If a calculator like Bru'n Water says I need to a liquid substance like acid, what's the best technique for measuring out and dispensing the liquid, especially in fractional small amounts (eg 1.3 ml)?
Medicine syringes given for free with kids antibiotics are great for very small amounts and measure in milliliters.
The best? A pipetting robot. But the graduated plastic syringes as mentioned above will likely do OK.
High School and College Chemistry classes are a long way in the rearview mirror now. Any issues with the acids commonly used for water adjustment adversely interacting with plastic syringes?

Yeah in hindsight I probably used the wrong choice of words. "Most practical" would be a better term. Cheap but effective would be another.

I probably do most dispensations of acid with Hach TenSette pipets. One is adjustable from .1 to 1 mL and the other from 1 - 10 ml. For quantities less than that I use an Eppendorf adjustable pipetter. These all use disposable tips but they are very handy.
Lactic acid comes in a plastic bottle. If it lactic acid did anything to plastic, there would be a lot of empty bottles with lactic acid dripping out.
