I have to sample $\pu{10mL}$ of liquid hundreds of times a day at work.

We use a $\pu{10mL}$ syringe to do so, but it takes a lot of time as they often allow more than $\pu{10mL}$ to be drawn in (i.e. rather than a blind action, we have to check the measurement increments to make sure it’s exactly $\pu{10mL}$).

Is there a type of syringe of other piece of equipment designed to draw in exactly $\pu{10mL}$ (or other amounts) of liquid?

If you need to measure $\pu{10.0\pm0.1 mL}$ repititively, then you can use an any available Bottletop Dispensers. For example, check this and this out (see image below):

Bottle-top Dispensers

If you are in a educational facility, Fisher would offer attractive discount (request a quote from fisher representative in your area. For example, I got $\pu{1.0-10.0 mL}$ dispensers for less than $100/each in that way (I bought 15 of them though). Still, it is a good price.

    $\begingroup$ I don't know why, but I find these so satisfying to use! $\endgroup$ – orthocresol Jan 17 at 0:48
  • $\begingroup$ Yep, they are very convenient. I use them in undergraduate organic chemistry labs so students do not waste solvents using grad cylinders any more. Save time as well. :-) $\endgroup$ – Mathew Mahindaratne Jan 17 at 0:54

    $\begingroup$ I only remember getting to use them once when I was an undergrad - it was used for CDCl3, to measure out ca. 0.5 ml of solvent to make up an NMR sample. I guess it only really makes sense if you have a repetitive task (and a chemical that's reasonably harmless, of course). $\endgroup$ – orthocresol Jan 17 at 1:01

    $\begingroup$ This could be a great solution if the OP needs to repeatedly dispense 10 mL of liquid; but it's possible he instead needs to repeatedly sample 10 mL of liquid (e.g., for some sort of production line QC). That's why I asked him to explain what he needs it for. $\endgroup$ – theorist Jan 17 at 2:22

    $\begingroup$ And, OP is using a syringe. Accuracy of this is compatible with syringes and a way fast. $\endgroup$ – Mathew Mahindaratne Jan 17 at 3:59
