Exact Measurements and VG

[mrmack00]

can anyone provide tips for more precise measurements? I'm using the Breakthru calculator - which is awesome - and it provides great measurements in terms of ML's and drops. I've read that using drops is not an accurate method, so I refer to the ML's listed on the calculator. I'm trying to make tiny batches first, to make sure i like a flavor and get a good mix; however, the measurements I'm using are so tiny, like .14 and .27 for example.

the 3 Ml and 1 Ml pipettes I'm using only have measurement ticks for .5, 1.0, 1.5, etc...Trying to guestimate .14 or .27 is guesswork, at best.

Is there any way to obtain more exact measurement when trying to make small, test batches? I've heard the pipette pumps are better; however, they still include the same measurement ticks. What makes them better?

Also, I was guestimating a test batch, trying to obtain an 80pg/20vg mix, but the VG is so thick..I've heard that can be diluted with distilled water. How does that factor into the calculator?

Any tips would be greatly appreciated.

A 1ml/1cc syringe is slim enough to go into flavoring bottles without a needle and has graduations in 0.02ml. So if your eyesight is good enough you can stop between graduations and get even closer.

Most graduated volumetric syringes are accurate enough for DIY purposes. A 10 mL one can be accurate to 0.02 mL if used properly. Way easier than drops too, which are indeed VERY inaccurate, and should never be used for diluting 100 mg liquids. A good syringe will run less than a buck in price.

I use the 1 ml syringe for flavorings, 5 ml syringe for everything else or lately a glass graduated bomex stuff from Wizard Labs for larger amounts.

Drops can be effective in small batches if you first take the dropper of your choice and drop out how many drops it takes for that dropper to reach 1 ml and then you can change it in the calculator section that says ___ drops equals 1 ml. Then use that for the small test batches.

You can also take an amount of flavoring, and cut it with pure PG/VG. Say 50/50. You can then use double amount of flavoring, which should make the measurements more accurate.
