A dispensing probe driving mechanism moves the dispensing probe between prescribed positions of the microchip and the container.
Abstract: A method for positioning a sample in a diagnostic analyzer includes: providing two or more sample carriers on a conveyor; providing a fixed registration element for each sample carrier at predetermined locations along the conveyor; providing a flexure device positioned between the sample carrier and the conveyor; advancing the sample carrier beyond the fixed registration elements; reversing the conveyor direction to back at least one of the sample carriers into contact with its corresponding registration elements; continuing to reverse the conveyor until all sample carriers are in contact with their respective registration elements; whereby the flexure elements of the sample carriers in contact with the respective registration elements will deform as the conveyor reverses to allow all sample carriers to contact their respective registration elements, thereby providing a known position of the sample carrier.
Abstract: A sample card for use in a spectroscopic analytical instrument. The card is preferably disposable and includes an aperture through the card in which there is positioned a sample supporting window on which a sample is adapted to be placed. The sample supporting window is made from a light energy transmitting material by one of the steps such as cleaving, fly cutting, chipping milling, sawing or scaling. A method of manufacturing the card and for using the card are also included where the method includes the step of providing light supporting window by forming that window by the aforedescribed processes.
Abstract: A histological specimen cassette for use in connection with a larger histological specimen cassette, wherein each histological specimen cassette has an internal chamber that includes a receptacle and a lid, the receptacle having a bottom wall, opposite side walls, opposite front and back walls, and an internal chamber or cavity, where the internal chamber or cavity is positioned between the sidewalls, the front and back walls and partially bound by the bottom wall, having a plurality of apertures that extend through the bottom wall and that create fluid passageways into the cavity, the lid having a plurality of apertures that extend through the lid and that create additional fluid passageways into the cavity, the histological specimen cassette being dimensioned such that the histological specimen cassette can fit entirely within the void of the larger histological specimen cassette when the lid is in the closed position.
Abstract: A reagent cup device 1 includes a plurality of individually sealed reagent cup compartments 7, each holding a reagent cup 8 having an open end and an inner surface, at least part of which is coated with a chemical reagent. Each reagent cup compartment 7 is closed and has a first end covered by a first breakable seal 5 and a second end covered by a second breakable seal 10. Since the reagent cup compartments 7 are individually sealed by the breakable seals 5, 10, it is possible to gain access to the interior of a reagent cup compartment 7, and thereby to the reagent cup 8 held therein, without breaking the sealing of the remaining reagent cup compartments 7. Thereby degradation of the chemical reagent in the reagent cups 8 is reduced, and the expected lifetime of the reagent cups 8 is accordingly increased. The breakable seals 5, 10 may be provided with weakened zones in order to easier break the seals 5, 10 when access is desired.
Abstract: Kits and methods for qualifying automated biological screening system. At least one biological specimen having a plurality of marked target zones (MTZs) exhibiting an attribute is provided. The biological specimen(s) is processed through the automated biological screening system to determine locations of biological objects suspected of exhibiting the attribute. The locations of the MTZs can be compared to the locations of the suspicious biological objects in order to determine a number of matches. The automated biological screening system can then be qualified based on the number of matches, and optionally based on statistical information related to the biological specimen. The statistical information can be acquired by processing the biological specimen through a qualified automated biological screening system over a number of runs.
