Syringe loading question

[-Ender-]

The syringes I've been using since the beginning have always had this protruding dimple to seat itself when fully depressed.

Because that takes up some volume, I've always loaded .1ml more to get the actual dosage I need.

I've never truly checked if that plunger actually equals .1ml, can anybody confirm this?

See image for reference.

.1ml might not matter to most. But I pin everyday, so that much can make a huge difference.

I know exactly what you mean. No picture necessary.

During an injection with a traditional syringe there is what is known as "hub loss". Hub loss is the oil/medication that is left in the hub of the syringe after injection.
To avoid this loss for intermuscular injections some people leave a very small bubble of air in the syringe to be sucked into the barrel during aspiration this air allows all of the oil/medication to be expelled from the syringe. The other option is to load slightly more oil/medication to account for the lost bit at the end of the injection.

You are overthinking things incorrectly:
The syringes that you are talking about are designed to solve the problem of hub loss. So there is no reason for you to add the extra .1ml Just load it with your needed volume. Period.

I do leave a bit of air, then bring the bubble to the top before injecting. I do this so that last bit of air pushes every bit of oil out of the "hub".

I was going to measure by a very basic test I thought of.

Basically prepping my syringe as I always do. Then back filling into an insulin syringe. These are far easier to read and the base is perfectly flat.

Exactly. Putting air in the syringe is a completely different classification of injection. If you are worried about the oil in the needle then pull the needle off, pull air into the syringe, put needle back on, and push oil back into the substance container.
