Just saw this. Tuned in still, time allowing. Mike and I have been communicating directly, but I have not been on the thread for a bit. It was an original Subtank, not a mini. I don't know what resistances the subtank coils are now, but at the time of our study 0.7ohm was available, and may...

Mike, so far it LOOKS like everything, within the parameters of the equipment, is being accounted for, and I applaud this heroic effort. :thumbs: Once you start getting ppm (or ppb) and can calculate back to actual micrograms of formaldehyde per puff and per gram of e-liquid consumed, then we...

Been a bit since I was on ECF, so just now trying to catch up. Interesting video, and no, I was not aware of these formaldehyde determining devices. That said, even though the experiment was not very rigorously carried out, the results were interesting and perhaps comparable to our published...

MPG and PG appear to be the same compound, with both having the CAS number 57-55-6. The mono here implies it is not a dehydration "dimer" of PG, or it is the monomer, meaning precursor unit used to make the dimer. For example, there is ethylene glycol, HO-CH2-CH2-OH, and there is diethylene...

Well, I'll be! Adam, how the hell are you?!? Has to be you, doesn't it? Outstanding to hear from you, one of the true pioneers of e-liquid. I sure do remember that dinner in CC, with the waitress asking us if anyone was smoking, and us innocently shrugging, hiding our little 510s. And I do...

Not a fan of benzoic acid inhalation myself. Don't know what it does in the lungs. Sodium benzoate is a preservative with anti-mold and anti-bacteria qualities, but it may be carcinogenic: Sodium benzoate is a preservative that promotes cancer and kills healthy cells I don't think it is the...

If the substances are miscible, they will not separate, unless concentrations or temperatures change enough to change solubilities. Oil and water are not miscible and not an appropriate example here. Nicotine and PG/VG are. Salt is more dense than water, but will not eventually fall to the...

ECBlends is a certified AEMSA member, and thus are bound to nicotine accuracy for all of their e-liquids. Their lab results on nicotine must be within +/- 10% of the labeled value for all of their e-liquid products, and documented as such. If you think their nicotine is inaccurate, you should...

Yep, 5.5 years for this thread. Still very relevant and valuable. I always look first for the horse in the DIY forum to see if there are any new discussions. There is a lot of history here, and Cyrus, you started it! :thumbs::toast:

Wondering what the opinion is of the new VapersTek Throat Hit nicotine. It is no longer Chemnovatic slightly oxidized, as it was for years. It is a different nicotine that does have more bite than Chemnovatic.

I think that is the tobacco base he used for his Maple and Vanilla Tobacco e-liquids. Not the same as the Tobacco flavoring, which is evidently Mother Murphy's Artificial Burley Tobacco Flavor. But looking into that, seems regular consumers do not have access to either that flavor, or flavors...

Also, WL Ice and Ultra were identical to me, but I recall WL saying they were from different sources.

I did think that WL Ultra was Alchem, but that is just because Alchem back then was the only Nic source I was aware of doing the post-extraction distillation step. Could be other nic manufacturers were too. I dunno. I never titrated it, but I doubt it was a salt solution, since WL was a main...

Wow. I find it fascinating, to say the least, that after talking highly of VV nic since 2009, there is suddenly a real interest in it! I didn't look recently at their website, and I am VERY sad they closed. Adam was one of the real pioneers in retail vaping, offering the first bulk DIY nic...

I would not have said this a few years ago. I never had anything that old, which would be from 2007/2008, and I was not vaping then. The oldest I had was from Fall of 2009, so about 7.5 years, Vermont Vapor but that is all vaped now as of this year. It never changed at all. Oldest ones I...
