Abstract
A centrifuge unit for a microfluidic device for processing liquid samples includes a centrifuge cup and at least one centripetal force-dependent valve function.
Claims15
A microfluidic device for processing of liquid samples, comprising:
- at least one centrifuge unit comprising:
- a centrifuge cup;
- and
- at least one centripetal force-dependent valve arrangement,
- wherein the at least one centrifuge cup is mounted rotatably between two layers of the microfluidic device.
2 more elements
A method for operating a microfluidic device with a centrifuge unit having (i) a centrifuge cup that is mounted rotatably between two layers of the microfluidic device and (ii) at least one centripetal force-dependent valve arrangement, the method comprising:
- after introduction of the sample into the centrifuge cup, rotating the centrifuge cup between the two layers at a first speed in a first phase and rotating the centrifuge cup between the two layers at a second, increased speed in a subsequent second phase, wherein the increased speed causes actuation of the at least one centripetal force-dependent valve arrangement of the centrifuge unit.
