A fixed-volume instrument used with a pipette filler to transfer an accurate volume of solution.
Revise: Quantitative Analysis: Acid-Base TitrationsA volumetric pipette and pipette filler transfer a fixed, accurate volume of one solution into a conical flask. A burette, held vertically by a clamp and stand, delivers a measured volume of the other solution. Its tap allows the solution to be added dropwise near the end point.
An instrument calibrated to transfer one fixed volume of liquid accurately.
Name the apparatus and explain why it suits the measurement: a volumetric pipette measures a fixed volume accurately; a burette measures a variable volume accurately.
