If you're at a point of 24 draws and desperate enough to pull a stopper, might I suggest a pen? That solves pretty much every problem you just listed, without introducing many more.Oh, I agree, I'm sure it can be done. I was struggling, however. Kept getting air, or bubbly mix. Perhaps it was because I was (an am) on a low dose, the top of my stopper was a pincushion after 24 separate draws, and letting air in? I dunno.
In frustration I popped the top, pulled out the stopper, drew out the dose, and popped the stopper back in.
Pulling the rubber stopper also led to a bit more insight on how it's shaped, which is helpful for future draws.
