If I'm making a bigger batch (100 ml or more) I have a graduated beaker and a milk frother. Put your ingredients in the beaker, insert milk frother and turn it on and watch it go. Stirs up the mix in a couple seconds and introduces a lot more air than shaking does. Once I'm done mixing (30-45 sec) I pour it out of the beaker into whatever size(s) I need to fill.

The typical dropper tips like you find on all common PET and HDPE 10 to 30 ml plastic bottles will work with early gen kayfun fill ports. Trick is to aim for the center and apply pressure.

Haven't tried with the unicorn bottles, retired my Kayfuns before Unicorns came into vogue. The ones I have are tapered and look like they might work using the same "apply pressure" technique.

Rounded tips, like the ones that come on the wider mouth plastic bottles (like the style Capella uses for their 13 ml flavorings) will not fit a kayfun port. I have managed to fill Kayfuns with this style of tip (push hard into the port and squeeze) but it's messy at best.
Thank you!

@Eskie...Can you fill the kayfuns with the unicorn bottles?? Does the needle tip fit into the fill hole? and where do you get yours?? Thanks
I top fill my kayfuns. Its a bit tricky but once you get the technique down its not so bad. No more having to deal with a tiny screw I keep losing.

Thank you!
You are welcome!

For what it's worth, Another little tip, regarding transparent "PET" vs. natural "HDPE" for refilling Kayfuns. Ordinarily I tend to prefer PET. I like their crystal clear transparency and they seem to clean up a lot easier than HDPE. HDPE seems more prone to retaining aromas. Maybe because HDPE is more porous? I also like PET's higher rigidity, especially when snapping on the dropper tip. The neck of HDPE tends to cave in (thereby forcing liquid up and out of an overfilled bottle :) ), while PET always holds its shape. The only bottles that have leaked on me when tossed carelessly into my bag are HDPE, and I suspect it's because of their lower rigidity and proneness to becoming deformed when squished under other objects.

The downside to PET is that they are harder to squeeze, and under repeated use they develop a crease around their middle. I've got PETs in use that have survived hundreds of refills, and I've yet to have one crack or spring a leak, but the creases make them appear pretty beat up. The PET bottles that we can buy cheaply in bulk are actually thicker than ideal. What we need are thinner PET, or PET that have a thinner middle area for squeezing (like Flavorah's bottles).

Anyway, it's more difficult (but still totally doable) to refill Kayfun ports with PET. Since the standard dropper tips aren't small enough to actually enter the fill port, what you have to do is apply pressure to create a seal and then "inject" liquid into the tank. I've learned it's much easier to do that with the more flexible HDPE bottles.

Thank you very much. Good information. This is obviously a well thought out reply and I appreciate it.

@B2L - You might want to check out GlassBottleOutlet.com the next time you're looking for glass bottles especially. Many have found that their overall total price, including S/H, beats out POD by a long shot. Since they're also located here in FL (Sebring) your S/H should also be lower than from POD.

@CDATundra - You might want to look up little bottles like in the link below. I ordered those 5mL ones, and then just used the caps on my 10mL-50mL plastic bottles I keep eliquids in to fill my KFL tanks. I never have any problem at all, because the blunt needle goes down into the tank.

I bought these when they were on sale on FT. They have other sizes, too, but since I wanted to just scavenge the caps from them...I went for the cheapest size. In the US, most vendors want at least $.75 each for EACH cap!

As far as plastic bottle types, I personally won't leave any eliquids, nor ingredients for them, in any plastic bottles except #2, #4, or #5. Those are the only ones that will NOT leech plastic into the contents, and can be safely reused. That's 1 reason they're the types used in most plastic things manufactured for use in the medical and scientific fields.

The #1 PET bottles are not rated for more than 1-time use. They are not one of the types that won't leech into the contents.

I have lots of glass bottles from all over, brown, cobalt blue, polycone top, and dropper. I HATE the droppers. I always make a mess with them filling a tank (OK, not a mess mess, but a few drop on the side, or worse the mod). So I use glass for mixing and storing. Stuff I'm vaping go into 30 ml plastic unicorn bottles that make refilling a 2 second affair (as long as the top cap isn't stuck in too tight).

I've looked at the unicorn bottles and was tempted to order some. Do they stand up without tipping over easily? I bought the 60ml LDPE bottles because the wider base looks more stable, especially when filling.

The do stand up, but obviously can be tipped over. But with the dropper tip in place you won't have any leaking unless you squeeze the bottle while it's on its side. And it has the extra cap that screws over, so you can toss it in a bag or pocket without worrying, short of maybe crushing it, about a leak.

Edit: to be sure we're talking about the same thing, they're all a variant on this. Note the little cap to fill and a separate top cap to close it all up

It would definitely be convenient in a pocket. I keep a 15ml needle tip bottle along with a battery and a keychain screwdriver (in a zip lock) in a tiny zipper bag the holds up to three batteries when I'm out and about. I'm good all day with that as a backup if I start the day with a full battery in my mod.

Not sure what your juice is at, but for me at 70VG, those needle tips aren't all that helpful. If they were 14G, sure, but they're not. I also only vape ~5-7 ml a day, so even out all day, I never really run into an empty tank or run down battery. If I'm not sure when I'll be home I'll throw an extra set of batteries and a unicorn bottle in my pack just in case, but have yet to need it.

The only time I have to be careful with my unicorns (15 and 30mL purchased from One Stop DIY Shop) is if I am mixing directly into them. In that case I have found that I can place the bottle in a shot glass and then it can't tip over.

The only other limitation I have noticed is the opening is pretty small (+/- 9.5mm/.374in.) so it is not friendly to most frothers if used.

Other than that they are indeed very convenient; fitting nicely in a pocket, narrow tips that will fit anything I own, and have never had a leak issue (again I can only speak regarding the OSDIYS bottles).

I'm pretty well stocked up but if I find I need more I'll check them out, thanks :)

I don't think I could deal with mixing right into a unicorn bottle. Tried it once and no more. Besides, I prefer making 60-100 ml at a time. Mix and store in glass, and refill unicorns as needed. That' the workflow that's fits me best.
