A observation and a Thank You

[Britches]

First of all thaks to all that replied to my last question!!! If you recall I was asking about the 20 drops per ml, Well this is what I came up with- I just recieved a graduated cylinder and a couple needles to measure my homemade brew and found out that the droppers, pipettes, and dropper bottles are about 55% the stated 20 drops per ml., which is fine. I just don't like making 2.5ml bottles after countin all those drops. Since my DIY is 18mg at 75% PG and 25% VG I made marks on a graduated cylinder for each. Meaning Fill with Nic juice to the first line- add PG to the next line-add VG to the last line then transfer to the bottle add the required flavor (according to the calculator) shake like hell and I can have a 20 ml bottle in a minute. Bear in mind that I had to almost double my flavor percentages as the origional reciepe per drops was off by almost 45% Again thank you for all the replys and the warm welcome and hope trhat one day I may be able to help someone else

I like your method. I'll have to give that a try.

Yeah it really depends on the thickness of the liquid and the particular dropper tip. I don't need to measure exactly unless I am making a DIY liquid. For filling a 1ml cartomizer, counting drops, waiting, then adding as many more as it will take, works fine for me. Then thorough cleanup and 15-20 min of settling on all sides.

I don't know about the drops... their volume would seem to depend on the dropper itself and on density and surface tension. I'm assuming it's some very complicated math, but I don't remember and certainly don't feel like looking it up. I believe it's accepted that for water "a drop" equals 50 microliters, and that's why 20 drops - 1 ml. But I'm very unsure about the various liquids we're using.

In any event, I seem to be using syringes for anything these days. So really don't care about how big the drops are, and I'll never count drops - it's crazy! I use syringes to fill cartos, and even carto tanks, to play with flavors and PG/VG (not feeling ready to add the nic into my mixes just yet, but my 0 nic grapefruit is to die for!). Right now I'm dripping some blueberry using a 1 ml syringe (no needle) as I find this tidier than messing with those nasty bottles and their gunky dropper tips; and it's easier to hold the PV in one hand and the drip tip and the syringe in the other. Pull the plunger back after dripping and there is no way anything will leak. I realize how weird it must look, though...
