Abstract
METODO PARA CONCENTRAR UNA SOLUCION DE ANTIBIOTICO DE ~J-LACTAMA POR MEDIO DE UNA MEMBRANA PERMEABLE. CONSISTE EN SOMETER UNA SOLUCION ACUOSA DILUIDA DE UN ANTIBIOTICO DE ~J-LACTAMA, CONTENIENDO DICHA SOLUCION DE UN 2 A 20% EN VOLUMEN DE UN ALCOHOL INFERIOR, A CONCENTRACION, EMPLEANDO PARA ELLO UNA MEMBRANA PERMEABLE HECHA DE POLI(ETER/AMIDA) O POLIBENCIMIDAZOLONA, A TEMPERATURA AMBIENTE. DICHA MEMBRANA PERMEABLE SE PREPARA DEPOSITANDO UNA CAPA DELGADA DE UNA SOLUCION ACUOSA DE UN CONDENSADO DE EPICLORHIDRINA-ETILENDIAMINA SOBRE LA SUPERFICIE POROSA DE UNA MEMBRANA DE SOPORTE DE POLISULFONA.
