INSTRUCTIONS FOR USE OF MICRO BURETTE (Fig. 2-4).
The micro
burette consists of a graduated barrel (2) with a tipped plunger (1)
that slides freely back and forth inside the barrel.
The standard
micro burette has twenty major (numbered) divisions (3) and each major
division is divided into five subdivisions.
All readings are made
where the bottom of the plunger tip (4) intersects the graduated
scale.
Special dispenser flasks (5) and titration vials are used.
These flasks include stoppers (6) into which the tip of the micro
burette is inserted.
To prevent leaking a tight fit is required, and
the first use may require some pressure when inserting the burette tip
into the fitting.
