  • Publication number: 20140165711
    Abstract: A system for collection and delivery of sub-milliliter liquid samples is described that provides a dramatic simplification for the measurement of clinical values. The system produces high dilutions of capillary size samples, such as bodily fluids or blood, by a factor of 1000 or more. Multiple assays can be conducted on a sample of 0.1 cc or less. A small lancet can create a drop of blood on a fingertip or other location, which can be collected into a self-priming capillary blood collector. The sample is then loaded into a consumable loader. Then a fluid, such as saline, is flowed into the consumable loader, and passes through the capillary collector, washing out the fluid. Downstream, the blood in the capillary is reliably diluted by mixing with appropriate reagents to allow analysis of selected blood properties. One or more individual bubbles can be inserted into the stream during loading. The capillary loading system can be used for one or several assays on a single blood sample.

    Abstract: The present invention relates to a device, to a system, and to a method for the preparation and fractioned dispensing of samples of a fluid. The device of the invention comprises a body having formed therein guide means suitable for receiving a sample-taker member and for guiding it in translation through the device, and at least one preparation chamber enabling an aliquot of a fluid sample dispensed into the chamber by a said sample-taker member to be prepared in a stream of a suitable reagent. The guide means pass through the preparation chamber and communicate therewith to enable an aliquot of fluid to be dispensed into the chamber in a determined position of the sample-taker member in the guide means. The preparation chamber has an introduction orifice for introducing at least one reagent into the chamber for mixing the reagent with an aliquot, and at least one dispensing orifice for dispensing the mixture formed by said aliquot and said reagent to recovery and/or analysis means.

  • Publication number: 20130312545
    Abstract: A sealing pipette tip includes features to seal the tip directly against the piston in an air displacement pipette, avoiding the need for a piston seal within the pipette. This configuration reduces potential points of failure, allows the pipette-tip interface to be optimized, and improves liquid handling characteristics of the pipette.

  • Patent number: 8584535
    Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. All conduits by which the disposable tip attaches to the instrument are combined into a single connection point on the upper end of the tip.

  • Patent number: 8580197
    Abstract: In a control method for a computer-controlled liquid handling workstation with a work surface, a motorized pipetting robot with at least one pipette, and a control computer, to which the pipetting robot is connected, a control program activated in the control computer enables the pipetting robot to position the pipette at specific positions on the work surface and to execute a specific action using the pipette. The interface includes an input mechanism, visualization mechanism, interface software, and an electronic memory. The visualization mechanism visualizes the positions at which containers are situated on the work surface of the liquid handling workstation and a selection of the specific actions executable using the pipettes.

  • Patent number: 8573072
    Abstract: A method for removing a fluid substance from a sealed collection device comprising a cap and a fluid-holding vessel, where the method aids in venting air from the collection device when the cap is penetrated by a fluid transfer device used to withdraw a fluid substance from the vessel. Venting is aided by incorporating a pause step between penetrating the cap and contacting the fluid substance held by the vessel with the fluid transfer device or by contacting the cap at a slower speed than the fluid transfer device enters the collection device after the cap has been penetrated.

  • Patent number: 8551788
    Abstract: A method of selecting pipetting parameters of a pipetting device for dispensing or pipetting a specific volume of a liquid sample, includes a fluid column of a fluid chamber of the pipetting device set into oscillation at the beginning of the aspiration, the pressure is monitored with the pressure transducer in the fluid chamber, and the pressure changes generated during aspiration into measuring signals are recorded. These measuring signals are processed by a computer or micro-processor and reproduced as a pressure curve, which is characteristic for the fluid column with the aspirated liquid sample, and which is compared with known pressure curves. Based on this comparison, pipetting parameters of the pipetting device are selected for the dispense or for pipetting a specific volume of the liquid sample. Selectable pipetting parameters include a speed of a movement of a pump piston of the pipetting device.
