Abstract

A burette has a main tube made of precision bore tubing and a piston which is a close fit in the main tube and which can freely slide through the main tube while riding on the liquid column below it within the main tube. The specific gravity of the piston is preferably close to that of water so that when as is usual, dilute aqueous solutions are being used in the burette, the piston rides on the liquid column below it with very little or no tendency to sink and a reference mark in the form of a line or edge to the flat surface on the piston. The piston may have a series of marks equi-spaced longitudinally along the curved surface of the piston to make a vernier scale for the linear scale provided for the main tube.
