INTERFACING AN INLET TO A CAPILLARY CHANNEL OF A MICROFLUIDIC SYSTEM

The invention relates to microfluidic systems, and more specifically to a microfluidic system comprising a capillary channel (14) and an inlet (12) for receiving a fluid, as well as a method of filling a capillary channel (14). Provided is a microfluidic system, having an inlet (12) for receiving a...

Zusammenfassung:The invention relates to microfluidic systems, and more specifically to a microfluidic system comprising a capillary channel (14) and an inlet (12) for receiving a fluid, as well as a method of filling a capillary channel (14). Provided is a microfluidic system, having an inlet (12) for receiving a fluid, a capillary channel (14), an outlet (20) for letting excess fluid out, and a reservoir (10) for interfacing the inlet (12) to the capillary channel (14). The reservoir (10) forms a first passage from the inlet (12) to the outlet (20), and a second passage from the inlet (12) to an entrance (22) of the capillary channel (14). A hydraulic resistance of the first passage is sufficiently low in order to effect a pressure reduction at the entrance (22) of the capillary channel (14) when a fluid is received under pressure at the inlet (12).
