  • Patent number: 11579053
    Abstract: Systems and methods that enable automated processing of specimens carried on microscope slides are described herein. Aspects of the technology are directed, for example, to automated slide processing apparatuses capable of dispensing liquids onto microscope slides. Additional aspects of the technology are directed to methods of replacing a reagent pipette in automated slide processing apparatuses. The apparatus can include, for example, a reagent pipette assembly including a reagent pipette moveable between at least one loading position for obtaining reagent from a reagent container at a filling station and at least one dispense position. The apparatus can also include a retainer for releasably securing the reagent pipette. In some embodiments, the reagent pipette assembly includes a locking mechanism for transitioning the retainer from an open configuration for receiving a pipette and a closed configuration for securing a pipette, in e.g., an aligned position within the retainer.

  • Publication number: 20220268673
    Abstract: At least some embodiments of the technology are directed to an automated slide processing apparatus configured to apply at least one reagent to a specimen carried by a microscope slide. The slide processing station can include a support element with a support surface, at least one vacuum port, and a sealing member having a non-round shape. In an uncompressed state, the scaling member can extend upwardly beyond the support surface. In a compressed state, the scaling member can be configured to maintain an airtight seal with a backside of the microscope slide as the microscope slide is pulled against the support surface by a vacuum drawn via the at least one vacuum port.
