When I worked in pharmacy we used to have these bottle cap adapters for oral medications. Like this. They could be used with oral syringes (no luer lock on them).
Does anyone use anything similar to this? If so, what supplier(s) do you use for your VG, PG and nicotine? I ask because the bottles I have from Wizardlabs.us do not have a diameter that would fit any adapters that I was able to find.
If you're wondering what the purpose of the adapter is, it makes drawing liquids MUCH easier. You tilt the bottle upside down, so gravity is helping you slightly. I'm just damn tired of drawing up 15mls of VG and having it take 3x as long as PG.
Sorry I'm not familiar with those. However if you start measuring by weight and put your bases in drip bottles, you won't have to worry about drawing into a syringe
If you have luer lock syringes you need a luer lock cap! Found the bottle+cap, didn't look too thoroughly for just the cap though.
