Steady and Regulus, do you guys backfill your syringes or draw with another needle size?
I don't backfill, I don't prefill. I just do it as I go.
1. Wipe the top of the bottle with alcohol.
2. Pull the stopped on the syringe back to the desired dose.
3. Insert needle into the bottle, push the air into the bottle, and invert.
4. Slowly pull back the stopper to a little past the desired dose. There will always be some amount of vaccuum that does not fill immediately, but once you have pulled back to the desired dose, just hold the bottle inverted for a half minute or so and the vaccuum will rise to the top. Then push forward. At this point you should have the very close to the full dose in the syringe. If a bubble or two remains, pull back a little, then wait a bit for the vaccuum to rise to the top, and push forward. Sometimes you will not get it perfect but you can always get the bubbles to small enough that they are irrelevant, if you are patient.
I honestly don't know why so many people say they have trouble with the smaller gauges. Yes, it does require a little patience because the liquid is more viscous than insulin, but really I have not found it to be difficult or overly time consuming at all. But YMMV I suppose!
