I have a 30ml bottle of 72mg nic, 100% PG. I've calculated that I can make 24 3mg 30ml bottles of juice, before running out. So far, I've made about 10 or 11 30ml bottles, which should mean that I've used half the bottle. However, when I take it out the freezer, it looks like i've only used 1/4 or so. Also the stuff is really thick, slightly thicker than VG is at room temp. Is this to do with the stuff expanding due to being frozen or what? Furthermore, with the most recent batch of juice, I made it 3.5mg, but it doesn't feel like I'm getting as much of a kick as with the previous 3mg batches; although this could be due to me overthinking about it.
Edit: I think I now know the reason why. I took my bottle out of the freezer last night, and checked this morning; it is now at room temp and seems to be as thick as VG, so I think they messed up and sent a 100% VG one. This now explains the why, as I assumed it was 100% PG (which is what I ordered).
If your measurements are correct then that’s all that matters. I’ve never heard of PG expanding when exposed to freezing temperatures.
Also, 30ml is working bottle size. there’s no need to put that small amount of nic in the freezer. going from cold to warm 24 times (24 bottles) is not a good idea. A cool dark place is fine enough. I kept 120ml of 48mg/ml in a drawer for over a year and it didn’t degrade or oxidize.
The only thing I can think of is they gave you extra nic. I ordered 1 oz boston rounds (29.5 ml) for my nic but they actually held close to 50 ml so you can have some head room. Maybe you got a 40 ml bottle and they just topped it off.
Hi. How are you measuring your nicotine, by volume (ml) or weight (g)?
Both. I'll take roughly the right amount into a syringe, and then put it into the bottle, which is on a scale. Also, are you meant to wait until the stuff completely thaws out, because I've just been putting it in when it's still thick.
You need to get it to almost room temperature to use it. It needs to be mixed well otherwise you'll have nic hot spots in almost frozen PG. As it cools down it will become thin. Don't use it frozen.
PG doesn't expand when cold.
Nic base coming out of a freezer should be given a day to adjust to room temp before opening, so you don't get condensation inside the bottle when it is opened.
As to whether it should be stashed in the freezer, it depends on how quickly you run through it (how many mg of nic per day you run through), and the storage environment. My working bottle (the one I use for mixing) has about one year worth of nic in it. I will open it about once every 2 - 3 weeks for a round of mixing, have it capped except for the brief time it takes to pull some out. The bottle itself is glass, brown, in a basement that normally has the lights off and stays at about 65-75 degrees F. By the end of a given working bottle the nic inside it shows little degradation.
Agree on all. I have 2 liters of 48mg 100% VG in 1 oz Amber Boston Rounds in my freezer. Light and air are nics enemy. I keep a working bottle in the fridge but leave it out until room temperature prior to mixing. That’s important. If I buy a new liter I keep mine sealed in the the light deterrent bag it comes in stored in a cool dark place until I’m ready to transfer to 1 oz. I’ve heard of nic stored in the freezer in this fashion lasting several years. Anecdotal so I hope it’s correct. I stocked up due to the crazy tax legislation I’ve heard of here in the US. Now I have a question. What is the advantage of PG?
>What is the advantage of PG?
It's just easier to work with.
How are you measuring?
