If I'm remembering correctly a burette is used for titrations, it is 
basically a long narrow (glass) tube with precise graduations etched 
in its side and a stopcock at the bottom.  It allows precise 
measurements of how much of a chemical has been added to a solution.

To be honest I don't use one, I use cheap plastic syringes.  Not as 
precise, but then I only want to know approximately my total Acidity.

I believe Presque Isle Winery (which sells wine-making supplies via 
catalog), sells burettes, but they don't list them online, you'd have 
to send for their paper catalog:  http://www.piwine.com
There may be cheaper sources.
