its used to measure exact drops of liquid...used them a lot in biology labs...I cant recall the name of it... micrometer?

any chemisty or biology majors here to help?!

I remember using burettes to do that with and I think maybe those graduated cylinders did it too.

just sell your acid in bult so you can use a measuring cup

i think you are thinking of a pipette

okay just read your question again
either a pipet (to extract specific amounts of liquid from a sample)

or a buret to dispense specific amounts of reagents

Back in the day when I worked in a high performance machine shop i would cc cylinder heads with a burette.

I'd level the head, put a thin coat of Vaseline on the gasket surface and place a big piece of Plexiglas over the entire head. The Plexiglas had a small hole centered over each chamber and I would fill each one with that green rubbing alcohol out of a burette measuring each combustion chambers volume.

The trick was to have them all equal within so many cc's depending on the size of the chamber. Smaller chambers it was more critical to have less variance between them. To change the volumes you had to grind valves and valve seats down a little to make the chamber larger working the smaller ones up to the largest.

Afterwards you could angle mill the head taking more meat off the deepest part of the chamber to make them all smaller at the same time.

This was back in the late 80's, and back then I was working on $50,000.00 blown big block Chevys. All I did all day was work on cylinder heads and the burette was a tool I used daily. I miss it a lot but had to move on.
