A guiding frame for a laboratory automation device comprises: a bottom side for placing the guiding frame on a component of the laboratory automation device; a top side with a position detection area; and an opening for accessing a port of the component, which opening is arranged besides the position detection area. The position detection area has two recesses, each recess having two straight edges, which from a view direction onto the top side are arranged inclined with respect to each other. The bottom side comprises alignment means for aligning the guiding frame with respect to the component, the alignment means comprising a base surface for contacting a top surface of the component and/or guiding surfaces for contacting walls of the component.

Disclosed is an analyzer comprising: a liquid container mounting section in which a liquid container are set; a container mounting section in which at least one tip container accommodating a plurality of pipette tips is set; a cover detecting section that detects a presence of a cover mounted on the tip container; a dispensing section that equips a pipette tip accommodated in the tip container and dispenses a quantity of liquid from the liquid container to a reaction container via the equipped pipette tip; a detecting section that interrogate a property of the liquid; and a controller programmed to prohibit a process of equipping the pipette tip by the dispensing section when the cover on the tip container is detected, and permits the process when no cover is detected.

A device for determining a position and/or an extension of a drop in a position determination space, where the device has a camera having an objective and a beam splitter in the recording area of the camera, and the device is designed in such a way that light coming from the position determination space can enter the objective of the camera along a first light path as well as along a second light path, where light along the first light path can be reflected at a first reflector element in the direction of the beam splitter and can be transmitted through the beam splitter towards the objective, and where light along the second light path can be reflected at a second reflector element in the direction of the beam splitter and can be reflected at the beam splitter towards the objective.

The present invention determines whether or not a mounted tip and a dispensing amount match with each other in order to prevent contamination in a dispensing device. The present invention is provided with a pipette mechanism 108, 109 that performs suction and discharge, a motor 102 that drives the pipette mechanism, and a pressure sensor 113 that detects a pressure of the pipette mechanism. A dispensing tip 110 is mounted to the pipette mechanism. A control computer 116 controls the motor 102, drives the pipette mechanism in a suction or discharge direction, and determines a type of the dispensing tip 110 on the basis of a difference in pressure waveform detected by the pressure sensor 113.

A detection device detects a position of a leading end of a tip for executing an operation on a cell via the leading end. The detection device includes a light source that outputs light in a lateral direction such that the light has a width when viewed along an up-and-down direction, a movement mechanism that moves the tip, and a detector that detects the light output from the light source, wherein the light output from the light source until being detected by the detector includes first and second lights that advance in respectively different lateral directions, the movement mechanism moves the tip such that a part of the first light and a part of the second light are blocked by the leading end, and the detector detects the first and second lights whose parts are blocked by the leading end.

An insert mounted in a mixing cup and used by an automated chemical analyzer for removing a targeted component of a liquid sample includes a porous matrix formed of or carrying in an immobilized state functionalized particles having properties such that the targeted component of the liquid sample adheres to the functionalized particles. When the liquid sample is expelled from a disposable tip fitted on the end of a pipette forming part of the automated chemical analyzer into the mixing cup, the liquid sample is drawn into the matrix of the insert by capillary action, whereupon the targeted component of the liquid sample adheres to the immobilized functionalized particles of the matrix.

A blood gas analyzer for performing a measurement of analytes in a blood sample, such as a whole blood sample, aspirated into the blood gas analyzer from a handheld blood sample container includes a controller, and a sensor system for detecting a presence, a position and/or an orientation of the handheld blood sample container relative to an inlet structure. An aspiration system is provided for aspirating the blood sample from the handheld blood sample container, the aspiration system connectable to the handheld blood sample container. A user interface system is provided for outputting instructions to a user of the blood gas analyzer, the instructions being selected among pre-stored sets of instructions. The controller selects one of the at least two pre-stored sets of instructions based on an assessment of a signal retrieved from the sensor system.

A sampling device 1 includes: an electrode nozzle 2, a nozzle moving mechanism moving the electrode nozzle 2 in a vertical direction, a dispensing tip 3 attached to the electrode nozzle 2, a positive electrode 5a and a negative electrode 5b attached to the electrode nozzle 2 and extending along the dispensing tip 3, a current detector 7 detecting a value of a current flowing between the positive electrode 5a and the negative electrode 5b, a sample container housing a sample solution, and a controller controlling the nozzle moving mechanism. The controller drives the nozzle moving mechanism to move the electrode nozzle 2, specifies a position of a predetermined component layer from variation of the value of the current, and the dispensing tip 3 in the vertical direction, and drives the electrode nozzle 2 to sample the predetermined component layer.

The invention has an object to provide an automatic analyzer and a control program that can shorten total analysis time. The automatic analyzer comprises: a sample rack that houses a sample; a sample dispensing mechanism that aspirates the sample from the sample rack and dispenses the sample into a reaction container; a plurality of detection units that detect a reaction liquid in the reaction container; and a control unit that controls the sample dispensing mechanism and the detection units. The control unit checks the measurement item specified for the sample and checks one of the detection units that is specified by the measurement item. When measurements specifying the same detection unit among the detection units are specified consecutively, the order of dispensing by the sample dispensing mechanism is changed so that measurements specifying different detection units are made consecutively.
