Are you telling us that you are indeed in possession of 100% nicotine??? If so, how did you even acquire it?????
Or are you taking your 10% (100mg/ml) to a lab? If so, that's an overkill. You don't need to get suited and use a lab to work with 10% nic.
That said, this is a third or fourth post (in the last couple of weeks) by a new vaper asking for advice how to handle 100% nicotine. I didn't even think a civilian could get 100% nicotine.
I've been getting some through a Lab BUT I don't touch it and it goes straight to the Lab. I believe many are mistaking the purity of the nicotine juice rather then the potency/ mg IMHO.
