terribly confused on ml sized bottles

[v4l555lover]

I just did a mixture of liquids into a 30 ml bottle . half from source A and half from source B . going by 100 drops is 5ml i put in 300 drops from A and 300 drops from B . B was a brand new bottle of 20 ml , the bottle is still 3/5 full and to my opinion should have been 1/4 full . am i just not counting right or is my math off ? or could it be we are getting A LOT extra ?!? has any one else tried this ? just very curious to know...

I found the "drops" method to be completely inconsistent for me. I was trying to play around with some new custom flavors, and tried counting drops... and it turned out be WAY off. Could've been the different size of drops depending on dropper/bottle/etc. Now I only use a syringe to measure it out, comes out like it should now

A lot of places will use a say 50ml bottle, but fill it up so you end up getting like 20% extra. I never count on it, but it happens a lot.

Also, you might check drips per ml for each A and B. They may be different thicknesses.

the drips method is actually quite inconsistant... usually i just keep in mind that 1cc is 1 mL and use a syringe to measure thusly...

The dropper method is quite accurate at lower levels BUT you must use the same dropper for you liquids and you must see how many drops equal 1ml. Some are 20 drops = 1ml some are 40 drops = 1ml. Always check and see how many drops your dropper takes to equal 1ml. Then you can gauge quantity accuratly.
The more ml you tests the dropper against the more accurate your quantity will be, i.e. my dropper is 205 drops = 5ml. I always use a syringe and drop into that to check drops per ml, every eye dropper is different, as is the viscosity of the liquid.

Syringe for me also. I don't like surprises when imbibing anything.

Where does one get a syringe since the drip method is so inconsistent

[Dkrom68]

DIYFlavorshack has them and alot of local pharmacies do as well no script needed. For 10 Ml batches I us a 10 ML medicine spoon drink cup thing you get for kids just pour quantities in and done

I ordered a doubler and a 48mg from TV and all I did was fill a a 30ml bottle with half amount of each to create a 24mg strength bottle. I just eyed the amount not actually measure drop by drop.

Be aware that the ink used to mark syringes is very often PG and/or VG soluble. So, you can lose the markings if you get some juice on the outside.
