Burettes
Burettes
Used to dispense and measure a variable amount of a chemical solution in analytical chemistry at the same time, burettes feature a long, graduated glass tube with a stopcock on its lower end for liquid measurement. The stopcock valve is used to control the flow of liquid from the burette in either a steady stream or drop-by-drop. Unlike a pipette, the sample quantity delivered by a burette is changeable. For gas measuring burettes, the stopcock is located at the top of the burette’s glass tube. Digital burettes that deliver exactly measured samples, increasing accuracy and precision, are also available.
