For months I've been doing something stupid.
I'll buy 500ml/1litre bottles of PG/VG. I'd take the needle off to suck up the VG but when it gets past a certain point I had to put it back on to reach the liquid, which is slow as fuck due to thickness.
Then once it reaches past the needle I was fucked. I'd pour it into jugs and things.
Just realised something obvious - take the plunger out of your 10ml/20ml syringe and pour the bottle directly into the syringe. Then you can stick the plunger back in and fire it out. This may be obvious to some but I've just realised what an idiot I've been.
Hope this helps someone.
Similarly: when I started keeping my nic solution in the freezer, I soon realized why people use 100mg base. If I need 5mL of nic, I can basically watch Dune before I get it out of the bottle.
A cleaner way that works for me is to cut the bulb of a disposable pipette disposable and put it on the end of the syringe like this; works beautifully.
On a related note if you have one of the needle tipped flavouring bottles, instead of removing the tip and trying to syringe out your flavouring amount you can instead turn the syringe upside down (with no needle attached) and pull the plunger to the required level. Then simply insert the bottle needle tip into the end of the syringe and fill.
Just note that you won't get the right amounts using this method.
I don't understand why?
Because it won't account for the juice in the needle. Try pulling some water through it and you'll see some air between the rubber thingy and the liquid, and that ammount of liquid will be in the needle
I just pour it into a smaller container like an ounce glass or small measuring cup and syringe it out from there. It can't be any easier.
