  • Publication number: 20240167921
    Abstract: Various examples of systems and methods are provided for slide processing. In one example, among others, a system for processing microscope slides includes a reservoir having a fluid and a treatment applicator that can dispense the fluid on a slide. The treatment applicator can include offset rails on opposite sides of an application surface, the offset rails and application surface defining a treatment channel when positioned on a surface of the slide; and an opening that can direct the fluid to the treatment channel. The opening can include a constriction configured to modulate flow of the fluid into the treatment channel. In another example, a method includes positioning a slide adjacent to a treatment applicator and dispensing a fluid into a treatment channel along the surface of the slide through an opening extending through the treatment applicator.

  • Publication number: 20240139744
    Abstract: Various examples are provided related to slide preparation. In one example, a slide preparation apparatus includes a support surface, an upper surface opposite the support surface, and a sample tube holder. The upper surface can include a slide channel extending to a stop, a fiducial mark disposed in the slide channel, and a support bar extending across the slide channel. The sample tube holder can secure a sample tube in a vertical position adjacent to an end of the upper surface adjacent to the stop. When a syringe is supported by a sample tube positioned in the sample tube holder, a needle of the syringe can be aligned with the fiducial mark when it is seated in a guide groove of the support bar.

  • Publication number: 20230160793
    Abstract: Various examples of systems and methods are provided for slide processing. In one example, among others, a system for processing microscope slides includes a slide positioner that can adjust a position of a slide and a slide treatment system that can dispense a micro stream of a fluid at a location on the slide when the slide is positioned beneath a jet nozzle of the slide treatment system. The system can include a slide sled that can align a smearing slide with a surface of the slide including a fluid sample is disposed, and support the smearing slide at a predefined angle with respect to the surface of the slide. In another example, a method includes obtaining a slide including a sample disposed on a surface, positioning the slide below to a jet nozzle, and dispensing a micro stream of a fluid onto the sample using the jet nozzle.
