drops to mls??

[Village_DIYer]

I ordered a bunch of 3ml testers, the one thing really confusing me is drops to mls. How can i measure drops to mls when i have such small bottles? I use ejuicemeup and the standard is 20 drops per 1ml. Should I just go by that considering I have only 3ml bottles or do you have any other methods? How many drops per ml are in those 3ml plastic testers??

depends on a drop. a 'drop' really isnt a specific quantity, it depends on what you are dropping with. only way to test it yourself is to see how many drops of whatever your using to drop into it, fits in that 3ml tester.

I use 20 to 25 drops per ml. I use mostly 80%+ VG...thicker drops means less drops per ml. Some less than 20. After awhile you will get a feel for it. Many of my exact mixes suck. Many of my less exact mixes are terrific. The diy forum has beaucoup info.

some of mine are 24 dr per ml and some are 40... get a 1ml syringe fill by drops from the plunger side to either 1ml and you get your number or to .5ml and multiply by 2

As said, there is no magic number. Mark a bottle off in 3rds (1 ml) and count how many drops of whatever you are using to reach your mark. The little hair rubberbands @ the Dollar Store are handy for that. Don't overthink it. I eyeball most mixes.

Thinner liquids (PG, flavoring) will create slightly smaller drops than something thick, like VG. So drops are not accurate. vapero was right. pull out the stopper from a 1ml dropper and count them out. I get free ones from the local drug store. Just go back to the pharmacy and tell them you have a relative coming to visit and need a couple of 1ml and 5ml syringes for their child's medicine. Some pharmacies use dropper-like devices (Walgreens), others use graduated syringes for the 1ml size.

Also depends on the viscosity of specific liquids and wetting properties of the cap on the bottle.

Same bottles... One has a smooth surface on the dropper, the other has a more rough opening... The rough opening will produce larger drops. And vg is definitely going to produce larger drops than flavoring in the exact same bottle.

Yup, juice viscosity and the dropper will affect how many drops are going to make 1 ML. The only time I use drops is if I add something at say 1 or 2 drops per 10 ML of juice. I typically don't make juice in quantities bigger than 50 ml at a time and measuring 0.20 ml of an ingredient is difficult.

I would look for what is used to make a standard "drop" and use it always for consistency. I used a 16 gauge Luer Lock needle when I DIYing for that short time. I used it again when I was adding WTA to juices.

Rather than just using various bottle and eye droppers, I figured I was consistent.

I have 1ml syringes marked with all the intervels. Makes percentage mixing really easy. I never mix by drops unless I add a few drops here or there for a little extra love[emoji7]

A 1ml syringe will measure 0.1ml quite accurately

They are calibrated without the needle attached. It's just not worth it to me to use a syringe for these small quantities. Works for me, but as always, YMMV

The amount in a 22 ga needle is insignificant according to my own tests. I'm not arguing which method is better, just pointing out that 0.1ml can be fairly accurately measured in a 1 ml syringe. If one were concerned about that margin of error then the syringe can be short filled slightly by an easily tested amount since it is graduated in 1/100th ml.

I measure drops per ml with a graduated cylinder. The drops will also vary due to the flavoring viscosity.

And if you use a glass eyedropper then each individual dropper must be calibrated and marked because there is significant variation in the dropper ends. If you use a syringe and needle then a little stick-slip can put out multiple drops when one was intended, making it an art form.

Every method has some margin of error, including weighing. Every method. I personally picked a method that was "good enough" in terms of accuracy and is expeditious for me. I get consistent results as best I can taste.

And I liken it to cooking, for example adding spice and seasoning to food or fruit topping on a pastry. How many chefs measure the fruit topping portion for each pastry to 3 significant figures and worry if some jelly remains on the spatula?
