Laboratory Glassware Borosilicate Glass Burette PTFE Burette with Different Size

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.

The calibration of the buret is the same as that of the volumetric flask. The water weighing method is used, that is, according to the different densities of pure water at different temperatures, the water quality at different scales of the buret is measured according to V=m/ ρ， Calculate the volume of pure water at a new temperature, which is the real volume of the buret at the new scale.
