Abstract

ESTAS MEMBRANAS POROSAS LAMINADAS HIDROFILICAS SON UTILES EN LOS DISPOSITIVOS DE ENSAYO CROMATOGRAFICO E INCLUYEN MEMBRANAS DE NITROCELULOSA O DIFLUORURO DE VINILIDENO (PVDF) LAMINADAS EN SOPORTES. A PESAR DE LA LAMINACION, LAS MEMBRANAS PERMANECEN HUMEDECIBLES Y NO SE PERJUDICA LA ACTIVIDAD DE LOS REACTIVOS BIOLOGICOS DEBIDO AL USO DE ADHESIVOS BASADOS EN AGUA AL FABRICAR LAMINADOS. LOS ADHESIVOS BASADOS EN AGUA INCLUYEN AS73 DE POLIVINILACETATO (PVA) Y POLIVINILPIRROLIDONA (PVP) DE ADHESIVE RESEARCH INC. ENTRE OTROS.
