MICROFLUIDIC VALVE HAVING IMPROVED TOLERANCE TO PARTICLES

摘要

The present invention describes a valve for controlling the passage of a microfluidic system. Said valve comprises a first valve element (103) and a second valve element (104, 105) with respective first and second contact surfaces which are placed opposite to each other in such a way as to control a fluid flow through said passage. Said first valve element comprising a flexible part and a rigid part.

主权项

1. A valve for controlling the passage of a microfluidic system, said valve comprising a first valve element and a second valve element, having respectively a first surface and a second surface which are placed opposite to each other and are designed to come in contact in such a way as to control a fluid flow through said passage;characterized by the fact that:
the first valve element comprises a planar component which is composed of a rigid part and a flexible part which are not in contact with the second valve element when the valve is open; the first surface is composed of the surface of the rigid part and the surface of the flexible part; the second surface is adapted to be in contact with the surface of the rigid part and the surface of the flexible part when the valve is closed; the rigid part and the flexible part are made from a same material.
