verre neutre<\/h2>\n

LBG N est un verre borosilicat\u00e9 neutre \u00e0 haute r\u00e9sistance chimique. Son coefficient de dilatation
lin\u00e9aire moyenne est 8,0\u202210-6 K-1. Il est utilis\u00e9 dans des produits qui ne sont pas destin\u00e9s \u00e0 \u00eatre chauff\u00e9s directement mais qui doivent avoir une grande r\u00e9sistance m\u00e9canique (mortiers, dessiccateurs, fioles Kitasatos...) et certains mat\u00e9riaux volum\u00e9triques (par exemple pipettes, burettes...).<\/p>\n

verre borosilicate<\/h2>\n

LBG 3.3 est un verre borosilicat\u00e9 ayant une teneur minimale en silice de 80% et un tr\u00e8s faible coefficient d\u2019expansion (3,3\u202210-6 K-1) qui appartient au groupe des borosilicates de type \"3.3\" tels que d\u00e9finis dans la norme ISO 3585. Il est utilis\u00e9 dans les produits o\u00f9 la r\u00e9sistance chimique, la r\u00e9sistance m\u00e9canique et la r\u00e9sistance aux changements brusques de temp\u00e9rature doivent \u00eatre combin\u00e9s, et c\u2019est pour cette combinaison unique de propri\u00e9t\u00e9s que la plupart des produits de laboratoire sont fabriqu\u00e9s.
