Abstract
Dispositivo para el transporte capilar de un líquido entre dos capas opuestas sustancialmente planares, en donde las dos capas están dispuestas paralelas una a otra a una distancia tal que existe una rendija capilarmente activa (6) entre ambas capas, caracterizado porque al menos una de las dos capas contiene al menos dos partes discretas yuxtapuestas (2, 3), estando aplicada sobre el lado - vuelto hacia el canal capacitado para el transporte capilar de líquido - de una parte de la capa que consiste en al menos dos partes una lámina flexible inerte (7) de un espesor de menos de 5 ìm, la cual se extiende por toda la longitud de la parte citada, cubre el canal capilar en toda la anchura y cubre parcialmente la parte contigua de la capa en el lado vuelto hacia el canal capacitado para el transporte capilar de líquido.
