Bought 3ml syringes & I'm getting 120 drops per ml??!?!

[Damios]

So I've been assuming that measuring by ml vs drops is a more accurate way to measure. A ml is a ml, whereas a drop can change depending on the diameter of the tube or needle it is coming out of as well as the density of the fluid.

That being said though, I have heard that a typical amount of drops per ml is anywhere from 20-30 depending on the factors said above...but I just bought some 3ml syringes and I counted how many drops of flavor concentrate there were per ml and it was 120....which is wayyyyy more than I expected.

They are medical grade syringes from BD, so I know that they are accurate in terms of their measurement markings.

What gives??

We've had drops per ml range from 18 to 50...so that seems kinda crazy-high. Any possibility you were filling up the entire 3ml syringe, and not stopping at the 1ml mark?

What flavoring/brand is it?

 

[Damios]

Nope I am filling exactly to the 1ml line...I ain't that dumb haha.

The flavoring is all Capella's.

Maybe it's because the blunt tip needles on the end of the syringes are fairly thin and are creating very small drops? That's the only thing I can think of because apart from that I have no idea why it's so many drops per ml.

I would take the needles off, but I am pretty sure that the measurements on the syringes compensate for the amount of fluid held in the needle when you fill up the syringes. So if I were to take the needles off, 1ml would not actually be 1ml and it would end up being slightly short if that makes sense.

Lucky you! You can add less than 1% flavoring into 1ml samples with that syringe.

My favorite syringe does 50 drops/ml on most flavorings. I call it my 2-percenter (one drop of flavoring in one ml base is 2% flavoring). I'd love to find one that's 100 drops/ml - sure would make micro-batch recipes easy.

The funny thing is that I input "120 drops per ml" into my juice calculator and it came back with an error message saying "Error, drops per ml doesn't make sense, 100 is the limit"...I lol'd.

But honestly, if you want to make micro-batch recipes, buy yourself some 1ml insulin syringes. They go down to 1/100th of a ml.

Here's something even stranger. I bought 3ml pipettes from Rtsvapes. My batches were coming out very very small. So I decided to test them. I took a cup of water and a 5ml bottle. I filled the bottle with exactly 5 full pipettes. This would would make them actually 1ml pipettes , right? Not according to Rtsvapes customer service. They don't carry 1ml pipettes. They insist they are in fact 3ml. I'm not an idiot, this is very easy math 5 full pipettes filling a 5ml bottle = 1ml pipettes.

Yeah, 'almost didn't post that because we didn't mean to insinuate that yer that dumb!

So, you're using a NEEDLE to count drops...that's totally different. What I mentioned was how many drops out a flavor/vendor bottle to = 1ml. The drop size definitely changes with the gauge of the needle!

As far as we're concerned, pipettes are pretty much useless for accuracy (at least the kind from vape shops).

Yeah "RTS said" :::eyeroll::: We had an issue once and they insisted that the most accurate measurement needed was "accurate to within 5%", because that's what medical/laboratory equipment allows for 'margin of error'. Really? A 5% 'margin of error' is NOT acceptable for any medical/pharmaceutical/lab equipment. Sheesh.

5% are they insane?? Sometimes I only use 5% flavor. So it's acceptable to either have 0 or double??

This was in reference to the innacurate fills of the flavor vials we'd received - not mixing an ejuice. 'Did make us think though...if your equipment is only accurate for dispensing to 5% accuracy, that doesn't give us a lot of confidence for your nicotine bases.

Vendors usually rely on estimates only when it works in their favor. I recently purchased 500ml of Nic solution from Vaping Zone which turned out to be 10% short. When I contacted Vaping Zone, they said I am only entitled to an estimated amount - not the 500ml I paid for.... As to how they estimate the amount, they said they pour enough into a bottle past an imaginary line beyond the bottle's curve... What a sham.

Holy Moly - they measure their NIC solutions by "imaginary lines"? And then say you're not entitled to what they clearly state is a specific amount when you buy it? That (legally anyway) is a bit more than just a 'sham'.

If using a 'pour to an imaginary line' method, we'd assume that some bottles would be 'over' and some would be 'under'. But using calibrated equipment to dispense liquid into vials, the only issue would be 'improperly calibrated equipment' (by mistake or intention). 100% of our flavor vials were 'under' - it's tough to strike that up to simple human error.

:::sigh:::

OP -The viscosity of the liquid makes a difference in drop count also. Use PG when checking drops as most flavorings use PG. For the 'testers', an insulin needle (28 ga) will do 250 - 260 drops per ml of PG. Tough to suck it through the extremely small needle, but it does.

How many people really check? Perhaps VZ would like to receive an 'estimated payment'. They may not have done it intentionally ... or not. It sounds more like some ring-around-the-rosey BS response to cover their butts for lazy lab measuring practices. And that's exactly what that way of doing it is ... lazy. Their response was not a way to keep a customer, or get new ones. Certainly isn't a good business practice not to take care of it, and just tell you to go spin. You are 'entitled' to 10% of your money back or 50 mls of whatever you bought, imo. VZ credibility - toilet bound. Hopefully someone at VZ will read this thread and realize a bunch of other people did too.

For what its worth, I just recently got 250 mls of 100mg nic from WL. I got 265 mls. As a matter of fact, all the flavoring vials from WL I get are also over the 8 mls. They run a good business and they get my business.

The majority of nic vendors are NOT buying "premixed" - they're buying the stronger nic & mixing it with VG or PG 'in house' - and then selling it to us. 'Sure as hell don't want to imagine ANY vendor mixing nic by the "imaginary line method"!

On top of that, VZ's Gourmet Concentrate line contains many flavors that are known to contain Diacetyl...and they don't bother to disclose that on their website. (that line of flavors is from Baker Flavors in Russia - and they have that information on their site). Since no one can find out the source of their non-gourmet Concentrate line, then we can't trust it's diacetyl/similar free either.

We agree - WZL & TFA run a tight ship. We now get our nic from Nude Nic, but we've always had great experiences with WZL.

I have stopped ordering from VZ not only because of their poor practices, but because of their arrogant attitude. I once needed help with the Turkish flavor I had ordered from them, since after 2weeks at 8%, I still wasn't getting any flavor. They suggested a longer steep time, but when I asked how long, Leah at Vaping Zone arrogantly snapped back she would never reveal her steeping "secrets" - ever she said...
Don't know what got into me to order from them again... I probably confused either the vendor's name or else I panicked when MFS, my regular supplier switched to a new, more funky Nic. Anyway as the old cliche' goes: "Fool me once, shame on you. Fool me twice, shame on me"

5% is a very acceptable margin of error.

Say you wanted to measure 1ml of liquid in a container with 1ml markigns, 5% error would give you .95-1.05ml. If you need to be more exact than that, you should be using something that measures fractions of 1ml. If the markings are every .1ml with a 5% margin of error, that would give you .095-.105ml.

And no, syringes do not account for the volume of the needle. The liquid stays suspended in the needle when the plunger is depressed, unless you draw air through it

 

[Muero]

Yeah, 5% of 1ml is acceptable margin, but not with 500ml of nicotine. 50mls short of nicotine is big deal also given that it is the most expensive part of DIY.

5% of 500 is 25
