Nic Base Storage: Freezer vs. Room Temp Experiment

Thank you! Called a local herb shop & will take a bottle or 2 with me.
I have 2, 4 and 8 oz bottles (from Packaging Options Direct). Do they have the same neck sizes as 30, 60, and 120 ml bottles?
We really should just bite the bullet and switch to the metric system.
Not all. I have 0.5oz, 1oz and 2oz bottles that all take 18mm (18/400 caps)
Phenolic Cone Cap - 1/2oz & 1oz (18mm)
Heartland also sells 1 oz caps in 20mm (20/400)
Phenolic Cone Cap - Older 1oz (20mm)
One “last” question: does nicotine base of PG or VG) expand when frozen? Should I leave a bit of room in the bottle? TY!
No.
And I don't know about VG, but PG actually contracts (if that's the proper word). I still leave some headspace though. I don't go past where the straight of the neck starts (see pic). But this is just what I do.
PG and VG have a freezing point of below -70F and -30F respectively.
Keep in mind that the polycone insert inside the cap will need a little room since it goes into the bottle opening a little (kinda like a cork). So you don't want to fill it full or else when you close it some nic will gush out.

You should always leave some headroom--~2 ml. Not because of freezer contraction, but because of the ambient temperature of the room in which your nicotine was bottled originally. If you filled your bottles in the winter when the ambient temperature was, say, in the 60s, and then open said bottle on a hot summer day, your nicotine base will expand and you'll have a big mess on your hands. I always use a cookie sheet or something similar, anyway, just in case. Easier to clean and much safer. I also use funnels to transfer my base from bottle to bottle. Good luck!
That's really helpful. I have a bunch of 30ml boston rounds. I made the mistake of soaking the caps in soapy water to clean, but the water ended up getting inside the polycone inserts. I tried popping off the polycone inserts to clean them but cracked quite a few.
Does anyone know if you can just get the polycone inserts that go right inside the cap? The caps are so cheap though I think its not a big deal if they don't sell the polycone inserts separately.
Yikes. I filled all my 30ml nearly to the brim, just enough room to allow the polycone inserts to push in the bottle without spilling nicotine solution out the sides. I figured if there is no air in the bottle, that's best.
Maybe I will open them in the refrigerator when I need them in order to "burb" them.
How many bottles are we talking about? If just a few, I'd probably pour out a little (1.5ml) from each bottle and recap. Or, like you said, defrost in the the fridge and hope for the best. You'll probably have some spillage. Put something under the defrosting bottle to catch the overflow, just in case.
Maybe others will chime in with advice.
I can attest to not filling completely and leaving at least the bottle neck empty with air or argon gas. I'm the only I know that had this happen to, but it did happen to me. I filled 1 liter bottle/s to the top with room temperature NIC and then screwed on my polycone caps. I then placed them in the freezer and within a few minutes I heard popping sounds coming from the freezer. The bottle/s cracked in half. Not tiny cracks in the glass, but literally fell apart. Might have been because they were full liter bottles (32 oz amber glass) and not smaller 120ml bottle/s but none the less... lesson learned.
That sounds like a stress fracture from the cooling of the glass itself in the freezer. My guess is that there was an invisible defect in the glass and just placing it in the freezer was enough of a rapid temperature change to break the glass. I am thinking that a few minutes is too short of a time for all that liquid in the bottle to do much.
I have this happen with canning jars sometimes. Granted that's boiling water.
It brings up a good point though. Maybe when I get new glass bottles, I'll put them in the freezer first to see if they pop.
I just checked all the 30ml bottles in the freezer, about a dozen, they all look fine. I just placed one in the refrigerator. Will see what happens. If I'm ambitious, I'll put it in a warm room as well. If it still looks good maybe I'll tape it to the hood of my car for the sake of science.
I think next time though I'll leave a little room at the top just to be safe.
Put them in the fridge for a day/overnight to get them cold, then put the in the freezer.
Just a thought. Never bothered myself.
