Abstract

EN LA REALIZACION DE CENTRIFUGACION CON GRADIENTE DE DENSIDAD EN MEZCLAS DESPUES DE LA CENTRIFUGACION SE HA PREVISTO LA COLOCACION DE UN SALIENTE AJUSTADO MEDIANTE INSERCION EN CAPAS EN EL INTERIOR DEL RECIPIENTE. LA PARTE INSERTADA ES CAPAZ DE SOPORTAR EL CUERPO DEL LIQUIDO EN DISPERSION PARA SER CENTRIFUGADO BAJO LAS CONDICIONES DE GRAVEDAD REGULAR Y PERMITE EL CRUCE DE FLUJO BIDIRECCIONAL DURANTE LA CENTRIFUGACION. UNA PLACA PEQUEÑA CON MASA DE FILTRO PUEDE SER COLOCADA EN LA PARTE SUPERIOR DE LA PIEZA INSERTADA EN FORMA DE CAPAS.
