If you're now at the pro-level, CXTC offers their fabulous nicotine with a dispense pack kit (CO2). This means your nicotine never touches air (until dispensed) and you can store it at room temperature for a year.
The dispense pack is $125 which isn't too shabby. You'll need to source CO2 locally.
You can also buy 11 liters of their high grade nicotine for $1592 (plus a bottle deposit fee).
While 11,100 ml of 100mg/ml nicotine sounds like a lot, for a professional mixer it's easy to use it all in a year if you mix just 100 30ml bottles a day!
And no complaints about oxidized nicotine ever again.
If I'm reading this correctly, both the product title and the picture of the keg say 100mg per 1000mL.
That's only 0.1mg/mL... Am I missing something?
That's not how you interpret their crazy labeling.
Don't ask, I just work here.
It's 100mg/ml.
this is all homebrew equipment. Not like 'they made it up themselves' but like LITERALLY: I can buy this at the brew supply store in town. I don't know what the dispensing nozzle looks like... and I know that internally that comes in to contact with brass...
I wonder if there aren't smaller systems that might not work better for home storage
Very probable. I'm working on a home dispenser myself but I have issues with the diluents. PG and VG don't flow like water (VG worse of course).
I wonder if a party star would do well in the freezer:

it's 5liters, so still kinda big... but I guess you could mix 100mg down to 20mg base, keep that in the freezer, and pull off 50 or 60mls as needed
