  • Sample liquid aspirating and dispensing probe
    Patent number: 5133218
    Abstract: The sample liquids analysis system includes a probe which is automatically operable to successively aspirate sample liquids and reagent and/or other sample liquids processing liquids and to dispense the same in turn into sample liquids analysis apparatus for automatic, successive sample liquids analyses. Isolation liquid supply apparatus are operatively associated with the sample liquids aspirating the dispensing probe and operate to introduce an isolation liquid which is immiscible with the sample liquids and which selectively wets the probe to the substantial exclusion of the sample liquids, to the probe to, in combination with operatively associated rinse liquid supply apparatus which operate to fill the probe with a rinse liquid between successive sample liquids aspirations, reduce sample liquids carryover to ultra low levels.
    Type: Grant
    Filed: April 15, 1991
    Date of Patent: July 28, 1992
    Assignee: Tritech Partners
    Inventors: Kenneth F. Uffenhiemer, Nicholas F. Di Domenico
