Question about effect of the liquid in the tip of a syringe

[ghh3rd]

I have some 1 ml syringes that are graduated in 1/10's ml. I've used them to make several recipes, that often call for as little as .15 ml of certain flavors, which isn't much at all. My question is regarding the fluid in the tip of the syringe.

When I pull the plunger back to the desired volume, does that include the amount in the tip of the syringe, or is the flavor in the tip "extra"? At the smallest recipe measurement of .15 ml, it seems that the 'extra' amount (if it is actually extra) would significantly increase that flavor. Any ideas?

Thanks,

Granville

I would guess the measurement starts at the base of the sryinge and doesn't include what stays in the tip.

I use the ones that have the tip on the plunger that pushes all liquid out. All I've ever used, got 50 of them for under $4 on amazon.

The tip is a none issue. If you measure .15ml, when you depress the plunger only .15ml will leave the syringe. The rest will stay in the tip.

The only thing is that you need, and probably already do, to at least rinse the syringe before using it on another flavor.

Most of my flavors are in 10 ml bottles that I can't fit a syringe into, so when I've been using only one syringe for several flavors I remove the plunger, hold my finger over the tip, and drip up to the .15 ml mark for instance, then move my finger to let it flow into the 30 ml bottle, and so on. I don't have to rinse out the syringe that way. Thinking about that, I guess that the first flavor gets the 'extra' in the tip, and the rest do not... I'll have to change my method.

Some of my flavors are in glass bottles that I can fit the syringe into - I do either wash the syringe between those flavors, or use more than one syringe.

Thanks for the replies...

ps - or I can try to find some like fq06 uses

You can find them with or without for the same price. Quick search only came up with a couple and they're 100 count so $9 but you can find them on amazon or ebay for way cheaper than you'd pay on a vape site

Edit, this is cheap enough and you can stoke out a few friends

If your not using the plunger then you are correct, the extra in the tip would go into your mix. It's probably not much less accurate than the drop method though. You might want to pick up a blunt tip needle for the smaller bottles of flavors so you can use the plunger.
