Abstract

Un dispositivo que comprende una plataforma y una o más membranas porosas secas (11, 20) para detectar al menos un componente en una muestra líquida de volumen bajo, proporcionando las membranas un canal de membrana a través del cual la muestra líquida puede fluir por capilaridad al tiempo que tienen lugar reacciones determinativas de al menos un componente en la muestra; la plataforma formada con el medio de aplicación de la muestra y que tiene capas superiores (1) e inferiores (5) con superficies hidrófilas para encerrar y colocar las membranas, teniendo cada capa una superficie de la capa superior e inferior formada de modo que la superficie inferior de la capa superior y la superficie superior (10) de la capa inferior (5) puede fijarse en contacto cara a cara para que las capas encierren y sujeten las membranas en su lugar; caracterizado por que un canal para flujo de la plataforma se forma aguas arribas de las membranas e incluye una indentación en al menos una de las superficies hidrófilas, estando el canal formado en comunicación con el borde de las membranas para permitir que la muestra líquida fluya en una vía continua desde el medio de aplicación de la muestra hasta el extremo distal de las membranas.
