Reddit reviews Premium Vials B36-pk12 Boston Round Glass Bottle with Dropper, 1 oz Capacity, Clear (Pack of 12)

Do you happen to have a vitamin shop or a science supply store near you? I believe both of those should have similar caps, but I'm not sure about the specific threading and sizes.

Also: http://www.amazon.com/gp/aw/d/B00I4BQXVW/ref=mp_s_a_1_13?qid=1459307392&sr=8-13&pi=AC_SX236_SY340_FMwebp_QL65&keywords=bottle+cap+with+dropper. Though that is a 12 pack of both bottles and tops. There might be something in the recommended section?

I buy mine on Amazon Prime. I probably pay a few bucks extra but I like Amazon and I love my free two day shipping.

I transfer all of my flavorings in to 1oz glass dropper bottles. My VG, PG, and nic are transferred to 8oz squeeze bottles so I can easily add it to my mixes. There's no waste, nothing to clean up, and I can make a 20ml batch in just a couple minutes and a 125ml batch in only a couple minutes more.

For recipe calculation I just use an Excel sheet where I have every flavor's specific gravity referenced for use in a formula to automatically adjust for my batch size.

I really don't think it could get any easier than this.

I use a 30ml (1oz) dropper bottle. Recipe:

•put 4ml propylene glycol into bottle

•add 1g 4F

•put thumb over bottle opening and shake vigorously until completely smooth, with no lumps. Might take a minute.

1 drop is 5mg. Shake well every time before use (product will settle out).

Boston Drippers

I've purchased these a couple of times. Good price and quality.

Edit...there were 5 left in stock when I posted....down to 3 now.

For storing paint, i often keep my most used colors in these.

that way i can mix drop for drop. If it is not in one i usually just eyeball it. Sometimes use droppers, or just pour it out of the jar. Never really had a problem. After a bit of painting/experience you'll be able to eyeball it.


The only time you should have have color consistency problems is if you are mixing a custom color. Otherwise you should be fine. I usually mix half a cup and just keep add/mixing more in my cup as i go til i finish the project.


2nd. I usually always mix it in the cup by putting a paper towel lightly over the tip. This should cause bubbles to go back into the cup and mix the paint. (this can get messy it you have a lot of paint in the cup.


If you are using acrylics, i would suggest you getting a retardant or a flow aid. This will slow the dry time and decrease tip drying. This is insanely helpful with some acrylics. They also make retardant for lacquers ect. Just make sure you have the correct one, acrylics is the most useful.
