Laboratory Glass Burette Borosilicate Glass Burette PTFE Burette with Different Size

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.
