  • Patent number: 8383061
    Abstract: Fluid-based no-moving part logic devices are constructed from complex sequences of micro- and nanofluidic channels, on-demand bubble/droplet modulators and generators for programming the devices, and micro- and nanofluidic droplet/bubble memory elements for storage and retrieval of biological or chemical elements. The input sequence of bubbles/droplets encodes information, with the output being another sequence of bubbles/droplets or on-chip chemical synthesis. For performing a set of reactions/tasks or process control, the modulators can be used to program the device by producing a precisely timed sequence of bubbles/droplets, resulting in a cascade of logic operations within the micro- or nanofluidic channel sequence, utilizing the generated droplets/bubbles as a control. The devices are based on the principle of minimum energy interfaces formed between the two fluid phases enclosed inside precise channel geometries.

    Abstract: A structure for holding sample-containing receptacles includes a cover with holes formed therein through which the receptacles can be accessed with a substance transfer mechanism, such as a robotic pipettor. When the transfer mechanism is inserted into and then withdrawn from a receptacle, a string of viscous material may be suspended from the mechanism. A viscous string removal element adjacent each opening engages the string of viscous material and dislodges the string from the mechanism when the mechanism moves in a prescribed path with respect to the removal element.

An automatic analyzer can set hold and discard conditions and manage the elapsed time after a diluted sample is pipetted. It is possible to check, before measurement is performed, whether or not each requested measurement item can be measured, and the length of time it takes before measurement of all samples is completed. The automatic analyzer has functions of: setting diluted sample hold and discard conditions; allowing an operator to specify a kind of sample, for example, to select between a parent sample and a diluted sample; separately executing pipetting or measurement; and displaying each requested measurement item for which a sample or a reagent is insufficient, and displaying the length of time it takes until measurement of all samples is completed.

  • Patent number: 8287806
    Abstract: A pipetting apparatus has a fluidic space to which a pressure transducer with a pressure sensor is attached with a gas filled space. The fluidic space is defined by a pipette tip, a first tubing that connects the pipette tip to a pump, and an active part of the pump. The pipetting apparatus further has an impulse generating mechanism that is in operative contact with a column of system liquid inside the fluidic space. The impulse generating mechanism induces a vertical movement in the system liquid column, which results in a pressure variation in the gas filled space that is pneumatically connected with the fluidic space. This pressure variation, as recorded with the pressure transducer and as processed by a first data processing unit during utilization of this pipetting apparatus, is taken as an indicator for the detection of penetration or of quitting of a surface of a liquid, with an orifice of the pipette tip, of which liquid an amount is to be aspirated and dispensed.

  • Patent number: 8256645
    Abstract: A fluid dispenser is disclosed where a backoff distance is determined and implemented to prevent leakage while dispensing sequentially an accurate, precise amount of fluid substantially independent of the fluid remaining in a syringe-type dispenser. The fluid characteristics of the fluid, e.g. viscosity, surface tension, etc. affect the backoff distance that may be determined heuristically for fluid type, amount of fluid remaining in the syringe and amount to be dispensed. Once the fluid characteristics are known, the dispensing may be accomplished automatically with a processor loading new drive and backoff steps to a motor controller.

  • Publication number: 20120214156
    Abstract: A diagnostic device is provided that includes a plurality of retainment regions, with the retainment regions that are separated by at least one dissolvable barrier. The retainment regions can be interconnected through at least one fluid processing passageway. A retainment region can include a container such as a retainment region, well, chamber, or other receptacle, or a retainment region such as a surface on which the material is retained. The retainment regions can include a reaction retainment region, one or more reagent retainment regions, each containing unreacted reagents, and a sample retainment region. A pressure-actuated valve can be positioned in each fluid processing passageway interconnecting the one or more reagent retainment regions with the respective intermediate retainment regions interposed between each of the one or more reagent retainment regions and the reaction retainment region. The dissolvable barrier can be a fluid flow modulator in the at least one fluid processing passageway.

  • Patent number: 8236257
    Abstract: This invention provides a biological component-measuring device, enabling the operator to easily calibrate the entire device and capable of measuring biological components accurately, and a method for calibrating the device. The device measures a sample including a body fluid taken through a body fluid sampler by sending it with a pump through a sample channel to a sensor. The device further includes a calibrating liquid channel through which a calibrating liquid can be supplied to the sensor via the sample channel by a switching of a first flow path changeover valve placed in the sample channel at a location upstream of the pump and connected to the channel. The method includes introducing the calibrating liquid in the calibrating liquid channel, via other channels, into the sensor by switching the valve.

  • Patent number: 8216525
    Abstract: A modular microfluidic system includes modules which are arranged next to each other in a row. Every module has a microfluidic part which rests on a contact surface of the module in a locally limited area and is forced against the contact surface by a fastening element. The microfluidic part includes a fluid channel system with fluid connections that are arranged on the top surface of the microfluidic part in edge areas relative to the adjoining microfluidic parts. The fluid connections of adjoining microfluidic parts are interlinked by respective connecting channels in a connecting part bridging the microfluidic parts, wherein the connecting part rests on the microfluidic parts in the edge areas. A clamping part rests against the lower surfaces of the adjoining microfluidic parts and is connected to the connecting part via an additional fastening element in the area between the microfluidic parts.

  • Patent number: 8216526
    Abstract: A microfluidic device is described, capable of generating multiple spatial chemical gradients simultaneously inside a microfluidic chamber. The chemical gradients are generated by diffusion, without convection, and can either be maintained constant over long time periods, or modified dynamically. A representative device is described with a circular chamber in which diffusion occurs, with three access ports for the delivery and removal of solutes. A gradient typically forms in minutes, and can be maintained constant indefinitely. Gradients overlapping with different spatial location, and a controlled rotation of a gradient formed by diffusion are demonstrated. The device can also be used to evaluate chemotactic responses of bacteria or other microorganisms in the absence of convective flow.
