  • Thermal regulation of rotors during centrifugation
    Patent number: 11660617
    Abstract: The present invention provides centrifuges (e.g., analytical centrifuges) comprising a cooling assembly having a cooling surface disposed inside the centrifuge chamber and spaced apart from the rotor. The cooling surface disposed inside the centrifuge chamber, spaced apart from the rotor, and configured to exchange heat between the cooling assembly and the rotor, the thermal element thermally coupled to the cooling surface, and configured to control the temperature of the cooling surface.
    Type: Grant
    Filed: September 13, 2017
    Date of Patent: May 30, 2023
    Assignee: Beckman Coulter, Inc.
    Inventors: Thomas Ramin, Eric Von Seggern, Brad Hunting, Joe Schorsch

  • Sorting flow cytometer
    Patent number: 10190959
    Abstract: A sorting flow cytometer identifies an undesirable drop charge sequence that is preassigned to adjacent drops before the drops have separated from a fluid stream. An example of an undesirable drop charge sequence is a sequence of adjacent drops that are charged with sufficiently high opposing charges that, after the drops are formed, would result in merging of the adjacent drops. The sorting flow cytometer adjusts the assignment of drop charges to avoid the undesired drop charge sequence.
