Buretta
Le burette sono dispositivi comunemente utilizzati nella chimica analitica e quantitativa per misurare soluzioni liquide o gas. A differenza di una pipetta, la quantità di campione erogata è variabile, e le burette graduate sono ampiamente impiegate negli esperimenti di titolazione. Nelle misurazioni del liquido al fondo del menisco, il rubinetto che impedisce le perdite è situato nella parte inferiore del tubo di vetro verticale, mentre nei modelli per gas si trova nella parte superiore. Per le letture più precise sono disponibili opzioni digitali.

The DURAN® burettes are made of highly chemically resistant borosilicate glass 3.3. Their precise scaling makes them particularly suitable for titrimetric purposes. The amount of liquid required for titration, but previously unknown, can be read off very accurately after the reaction has been completed.
