Just a drop will do?

I don't really mix by drops, too inaccurate, I've used syringes with blunt dispensing needles in the past (1, 3, 10 and 30ml), they worked great but were a PITA to clean and maintain. I currently use digital scales, quick and easy.

I have several different sizes of glass droppers, for the largest (like the ones used in 30 - 60ml glass bottles), 25 drops = 1ml, for the smallest (fits WL's glass 8ml flavoring bottles), it takes 45 drops to dispense 1ml. Different sizes and types of droppers dispense different amounts per drop. The viscosity (thickness), of the fluid being dispensed also effects drop size and therefore changes the number of drops required to = 1ml. The viscosity of PG and VG changes dramatically with temperature so the drop per ml ratio is somewhat temperature dependent. Best way to determine the drops per ml ratio of a specific dropper and fluid is to count how many drops it takes to dispense 1 ml of the fluid being measured. I used a 1ml syringe barrel for this purpose.

I have read that 20drops from a syringe is equal to 1ml. am I reading this wrong? 20drops from my 1ml. Syringe, not even close! Break it down for me, please. I need to understand!

Depends on the dropper, and whether it's PG or VG -- PG is actually more like 32-37 drops; VG more like 22-27 drops. could round it, and say PG is closer to 35, VG 25.

Drops are a Funny Beast.

They are Incredible Accurate and Precise from Drop to Drop when using the Same Dropper/Same Liquid. But their Volume can Vary Substantially when Different Dropper are used. Or from Liquid to Liquid.

Nothing wrong with Using Drops to Measure a dispense liquid. Just understand that there is No ___ Drops per ml that is Entirely Accurate for All Droppers and for All Liquids.

So if you want to be able to do a Precise Measurement with drops for a given Liquid, then you need to use the Same Dropper every time.

This is EXACTLY why I stopped using drops at all, when mixing -- as soon as I started using ONLY syringes, my mixes started coming out a LOT better! Not all winners, not by a long shot, but a lot closer to the mark. 1ml syringes allow .01 measurements, and that's close enough for gubmint work. :D

First Rule of DIY is Do what Works Best for You.

I have never had Any problems using Drops. And my mixes Don't taste any Different if I use a Syringe or if I use Drops. So I use/used Drops because there was Less to Wash when I was done.
