VETRO NEUTRO<\/h2>\n

LBG N \u00e8 un vetro borosilicato neutro ad alta resistenza chimica. Il suo coefficiente di espansione
La media lineare \u00e8 di 8,0-10-6 K-1. Viene utilizzato in prodotti che non sono destinati a essere riscaldati direttamente ma che devono avere un'elevata resistenza meccanica (mortai, essiccatori, matracci Kitasate...) e in alcuni materiali volumetrici (ad es. pipette, burette...).<\/p>\n

VETRO BOROSILICATO<\/h2>\n

LBG 3.3 \u00e8 un vetro borosilicato con un contenuto minimo di silice di 80% e un coefficiente di dilatazione molto basso (3,3-10-6 K-1) che appartiene al gruppo dei borosilicati \"3.3\" come definito nella norma ISO 3585. Viene utilizzato nei prodotti in cui \u00e8 necessario combinare resistenza chimica, resistenza meccanica e resistenza agli sbalzi di temperatura e, grazie a questa combinazione unica di propriet\u00e0, \u00e8 il tipo di vetro di riferimento con cui viene realizzata la maggior parte dei prodotti da laboratorio.
