For travel/camping, centrifuge tubes also work really well and come in a variety of sizes. They’re usually around $8 for 50 on Amazon. I also use them for small amounts of medicine. A 5ml tube will usually hold 6-10 ibuprofen, benadryl, etc.

What I usually do is take the J Herbin bottles and dump the contents directly into a 50 ml sample vial (Amazon). This way I don't have to limit myself to bottles that are actually designed with the use case in mind.
If you love Perle Noir, then this is an inexpensive way to keep using it effectively.
EDIT: As a bonus, J Herbin labels peel fairly nicely, allowing them to be transferred directly on to the vial.
Yeah dog...
These are the tubes I use
This is the rack I keep them in
Nalgene bottles or 50ml sample tubes.
Here's a post I wrote detailing how I slant yeast. The process is pretty simple, and only requires mason jars, test tubes, an innoculation loop, stove and pressure canner and a few consumables. I've tried several other methods for storing yeast, but this is by far the easiest, cheapest and most compact. You only need a pin prick's worth of yeast to create the slant, and you only have to maintain them every 1.5-2 years (which is also very simple). This makes it so you can accumulate quite the bank! I currently have a bank of 23 yeasts, and it fits in the size of a shoebox. The only thing I will note is that the test tubes in my blog can be expensive. I recently switched to these centrifuge tubes instead, as they are much, much cheaper, and they should work just fine, reading the comments, but I have not tested them personally yet, so have not updated my blog. The only downside to doing slants is it does take about 7 days to get a pitchable amount of yeast, so you have to be able to prepare ahead of time.
I bought a 50 pack of these plastic Centrifuge tubes for mixing on the go. One 50 mL tube holds almost exactly a single serving of Tailwind. Plus, I can fit two full tubes in the storage pouch of my Nathan SpeedDraw plus. I used this setup for a Marathon and a few trail races and it worked great. The tubes are so cheap you can dispose of them if you want, or save and wash them for reuse. Much better than the formula dispenser option you're looking at IMO.
Edit: Here's an updated product link to what appears to be the same item, but is in stock.
They are LITERALLY THE BEST!
We had some expired ones at work (I work in clinical trial drug dev) and my boss said I could take them home :D
Edit for finding some on Amazon! woot!

Sample tubes used daily in biology labs. They definitely won't leak if capped tightly!
So I uh, cheat, and use Northern Brewer's Fast Pitch. I absolutely love this product as it means I can whip up a starter in ~5 mins before leaving for work in the morning (because inevitably that's the only time I remember I need a starter for later in the week). If you'd rather make your own starter wort, it's pretty simple - all you need is DME, and the measurement can be calculated here.
Otherwise, my method is the same as /u/pricelessbrew's above, which was originally from /u/brulosopher here. As I mentioned, I use centrifuge tubes for storing yeast - this actually was a method someone here suggested on a daily Q&A thread a few months back that I can't find now. Containers are cheap enough to only use once, and are pre-marked with volumes to be able to estimate cell count. Highly recommended.
Tuck one of these between your legs or put it up your butt/vag
The water probably does more harm than good. If you need some liquid to cover the yeast, use American light beer/Intl. pale lager.
For centrifuge tubes, /u/theJexican18 use skirted centrifuge tubes, $14 for 50 tubes.

Oh gotcha. There are a bunch of use videos and articles about yeast propagating and yeast ranching that you can watch to learn more. After I grow up the population of yeast, I divide it and refrigerate them in either 50 ml sterile centerfugale tubes or in 1 pint Mason jars depending on size. I buy the centerfugale tubes on Amazon. All in all, It's easier than it looks and is fun to experiment with. As long as you pay extra close attention to sanitation and sterilization you should be fine.

Maybe I'm misunderstanding, but couldn't you just use plastic Falcon centrifuge tubes? They would be lighter, less likely to shatter, and probably significantly cheaper.
You're welcome -- glad I could help!
If you decide to go with large tubes, these are similar to the tubes I use, but there are cheaper options: 1, 2, 3, etc. It's important to look for tubes that are listed as either "sterile" or "autoclavable." I like the pre-sterilized packs because that's less work for me.
There are a lot of techniques out there, so sometimes it helps to list them out into categories with a few details underneath each. With a list like that, you can go through it all at a glance and decide what aligns with your budget, material availability, and level of effort/interest.
Let us know what you end up deciding to do and how it works out for you. I'm sure a lot of folks around here would like to see it!
Vallejo paints are acrylics which behave differently in an airbrush than enamels. Acrylics dry much faster.
To answer your question, Vallejo model color paints are great to brush paint and airbrush. If you want to airbrush then you should add some Vallejo thinner to it. The paint is very concentrated so you won't need much.
The other pack is model air which is specially designed for airbrushing. So you won't need thinner for it. It can also brush paint fine so i have heard. (I only own model color)
You are saying that you are wasting paint because it is hard to get the paint out of the tin into the airbrush. I am assuming you just pour out of the tin, why not just buy some Pipettes and save yourself £60. I have seen packs of 100 pipettes for around £5.
In labs, we used to use tiny plastic things called transfer pipettes for this sort of thing, like these: https://www.amazon.com/uxcell-Plastic-Liquids-Pipetting-Pipette/dp/B00N3Y0BFE
They come in different sizes. https://www.amazon.com/Lab-Pipettes/b?ie=UTF8&node=318122011
I've got 14 different strains right now by my last count. Just stepped up a frozen Imperial Juice last night and I'm stepping back up a frozen Bell's House yeast as I type this.
I use these but it doesn't seem they're for sale anymore. In any case, any 50ml vial will probably work.
My normal routine is to make a 1.5L starter in a 2L flask and decant off most of the supernatant after the fermentation is complete. I try to swirl in a little just to make sure that the yeast isn't too thick and can actually pour. A semi-thick starter like this, for me, will usually fill 6-8 50ml flasks up to the 25ml mark.
Starter calculators are a wild guess at best in terms of actual cell counts, but if I can suppose that I have close to 30-40b cells per vial I'm usually okay with that amount.
For glycerin, I use a 10% mix total (20% mix into the vial). Usually 1 cup of distilled water and 1/4 cup of glycerin will be plenty for my fills. I'll take this mix and stir it together in my instant pot. I cook the mix for like 3 minutes on high pressure and then release it. I'll take the pot out of the instant pot and let it cool with the lid on.
Once my glycerin is cool and my yeast is decanted I'll fill as many 50ml vials as I an with a 50/50 mix of each slurry and glycerin. I'll label them with what the yeast is, date it, and add what generation it is. I haven't gone beyond 3rd generation, I figure if I can get something like 15-20 pitches out of a pack of yeast I can leave it at that. I'll also label the cap of the vial too so I can identify them easily when looking at them from above.
Once they're all full I stick them in the fridge for 24 hours to cool. After that I'll take them down to my freezer and shake them all up again before sticking them into a styrofoam container that I keep in my chest freezer. The styrofoam helps protect the yeast from freeze / thaw cycles.
When I want to make a starter I try to plan it a few days in advance. I prefer to thaw the yeast vials in the fridge for a day, but soaking them in a bowl of water for an hour has seemed to work just fine as well. I make a mix of .1g per ml starter wort depending on my needs (usually back up to 140g in 1400ml or so) and pitch the thawed yeast. It's usually about done in 18-24 hours! That gives me enough time to cold crash it a bit so I can pour of the supernantant for my actual pitch into my wort.
Second, though OP might prefer flat-bottom ones (https://www.amazon.com/Karter-Scientific-Centrifuge-30x115mm-Skirted/dp/B005Z4S2QU/ref=sr_1_9?s=industrial&ie=UTF8&qid=1484842696&sr=1-9&keywords=ml+conical).
Cheap 50ml tubes and a rack for them.
They aren't pressure safe like the preforms are, so make sure you're all gassed off before you seal it for long term.
I usually keep it in a jar with the lid loose for a while before I decant and move the slurry over to a tube for longer term storage.
Right now I've got only six strains, but I only recently started harvesting from starters. My go-tos tend to be:
I bought 50 of these back in 2015 and have a ton of them left. I swirl the starter and decant off enough to fill 4-6 tubes to the 45-50 ml mark. That usually gets me 15-20!ml of yeasties once it chills for a while.
These are a little different from the one you get from Anderson/Goulet/etc but it's a 50 pack.
I was able to find that it's a centrifuge vial...any lab techs have any ideas on what the contents might be?
Also found these. Complete with a rack, and a spot on the vial to write on.
I make a starter for every yeast that I buy and then save a little bit in 50ml vials. If I ever want to use a yeast that I have I just create a starter 3 days ahead of brew time. I used to use mason jars, the 1/4 pint ones (4oz I think) but found out that these take up way less space.

yeah i didn't know how to do shit when i got into mopeds. You gotta learn fam.
5,000 miles is a really long time.
Unless you are racing your bike and need 10000% consistant ass blaster performance all the time, premixing is not as delicate or required as you think it is. just dump oil in at the pump; if it's close it's good enough. get a little doodad that's metered that you can carry oil around in if you are worried.
Think of wires as tubes and the electricity as fluid.
Ignition systems are fairly simple when it comes to the wiring. Well i guess the Urban express is a hair more complicated since it's a CDi but it's still pretty simple. more straightforward than the lighting.
Find a wiring diagram.
Hell, here's a video about circumventing the majority of the ignition electrical system.
Either way, i think you are underestimating the difficulty/cost(if you can't weld and shit) of swapping the subframe with a GY6. but you do you
They make ones that stand on their own!

Had no idea what a nunc cryotube was, but after some Google/Amazon-fu, I do believe you got me on the right track! Probably looking at something like a 50mL centrifuge tube (like this one ). Guess I'm need to first determine what the volume my "single serving" is and scale up as needed.
Would it be easier to keep things separate and use single serve creamer/sweetener from the store? Yes, but I'm also trying to keep my waste by-products down and go re-usable wherever possible.
Thanks for helping me get on the right track!
Do you have stuff to make starters already?
Stir plate, flask (get two), dme. Pick up some plastic 50mL tubes, and start doing some starter harvesting to keep a few strains on hand that you like.
Fermentation temp control is something you really want to take care of. It's usually said that it's the #1 thing to improve your beer (along with starters). If nothing else, make a swamp cooler or a son of fermentation chamber out of a box or rubbermaid bin.
Yea I ended up buying those lil centrifuge test tubes some breeders ship in now. Fill with seeds, some rice, good to go!
I got two packs of Omega yeast (OYL-500 & OYL-052) for free from my LHBS as they were packaged in January. How can I recover and store these? I was thinking a two stage yeast starter on my stir plate, cold crashing and pitching the slurry into one of these, then storing in the fridge. If I do that, how long will they last? And would it be a good idea to pitch them in another starter before use?

These work great.
You need to make some slants. Petris in the fridge dry up and end up with water matted on the surface.
check these out . I haven’t used they yet, and make sure you get a tray so you can PC them. I’ve used the glass ones, but those are really expensive.
Have you looked into something like these?
Do you need these specific tubes? If not, search "centrifuge tubes" on amazon. There are a wide variety of sizes 5mL and up.
