How do we know it is 99.9% pure?
Me personally ?
I trust the vender based on my dealings over the last year.
For others shoot them and email with your concerns and see if they they reassure you as they have me
How do we know it is 99.9% pure?
Ever get the feeling, your'e in a dark room with a bright light shining directly in the face? What day did it have no taste ...LMAO!!! Gimme a break!!!
Anyone that is concerned abou color change with nic may want to read the thread about it by two very reputable chemists here http://www.e-cigarette-forum.com/forum/diy-e-liquid/86000-word-about-nicotine-purity-storage.html
This is the first post
A word about nicotine purity/storage
Much is made of trying to find the optimal storage conditions for nicotine concentrates to be diluted into working eliquids. Similarly, much is also made of finding concentrates with good pure nicotine.
These are good things, but ultimately, I wonder how much they really matter.
Consider this image from Exogenesis. This is from his vapor trapping experiments where he set up an apparatus to auto-vape e-liquid and electrostatically condense the vapor for nicotine determination:
On the left, you see eliquid made from pharma grade nicotine. On the right you see the same liquid after it's been atomized and condensed.
No matter how well we source and store the stuff, the stuff on right is what we're vaping, not the stuff on the left. After all, the last thing we do before we inhale our precious liquid is heat it up aggressively in a stream of air containing about 20% oxygen.
I'm not out to make a big deal about this inescapable fact of vaping, but it's at least something to consider when we might be tempted to worry excessively about our concentrates getting a slight yellow/brown tinge.
Thank you!!!!I don't buy this,,, that's like saying we all eat ketchup, but we can eat the ketchup that we purchased this week or the bottle that's been open for 3 months,,,, I want to eat the fresh ketchup Salem
Uhh...Read post #98 again...I've already answered the question.
I sure hope so. All of my best nic bases are Chinese.I would bet you that the VZ Nic Base is coming from one of the same places others get theres too Jimi D
Salem, my only point was just that, Fresh is best ( of a high quality Nic ) and for storing it the Deep Freeze is the best way, thats all. No pun intended buddy, just stating what I have experienced in my time with handling it.
BTW- I sampled VZ nic. It was not bad but I did detect a slight odor and taste. That is just how it tasted to me. It did not make it bad and I had no problem using it.
Since you brought it up....
I bought 2 different bottles of so called usa nic in last year and both turned a dark shade of yellow in about 30 days
