  • 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.

  • 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.

  • Patent number: 8182744
    Abstract: Systems and methods to reduce bioburden on at least a portion of a fluid transfer port include supplying a dose of radiation to the portion in optical communication with at least one source of radiation. In an illustrative example, a medical container, such as a vial or IV bag, receives a dose of ultraviolet (UV) energy substantially at a predetermined region of a fluid transfer site. In some examples, such a sanitization process may precede a fluid transfer operation in which a fluid is transferred into or out of the medical container by passing through the sanitized region. Such fluid transfers may be used in automated or semi-automated pharmaceutical processes, such as drug reconstitution. Various embodiments may further include one or more seal assemblies, each seal assembly having an aperture through which the radiation dose is supplied from the source to a controlled region on the fluid transfer port.

  • Patent number: 8137640
    Abstract: Invention methods employ the use of acoustic waves to transfer small amounts of fluid in a non-contact manner. In invention methods, acoustic waves are propagated through a separated pool of a source fluid in such a manner that causes the ejection of a single micro-droplet from the surface of the pool. The droplet is ejected towards a target with sufficient force to provide for contact of the droplet with the target. Because the fluid is not contacted by any fluid transfer device such as a pipette, the opportunities for contamination are minimized. Invention methods may be employed to transfer fluids from an array of source sites to an array of target sites, thereby enabling the precision automation of a wide variety of procedures including screening, and synthesis procedures commonly used in biotechnology.

  • Publication number: 20120039771
    Abstract: A sample treatment apparatus is designed to directly monitor a pressure signal from a pressure sensor to examine pressure fluctuations resulting from a sample's sway before a discharge of the sample, so that the discharge is performed after the confirmation of the absence of pressure changes. The apparatus has a detection function that allows a discharge to be started even before a pressure fluctuation vanishes completely, by allowing the operator to set a desired number of pressure monitorings, monitoring time, or pressure amplitude. The detection function also allows an alarm to be raised when a pressure fluctuation has not fallen within a given range. The sample treatment apparatus therefore allows discharge of more accurate amounts of samples.

  • Publication number: 20110268628
    Abstract: A manually directed, electronic multi-channel pipettor uses servo controlled motors to drive a carriage and pipetting head in response to a user's manipulation of a control handle. The pipetting head include an array of tip fittings, e.g. 96. The system includes a check processor to avoid unintended motion in case of system faults or crashes. The system requires substantial force to attach the array of tips, and therefore includes controls that require both of the user's hands be occupied during the tip attachment process.
