Abstract

La présente invention concerne un dispositif de dosage d'échantillons, destiné à des systèmes d'analyse. Une conception ciblée du système de canalisation du liquide et le déplacement du liquide d'une partie donnée du système de canalisation du liquide permettent le dosage de volumes définis compris entre 0,01 νl et 100 νl. Le dispositif de l'invention convient particulièrement à l'analyse ultérieure de l'échantillon par isotachophorèse.
