20140109972 | CONTROL OF LIQUID FLOW SEQUENCE ON MICROFLUIDIC DEVICE - Described embodiments provide devices, systems and methods for sequencing liquid flow in response to a driving force by entrapping and releasing gas between volumes of liquid in a controlled manner. In one particular form, a centrifugal “lab on a disk” device is provided to drive liquid flow and sequencing by virtue of the centrifugal force and in one particular form a radially inward bend conduit is used in connection with controllably trapping and releasing gas between liquid volumes. | 04-24-2014 |
20140087934 | LIQUID SWITCHING, DOSING AND PUMPING - A liquid handling device having an upstream liquid handling structure connected to a downstream liquid handling structure by a conduit. The upstream and downstream liquid handling structures are sealed or sealable such that the conduit provides the only fluidic communication paths between the upstream and downstream liquid handling structure. The device is arranged such that a driving force causes liquid in the upstream liquid handling structure to at least partially fill the conduit to separate gas in the upstream liquid handling structure from gas in the downstream liquid handling structure. With the device set up such that the two gas volumes are separated by a liquid volume, gas pressures and liquid flow in the device can be controlled by control of the driving force. The device may be arranged for rotation about an axis of rotation to provide the driving force. | 03-27-2014 |
20140087479 | LIQUID REAGENT STORAGE AND OPERATION OF ANALYTICAL DEVICES - Improved mechanisms for storing and introducing liquid volumes in a liquid handling device and, in particular, improved mechanisms for rupturing a liquid storage package to introduce liquid into the device, improvements to the stability of a liquid receiving chamber inside the device and improvements to liquid handling in the receiving chamber are achieved. | 03-27-2014 |
20130074962 | LIQUID DISTRIBUTION AND METERING - 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 ( | 03-28-2013 |
20130027688 | SURFACE PLASMON RESONANCE DETECTION SYSTEM - A system for detecting the presence of an analyte in a moving substrate or sample handling device is disclosed, providing means ( | 01-31-2013 |
20120021447 | ANALYTICAL ROTORS AND METHODS FOR ANALYSIS OF BIOLOGICAL FLUIDS - Devices for generating discrete flow of liquids in response to a driving force, for example centrifugal microfluidic devices for generating discrete flow in response to a constant driving force. The device includes a supply structure for supplying liquid at an inflow rate to a discretization structure in response to a driving force. The discretization structure is shaped to define an outlet and a level to which the discretization structure fills with liquid flowing from the supply structure before dispensing the liquid at an outflow rate through the outlet in response to the driving force. The device is arranged such that the outflow rate from the discretization structure is greater than the inflow rate into the discretization structure, thereby periodically emptying the discretization structure to create a discretized flow from the outlet. The devices find applications in liquid mixing, for example for diluting samples, such as blood plasma samples. | 01-26-2012 |
20110290718 | JET DEFLECTION DEVICE - Devices for controlling fluid flow, in particular microfluidic devices, are described, which exploit gas/liquid interfaces to control liquid flow in accordance with application requirements. Devices for on/off flow switching, centrifugal separation, mixing, metering and aliquoting are described. | 12-01-2011 |
