How much liquid would be in a 14 gauge and 18 gauge blunt tip needle? The new flavors i got are in bottles too small for my smallest syringe. I'm doing only in 10ml bottles for my mixing of my new flavors so % need to be pretty exact. I'm just curious if anyone would know how much liquid I can assume would be in the needle.
Yes I'm a noob and this may sound like a stupid question to some but please just help me out. And yes I know the other answers are to measure by weight. I plan on doing this soon, but I want to know its possible to make vapeable liquid before investing too much more.
A two inch long 18 Gage needle will hold .03 milliliters.
Here is a wiki page with the internal diameters of common needles

Calculate the volume of the needles internal space.
This has been talked about a few times, try searching more if these don't help.

Mainly, just don't forcibly push the air out to empty your syringe. Measure your amount, push it out smoothly, then force the rest back into your flavor bottle or your wash cup.
Thanks I tried a couple different searches that didn't turn up much. I think that's the best option to go with until I switch to weight.
No problem. Also as long as it's not a super potent flavor, or you're not mixing a small <15mL batch, being off by a drop or two isn't going to make a huge difference either.
I definitely like mixing by weight since I've switched. Much faster and cleaner (for me at least).
its what in there pre measurement and stays in post exodus. it doesnt matter. put the leftover in the blunt tip back in your flavoring bottle. fwiw, mixing by syringe and by weight dripping from the flavor bottles [that have drip tops] mixing by syringe is far more accurate. i mix by weight because im lazy...
Yeah, the needle shouldn't affect the measurement. I wondered that too when I first started, but then learned about "dead space" in syringes. (I've never been in the medical field so I didn't know much about syringes). You can google "Dead space syringe" and come up with explanations with how it works. Basically, the dead space shouldn't contribute much at all to the total volume.
The way i look at it is, it's all about consistency. as long as you are measuring everything the same (looking at the meniscus every time), then there's no reason to find out how much liquid there is in the needle. If there's .03mL in there, there will be an extra .03mL of every ingredient. So what if you end up with 10.1mL instead of 10.0mL total juice in the end.
