That BE thread is huge..
Here's what we do.
We buy 99.9% nic from a source in China(sorry, but nobody gives out their source of nic. But it's not BE.)
We then mix down to a PG or VG 300mg base for making our
e-liquid.
We use precision droppers and have calculated ratios for the number of drops of nic base for the proper size of bottle to get the proper percentage of nic in a bottle of e-liquid. The total concentration of nic can be off slightly due to variations in the amount of base that is used but it is minimal.
Our nic comes with lab tests. We also test batches of 36mg nic made from our 300mg nic, to make sure that it is accurate at the highest concentration we sell (36mg). Our last test results on 36mg e-liquid came back at 39mg or 3.9% instead of 3.6% (a .3% variance). We also test for DEG with none found.
We started using 99.9% nic back in May of 2010 because we too had doubts of the accuracy of the VG or PG nic solutions we were buying. Testing was within 2% of what we the mg was supposed to be but it still wasn’t close enough for our standards.
With 99.9% nic, we have much more control of what we produce but at a cost. We have a ventilated room, safety gear and precision measuring instruments we use when making our 300mg base. We are also hazmat certified as well as FDA registered. It's a hassle but worth it for our own satisfaction as well as yours.
With eyes upon us all the time, we do our damndest to make sure that the product we sell complies with anything we can find or think of.
