    MacGyver would approve of that one. I didn't realize you could take them apart.

You'll need one long enough and thin enough to get accurately to 10 mL and it might be a pain to refill as you'll need the top of the liquid visible.
    I could just get a giant 100ml column, couldn't I? And titrate 10ml at time?

    (Still not as easy a pushing a button...)

    But possible, right?

    I would guess that they are 100 mL. I haven't used one in 20 years but they are usually 1 cm across so 100 mL would make them a meter long (sounds right). I wouldn't go any bigger as it'll be too clumsy to read with any accuracy (even 10 mL). They are just a glass tube with a tap at the end. You could go to a local glass blower and have one made for really cheap and put whichever stop tap system you like on it. If you did 2 cm diameter, you'd just make a load of 5 cm marks on it, perhaps you could get a 200 mL one and do 10 fills, make it 100 cm long, per fill of the column?

    Get a glass blower to put a push button stop on the end of a glass column. $10 job from a local university with a glass blower. Or go really simple, get a glass tube and fit a rubber tube to teh bottom that you can squeeze as an off and on. Manually mark the 10 mL on the column.

    How about a hand pump that dispenses the exact about you need with each cycle?https://www.uline.com/BL_8162/Plastic-Pail-Drum-Pump

    In woking with various two part epoxies and resins that need to be measured precisely in order to kick off correctly I have found these to be very handy.
    Just because you won't listen to reason does not mean I have to listen to idiocy.

    That is a good idea. I would just need to find a miniature one.

    Add a manifold at the business end, and you could multiply the number of containers you fill per shot, say 5-10 at a time.

    Mark your measured quantity on one container. Fill 200-500 identical containers to the top and let evaporation do its thing until your measured container hits you mark. #lazycheap

    How about a rubber hose and two clamps attached to the larger container? space the two clamps so they are 10mL apart. Open top clamp to load and bottom clamp to fill.

    I think I am going to be best off with a pump that will allow me to just pump out a measured amount...whether I adapt a lotion dispenser or find a very very small pail type pump. Thanks for your help. I knew you guys would come up with some good options.

    Not really, but tediously pouring something so small and watching the scale is going to take too long and have more room for error, knocking over a bottle, etc. A one-pump shot or dose is going to be easier / faster if I can do it.

    how much can you put in your mouth? Just spit it out into the container!
    Of course I'm sure...that doesn't mean I'm right.....
