincidence?
And by the way, in case anyone hasn't noticed, a 306 atty fits perfectly in the neck of most* FSUSA bottles.
Makes it way too easy to dip it instead of dripping!
* Not the 3 mL sample bottles, and I don't have anything larger than 30 mL yet.
