LIQUID DISTRIBUTION AND METERING |
摘要 |
Devices for handling liquid, for example microfluidic devices, are described, which are rotatable about an axis of rotation to drive liquid flow within the device. The 5 devices provide one or more of an aliquoting structure (6) having a plurality of daisy chained aliquoting chambers (100, 200, 300) for providing a plurality of aliquots, arrangements for sequencing the dispensing of the aliquots by controlling the rotation of the device and arrangements for ensuring that a fault condition can be detected when insufficient liquid is present in the device to fill 10 all aliquots. Further disclosed are arrangements for ensuring a detection chamber (12) of the device remains filled with liquid, arrangements for reducing the risk of air ingress to the detection chamber (12) on repeated emptying and filling of a supply structure (10) and arrangements for reducing the risk of bubble formation when filling the detection chamber (12). A corresponding system for operating the 15 device and method for processing of a sample using the device is also disclosed. |
