Burets are the main measuring instruments used in titrimetric analysis, which can be divided into two types: acid burets and basic burets.

The burette with the latex tube containing glass beads at the lower end is called the basic burette, which is commonly used to measure the volume of non oxidizing dilute solution, mainly measuring the volume of alkaline dilute solution. Acids with oxidizing and erosive latex tubes cannot use the basic burette.
