Fluidic System For The Rotational Cycle-Determined Release Of Liquid From A Chamber In A Rotor

Abstract:

See patent information below. The present invention relates to a fluidic device. More specifically but not exclusively, the present invention relates to serial siphon valves for a fluidic device.

Control of the release of liquid from a fluidic chamber via a spinning rotor is a very important function in the area of centrifuged-based fluidic systems for applications such as immunoassays, nucleic acid analysis, biochemical tests, chemical tests, and sample preparation. This is because it is often necessary to mix different reagents together at the appropriate time, either in parallel or in series.

It is a non-limiting object of the present invention to provide a method using a co-radial arrangement of siphon structures each separated by a capillary valve in a fluidic system. Such a method allows for saving radial space. This saved radial space can be used, for example, to add more features to a fluidic device.

It is a non-limiting object of the present invention to provide siphon structures that enable to sequentially distribution of liquids in a fluidic system upon successive centripetal accelerations and decelerations applied to a rotary platform. Sequential fluid distribution can be controlled by the length and number of serial siphon structures.
