    摘要: A tray and conveyor for the trays are described, for moving liquid samples in an analyzer. The tray comprises a base having a magnetic member for responding to a magnetic field, a tray frame and member for freely rotatably mounting the frame on the base, the tray frame comprising a plurality of receptacles constructed to receive either sample tubes or aspirating tips useful to aspirate sample from a tube, the receptacles including a fixed bottom support. The conveyor comprises a support, conveying members under the support comprising a plurality of magnets and members for generating a moving magnetic field with the magnets, the conveying members being mounted in a continuous loop under the support and the support being permeable to a magnetic field, one of the above-noted trays being mounted above the support on the base.

    摘要: A stack of a plurality of substantially identical cup-like vessels pre-incorporated with reagent on the inside, each of the vessels occupying at least about 50% of the depth of the next adjacent vessel to maximize stacking density. Because the pre-incorporated reagent overlaps the occupied depth portion of the vessel and therefore runs a risk of being dislodged, the wall of the vessel is constructed to provide a gap between the inside surface bearing the reagent, and the outside surface of the occupying, nested vessel, that is at least 0.025 mm.

    摘要: A clinical analyzer moves a stack of slide or cup-like test elements into position for dispensing by a plunger and a driver featuring a housing around the plunger, a spring for biasing the plunger to project beyond the housing, a connection between the housing and the driver, and two sensors. The first sensor senses the initial movement of the housing and plunger toward the stack, and the second sensor senses movement of the plunger against the spring back into the housing upon contact with the stack.

    摘要: There is disclosed a pipette and a method of using the pipette in which an active element of the pressurizing system is a bellows within a piston chamber, operated by a motor. To achieve the advantages of the invention, including ease in manufacturing and the ability to actuate a tip ejector, the bellows is mounted so that the outside surface of the sidewall of the bellows, together with the piston chamber, defines the air volume operative on a fluid passageway leading to a disposable tip.

    摘要: There is disclosed a pipette useful with disposable tips, comprising a plurality of differently-sized pistons and a piston chamber for each piston. Each piston chamber has a vent passageway extending to the exterior surface of the pipette. The pipette is improved in that the mounting means for mounting a disposable tip comprises, not one surface, but a plurality of differently-sized surfaces. Furthermore, the vent passageway for all but the smallest piston chamber exits at a location in between the mounting surface for the tip of that particular piston chamber and the next smaller mounting surface, whereby the larger disposable tips seal over the vent passageways of the smaller disposable tips.
