How many drops in a 15ml bottle?

[sbphotog]

Aproximately how many drops can you get from a 15ml bottle of juice?

I read somewhere that you get
1 tablespoon = 3 teaspoon = 15 ml
1 teaspoon = 120 drops of water = 5 ml
1 teaspoon = 60 drops of thick fluid = 5 ml

The juice I use is thicker than water, but not a whole lot thicker.

So by averaging between the two above I get about 270 drops per 15ml. This of course is an estimate.

has anyone ever counted or kept track of the amount of drops in a bottle? It would be nice to have something more than just an educated guess to find out how long a bottle will last.

Just started a new 15ml!!!!!!! I'll get back to you when i'm done

Well, this is the educated guess you didn't want. But a general rule of thumb on this forum is that 20 drops of juice = 1 ml.

That goes along well with my estimate. That means a bottle will last me 10-15 days at the rate I drip.

Thanks

According to the calculator below 1ml = 20 drops. So 20 x 15 = 300. I do not wish to actually count 300 drops however so read on

eJuice Recipe Calculator

Having said that I would point out that not all drops are created equally as the size of the end of the dropper being used does affect this.

If you have a measuring device that is graduated in ml, you could test your bottles yourself by counting the number of drops required to reach 1ml and multiply accordingly. (like I did above)

If you wish to be more accurate you could get a glass eye dropper and use it for all your drops, this would remove the random size difference between various botles.

Easier still would be if you wish to mix a set ammount of liquid ( like a 30, 20 or 10, ml for instance ) use a graduated pipet or syringe that is marked in ml to begin with. Ofcourse this method is only godd for an end result greater than several ml, for lesser ammounts, like 1ml I am afraid we need to count drops still.

If you don't have said items, I am sure a graduated syringe is available at any drug store, and possibly the pipets as well. Or you may consider a diy kit like the one I ordered from Dawn here: http://www.diyflavorshack.com/default.asp

Thanks NightShadow! that was very helpful

Would it have been easier to just figure out that you use on average about 2ml a day so that works out to about a week per 15ml.

if the lid is off one drop

if the lid is off 20-40drops = 1ml

I agree,

The number of drops varies widely with dropper and liquid viscosity.
To be close you must count the drops in a teaspoon or other measuring device.
If you don't, you can be way off the mark.

Thanks for pointing out viscosity also affects drop size! In my attempt to be less long winded I left it out unintentionally.
