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.
