Monkey

Welcome fauxsmoker! I'm new here, too. Lots of great info.. hope to see you around

I personally always add a sweetner to my liquids, but of course many don't like them that way. If you do any DIY you can control your flavors much more accurately, and save money in the long run. If you find something you can vape all day, run with it.

The "food grade" isn't a big issue, just buy from reputable vendors/someone you trust. Some of the internationally shipped liquids have been known to be of subpar quality...with other things possibly mixed into the liquid. Always be sure that what you are vaping is safe, we want this to be HEALTHIER than smoking...not worse.

Ya know... I used to vape 100% PG for the longest time with no ill effects... recently I have started doing a mix of either 60/40 or 50/50 because I've been dripping more. And you know what is crazy? I have honestly been getting headaches more as well... I truly think that it's the VG! They aren't terrible headaches... just enough of one to be bothersome/annoying though. I don't know... I think some more investigating is in order to get to the bottom of it.

got a bit bored just a min ago and came up with this...

ya, you'll find VG flavors/liquids will always be a bit sweet. But then again, so are a lot of the PG flavors.
Liquids are a lot of trial and error until finding the liquids that really work for you.

My experience with food grade is good. Its a bit sweet and the consistency of VG liquid.

The second option is pharmaceutical grade....sold usually as 'skin protectant'. Most pharmacies carry it. once such brand is 'Humco', I know, the whole skin protectant thing is a bit weird for vaping, but it really is just VG.

I personally have used both and both work great.
If it doesn't specify it is probably PG.

Hi!
As a vaper, I have found that the market is very 'loose', with no kind of regulation at all, and I decided to start researching about what I vape.
First thing, of course, is the easy one: nicotine concentration tests on e-liquids.
I decided, though, to purchase the ingredients locally, for many reasons - paranoid customs officials in my area being not the least of them.
I have a few questions for you:
1. I found Bromothymol blue in the powder form. I was told that the solution should be made with 0.05% Bromothymol powder and the rest distilled water. Is this ok? If I make it much denser, will there be a problem? (I don't have equipment to accurately measure weight. I use a cheap digital scale with 0.1gr precision, but I know its readouts are not precise).
2. I think that using an even less denser sulphuric acid solution, like let's say 0.06%, can lead to even more accurate results, since the inaccuracy associated with the 0.1ml marking will be cut in half. Is there a reason for not using that much thinned solution?
3. I purchased Sulphuric Acid at 96% concentration (nothing less at the local market, sorry). I will make a much less dense solution for making the tests, about 1 gram in 830 gram of distilled water to be close to the 0.12% you are using.
The problem is, of course, derermining the actual concentration of the solution. If I know it, I'll be able to decide the number needed for multiplication , to determine the actual nicotine content.
Can you tell me a way to determine the concentration of that Sulphuric Acid solution? Is there an alkaloid product on the stores, with standarized pH, to make a test using the Bromothymol blue so as to find that concentration?
Alternatively:
I'm thinking of thinning it in 3 steps, using e.g. 10 percent of the solution in each step with 90% distilled water.
So it should be:
Step 1: 90gr water, 10gr Sulphuric Acid 96% -> 9.6% solution
Step 2: 90gr water, 10gr Sulphuric Acid 9.6% -> 0.96% solution
Step 3: 90gr water, 10gr Sulphuric Acid 0.96% -> 0.096% solution (which is a number close to the 0.12% you are proposing, and so little changes have to be made to the calculations. If I use 10.76% and 98.24% I will end exactly at 0.12%).
I believe that using my cheap digital scale, I can achieve 0.2gr in 100gr precision. So, with 2% inaccuracy in each step, the total inaccuracy will be a bit less than 6% (and the final solution will be somewhere between 0.090% and 0.102%). In a 24mg liquid, the results should be between 22.59mg and 25.47mg - and on a 6mg one, between 5.65mg and 6.37mg. That's enough precision for me.
The question here, is: Is this correct? Did I forget something fundamental - or trivial - that I should take into account? Is there a practical consideration I don't know, or a mistake in my assumptions or calculations? Perhaps Sulphuric Acid's molar mass or density should be used somewhere?

And, finally: why not put the Bromothymol blue in the sulphuric acid solution, so that only one bottle will be needed for the test?

I hope that all these are clear and understandable, since english is not my native language and I'm not a chemist.
I also hope that you don't hold hard feelings for not purchasing the supplies from you
Finally, I hope that this post will be noticed and replied soon...

Best regards from (tottering at knife's edge) Greece!

Woow Jeff... that made me jump back from my chair... lol... Welcome to the forum Monkey. I started off with the Ego-T almost 8 months ago, and was my first PV. I was happy with it. I use it for 2 months.. Then I switched over to cartos, then cartos Tanks... I still used the ego batteries though.. very good batts... I now use variable voltage mod, and other basic devices... Playing with toys is part of the fun.

Ok, Jeff....that really and truly did make me laugh !!! I want one.....

Welcome

Welcome !!! sounds like you are off to a good start. Research is always good, sometimes you just have to jump and you jumped very well. Like you said, it certainly won't be your last set of devices. vaping is its own addiction, less so the nicotine, much more so all the cool toys !!!!

hello and welcome to the forum

Welcome. I've been using the Ego-C since it first came out a few months back. Have some patience, as there is a bit of a learning curve to using a tank system, but overall I'm satisfied with it (at least for now). I'm by no means an expert, but if you have any questions, I'll do by best to help.

Welcome to Vapor Talk, lots of helpfull people here so you found the right place

What a great forum, hello

I decided a couple weeks ago I had to quit smoking... 15 years at it, pack a day =/

So, after reading up, and "binging" on youtube video reviews for days (my yt favorites list looks like a vaper's convention now).. I settled on a couple tank systems.

I'm sure they won't be the last I buy / try, before finding the right one. I hope I can figure things out and look forward to learning from all of you!
