  • Patent number: 8486714
    Abstract: The invention concerns reagent delivery system for an apparatus for processing of biological samples arranged on microscope slides, comprising a reagent section having one or more reagent containers; a slide section in which at least one microscope slide is arranged; a probe for dispensing a portion of reagent onto a predetermined microscope slide, and means for handling the probe. The probe comprises a continuous prove tubing element extending through a rigid probe member and connecting the probe tip to a pneumatic pressure regulation device. The reagent containers are adapted for cooperation with the probe tip. In this manner a high though-put and a very low carry over of fluid residues is achieved since there is no assembled parts making up the inside volume of the probe in which the fluid may be retained.

  • Patent number: 8257968
    Abstract: The present invention concerns an apparatus (1) for staining tissue samples, said apparatus (1) including a reagent section (2) or reagent containers (3); at least one staining section or tissue samples, a robotic head (22) or robotic element (20) that may move reagent to a predetermined tissue sample, said robotic element (20) being moveable above the reagent and the staining sections, a control element (85) that may manage a staining process, a 2-D optical sensor (86) to detect two-dimensional image data of a relevant property and that can feed the captured image data to the control element (86). By providing the robotic element (20) with a 2-D optical sensor (86), a common image processor may be provided having multiple functions. By using a 2-D optical image processing system, the control system of the apparatus may easily be adapted to read various types of data presentations, just as actual images for sections of the apparatus may be identified in order to assess the condition of the apparatus.

  • Patent number: 8216512
    Abstract: The present invention concerns an apparatus for automatic processing at least one biological sample accommodated on a carrier member, such as a slide by applying a predetermined amount of reagents in a predetermined sequence according to a processing protocol, said apparatus comprising; a housing frame; at least one processing section for accommodating at least one slide, the at least one processing section is provided within the housing; a hood cover protecting the at least one processing section in said housing; wherein the hood cover completely encloses the processing section defining an interior space; and wherein the apparatus further comprises climate control device provided to control the environment within the interior space.

  • Patent number: 7875245
    Abstract: The present invention concerns a method and apparatus for automatic processing a biological sample on a carrier, perhaps robotically, by applying predetermined amounts of reagents in a predetermined sequence according to a processing protocol, the processing including pre-treatment steps, under the control of an adaptive processing control system using a sample process parameter input that may be independent and an independent process parameter memory that does not interrupt process operation when being used, such that samples may be added or removed without interrupting the processing of other samples. Also included is an image capture function for sample and reagent identification and process monitoring, as well as temperature regulation and environmental control functions.

  • Patent number: 6746873
    Abstract: A flow cytometry system is disclosed for oscillating the exterior of a flow cytometer nozzle. Oscillating the exterior of a flow cytometer nozzle at selected oscillations or a sweeping range of oscillations disintegrates particles and gas entrapped within the flow cytometer nozzle. Adherents absorbed to the exterior of the flow cytometer nozzle may also be removed. An energy source (1) serves to generate a selected oscillation or range of oscillations. The energy source (1) is connected to a flexible transfer element (2) which conducts the electrical signals to an oscillation system (3). The oscillation system (3) turns the electrical energy from the energy source (1) into mechanical oscillations and is connected to a portable device (4) which disintegrates particles, dislocates gas within the flow cytometer nozzle and cleans the exterior of the flow cytometer aperture.
