How It Is Used
The burette is filled with titrant and the PTFE stopcock is opened to add it a little at a time to the solution being titrated, and the volume delivered is read from the burette. Because the body is acrylic, it should not be used with hydrofluoric acid or ammonium hydroxide.
Frequently Asked Questions
Which chemicals should not be used in the Burette?
Hydrofluoric acid and ammonium hydroxide. Otherwise the acrylic body is unaffected by dilute mineral acids and bases within pH 1–14, up to 5% wt/wt acids or 30% bases.
