VIDRO NEUTRAL<\/h2>\n

LBG N \u00e9 um vidro borossilicato neutro com alta resist\u00eancia qu\u00edmica. O seu coeficiente de expans\u00e3o
a m\u00e9dia linear \u00e9 de 8,0-10-6 K-1. \u00c9 utilizado em produtos que n\u00e3o se destinam a ser aquecidos directamente mas que devem ter uma elevada resist\u00eancia mec\u00e2nica (argamassas, dessecadores, frascos de Kitasate...) e em alguns materiais volum\u00e9tricos (por exemplo, pipetas, buretas...).<\/p>\n

VIDRO DE BOROSSILICATO<\/h2>\n

LBG 3.3 \u00e9 um vidro borosilicato com um teor m\u00ednimo de s\u00edlica de 80% e um coeficiente de expans\u00e3o muito baixo (3,3-10-6 K-1) que pertence ao grupo dos borosilicatos \"3,3\" tal como definido na norma ISO 3585. \u00c9 utilizado em produtos onde a resist\u00eancia qu\u00edmica, a resist\u00eancia mec\u00e2nica e a resist\u00eancia a mudan\u00e7as bruscas de temperatura devem ser combinadas, e devido a esta combina\u00e7\u00e3o \u00fanica de propriedades, \u00e9 o tipo de vidro de refer\u00eancia a partir do qual a maioria dos produtos de laborat\u00f3rio s\u00e3o fabricados.
