    • The present invention relates to a device comprising a capillary valve for controlling the flow of a liquid. The device comprises a compartment for containing the liquid, and a conduit for conveying the liquid from the compartment. The conduit is enclosed by first and second layers disposed in a parallel fashion. The first layer has a first surface facing towards the second layer, and the second layer has a second surface facing towards the first layer. A recess is extending from the first surface into the first layer. The first surface comprises a first surface area located between the compartment and the recess, and the recess comprises an inner surface area located on an inner surface of the recess that is closest to the compartment. The first surface area has a higher hydrophilicity than the inner surface area. Such a device can be used as hydrophobic valve in a microfluidic device. It can be manufactured in a cost-effective way, and it can be used in combination with a large variety of different liquids showing improved retaining performance.
    • 本发明涉及一种包括用于控制液体流动的毛细阀的装置。 该装置包括用于容纳液体的隔室和用于从隔室输送液体的导管。 导管由以平行方式设置的第一和第二层包围。 第一层具有朝向第二层的第一表面,并且第二层具有面向第一层的第二表面。 凹部从第一表面延伸到第一层。 第一表面包括位于隔室和凹部之间的第一表面区域,并且凹部包括位于最靠近隔间的凹部的内表面上的内表面区域。 第一表面积的亲水性比内表面积高。 这种装置可以用作微流体装置中的疏水阀。 它可以以成本有效的方式制造,并且可以与显示改善的保持性能的各种各样的不同液体组合使用。
