摘要:
A device (1) is disclosed comprising linearly arranged receptacles (10) to receive containers (2) filled with liquid to be analyzed and cover means (6) for the openings (20) of the containers. Each receptacle (10) includes a lid (60) which is movably arranged on a retainer (70) and associated with an opening (20) of a container (2). Lid (60) can be pivoted about a horizontally extending axis of rotation (63) of retainer (70) from a covering position 61 to an uncovering position 62. Pivoting of lid (60) is effected by means of an arm (71) arranged on retainer (70) which arm is manually actuated if the device (1) is outside the analyzer and actuated by means of an actuating element (30) of an actuating means (3) if the device (1) is arranged within the processing station (4) of the analyzer. Retainer (70) includes a cam (74) which is concentrically arranged to the axis of rotation (63) and which is engaged by a hold-down means (75) by means of which lid (60) is retained in its covering position (61). Each receptacle (10) is associated with a sensing mark (13) which by means of a sensor (14) arranged in the area of the actuating means (3) permits the device (1) or the container (2) to be aligned with the aspirating head (41) of a processing station (4) for removal of liquid to be analyzed. Lid (60) consisting of resilient plastic material is designed as a sealing means (64) on its bottom side to prevent the liquid to be analyzed from being evaporated, contaminated or spilled.
摘要:
A device is privided for feeding objects into a waste bin (3) of an analyzer comprising a transport path (4), a transport carriage (5) for a tray (7) carrying a container (6) and a processing station (8) having an aspirating head (80) for substances to be analyzed. A feeding chute (1) is removably arranged on a retainer (2) within the transport path (4), held by a resetting means (22) in its feeding position, and can be pivoted to its end position (11) lying outside the transport path (4) by means of a transport carriage (5) driven by a microprocessor-controlled stepper motor (40). Means (12) are arranged on feeding chute (1) forming part of the transport path (4) when the chute is in its end position. Retainer (2) includes a blocking element (20) which in the retainer's end position (21) and with the feeding chute (1) being removed projects into the transport path (4) and limits the travel of the transport carriage (5), resulting in a reduced stepping number of stepping motor (40) when returning the transport carriage (5) until a sensor (9) is reached in the area upstream of feeding chute (1). A control unit then shuts down a processing station (8), in particular the dumping of a used pipette (81) from aspirating head (80) and thus contamination of the substances to be analyzed or the analyzer itself is prevented.
