Burettes
En chimie analytique et quantitave, les burettes sont utilisées pour mesurer les solutions liquides et les gazs. Contrairement aux pipettes, étant donné la fluctuation des quantités d'échantillons, les burettes sont principalement utilisées dans les expériences de titrages. Le robinet d'arrêt se situe à la fin du tube verticale sur les modèles destinés à la mesure de liquides, alors qu'il se situe au sommet du tube sur les modèles destinés à la mesure de gazs. Pour une précision sans faille, Avantor recommande ses burettes numériques.
