  • Patent number: 10639662
    Abstract: A method dispenses and/or aspirates a predetermined volume of fluid from a chamber. The chamber includes a lower portion containing fluid and an upper portion containing gas. The method includes measuring an initial pressure in the upper portion and introducing or evacuating a known quantity of gas into or out of the upper portion. The volume of gas in the upper portion is determined based on the volume of gas introduced or evacuated from the upper portion and a measured change in pressure in the upper portion. An upper portion target pressure that will dispense or aspirate a predetermined volume of fluid is determined. A controllable valve is opened while the pressure in the upper portion of the chamber is monitored. Once the target pressure is reached, the predetermined volume of fluid has been dispensed or aspirated, and the controllable valve is then closed.

  • Patent number: 8940541
    Abstract: The present invention discloses a sample sorter system adapted to receive and sort samples according to predetermined criteria. The sample sorter system comprises a receptacle that is adapted to receive and retain fluid and samples. The receptacle is operatively coupled with a drive and with a power source such that actuation of the drive causes the rotation of at least one circular component, which in turn causes the development of a flow regime in the receptacle such that the samples suspended in the fluid are conveyable along a closed path to at least one sample handling site that are positioned along said closed path.

  • Patent number: 7727476
    Abstract: A device for aspirating and dispensing liquid samples comprising a pump that comprises a cylindrical chamber, a piston movable in this cylindrical chamber, and a piston drive that engages the piston. The device further comprises a tip connected to the cylindrical chamber with a line, and a channel system that discharges into the cylindrical chamber for flushing or rinsing the latter. The device is characterized in that the piston entirely seals this cylindrical chamber from the channel system, if the piston is positioned in the cylindrical chamber in such a way that a free piston end comes to rest between the channel system and the line. Preferably, the cylindrical chamber is located in a cylinder block, which comprises two parts that are separated by and enclosing an intermediate channel system. The channel system most preferably is implemented as a coherent cavity. According to a first embodiment, the cylindrical chamber is implemented as a sleeve that is inserted in a boring located in a cylinder block.
