摘要： Devices and methods for handling liquids are provided. The devices and methods make use of specifically controlled centrifugal forces to drive liquid flow between two cavities connected by a conduit such that as liquid flows into the second cavity, a gas volume is trapped in the second cavity and a pressure of the gas increases, allowing for pneumatic control of liquid flow. The devices and methods facilitate one or more of the mixing, metering and sequencing of liquids, for example on a microfluidic device.

摘要： A device is disclosed for centrifugally driving liquid flow to sequentially dispense aliquots from a reservoir while the device rotates. Also disclosed is a method and system for analyzing a liquid to derive an indicator of sedimentation rate of the liquid using sequential aliquoting, using the disclosed device in some embodiments. A particular application is the analysis of blood samples, including sedimentation rate and hematocrit.

摘要： A holder for a pipette having a bulb is disclosed. In use, the bulb of the pipette is inserted into the holder and the user can hold the holder rather than the bulb to use the pipette. In this way, the holder enables the pipette to be held without any application of force from the user directly on the bulb. This enables the user to accurately draw a desired amount of liquid into the pipette. The holder comprises an aperture through which the bulb is accessible. The user can dispense liquid from the pipette by actuating the bulb through the aperture.
