Abstract

Dispositivo para la toma de muestras líquidas para elementos analíticos, en el que se transporta la muestra en un canal capilarmente activo (3) desde el lugar de toma de muestras hasta el lugar de destino y en el que el canal capilarmente activo (3) está formado sustancialmente por un soporte (1), una cubierta (7) y eventualmente una capa intermedia (9) situada entre la cubierta (7) y el soporte (1), caracterizado porque en una superficie que forma el canal (3) capacitado para el transporte capilar de líquido se encuentra, contra la superficie lateral del dispositivo que contiene la abertura (4) de carga de muestras, una escotadura (5) en forma de una incisión parcial, comenzando la incisión en la superficie lateral del dispositivo y mirando desde el lugar de toma de muestras en la dirección del canal capilarmente activo (3), de modo que queda al descubierto la superficie opuesta a la escotadura (5).
