Les burettes d\u2019origine DURAN\u2122 sont en verre borosilicat\u00e9 3.3 hautement r\u00e9sistant aux produits chimiques. Leur mise \u00e0 l\u2019\u00e9chelle pr\u00e9cise les rend particuli\u00e8rement adapt\u00e9es \u00e0 la titrim\u00e9trie. La quantit\u00e9 de liquide requise pour la titration, pr\u00e9c\u00e9demment inconnue, peut \u00eatre lue tr\u00e8s pr\u00e9cis\u00e9ment \u00e0 la fin de la r\u00e9action. Le r\u00e9glage consiste \u00e0 vidanger (Ex) pour atteindre la temp\u00e9rature de r\u00e9f\u00e9rence + 20\u00b0C. Cela signifie que les quantit\u00e9s peuvent \u00eatre prises exactement en fonction de l\u2019\u00e9chelle, puisque l\u2019adh\u00e9rence du liquide au verre a \u00e9t\u00e9 prise en compte lors de l\u2019\u00e9talonnage. Les tol\u00e9rances pour le volume correspondent aux limites d\u2019erreur d\u00e9finies par les normes ISO et DIN. Les burettes DURAN\u2122 sont disponibles avec des cl\u00e9s en verre ou en PTFE. Contrairement aux cl\u00e9s en verre, la lubrification des cl\u00e9s en PTFE est inutile, ce qui simplifie le travail en laboratoire. <\/p>\n
