The present invention relates to an autosampler. The autosampler includes a sampling needle, a swing arm, a main shaft, a synchronous rotating pulley, and a rotating shaft sleeve. One end of the swing arm is fixed to the main shaft, and the other end thereof is fixed with the sampling needle for supplying a sample. The rotating shaft sleeve is installed in the synchronous rotating pulley, and the rotating shaft sleeve is mounted on the main shaft. The main shaft can rotate around the central axis of the main shaft in synchronization with the rotating shaft sleeve, and can move up and down in the direction of the central axis with respect to the rotating shaft sleeve. The autosampler is characterized in that it further includes a contact member.

The contact member penetrates the synchronous rotating pulley and the rotating shaft sleeve from one side of the synchronous rotating pulley in the radial direction thereof until it comes into contact with the main shaft. The contact member is in rolling contact with the main shaft. According to the present invention, the contact member may provide a radial force to the main shaft so as to eliminate a fitting gap between the main shaft and the rotating shaft sleeve, and may reliably fix the synchronous rotating pulley and the rotating shaft sleeve so as to ensure the accuracy and reproducibility of the injection position.

A method for measuring optical signal detector performance that includes directing light emitted from an optical signal detector onto a first non-fluorescent surface portion in a first detection zone of the optical signal detector. A first characteristic of light detected by a first sensor of the first optical signal detector is measured while the first non-fluorescent surface portion is in the first detection zone of the optical signal detector. Light emitted from the optical signal detector is directed into a first void in the first detection zone of the optical signal detector. A second characteristic of light detected by the first sensor of the optical signal detector is measured while the first void is in the first detection zone of the optical signal detector. And an operational performance status of the optical signal detector is determined based on at least one of the first characteristic and the second characteristic.

Described is an apparatus for controlling a position of a sample in a liquid chromatography system. The apparatus includes a rotary drive mechanism, a stepper motor and a rotational coupling system such as a drive belt and pulley system. The rotational coupling system transfers the rotational motion of a motor shaft to a shaft of the rotary drive mechanism. Advantageously, the stepper motor is remote to the sample compartment for improved safety in the event that volatile gas accumulates within the sample compartment. The rotary drive mechanism can be configured in a small form factor and can provide highly stable rotation of an attached sample tray to accommodate the requirements of compact liquid chromatography systems. In addition, leakage from inside the sample compartment to the ambient environment is substantially reduced or eliminated, resulting in better thermal control of the sample compartment.

Disclosed is an automated liquid-phase immunoassay apparatus used with a cuvette having a plurality of chambers containing a reagent necessary for detection of an analyte in a biological specimen. The apparatus includes a movable cuvette module equipped with the cuvette, an optical reading module for optical assaying of a material resulting from a reaction between the specimen and the reagent, and a dispenser module which is positioned on the cuvette module and which dispenses the specimen and the reagent to the plurality of chambers of the cuvette and washes the specimen and the reagent therefrom.

An automated analyzer is provided with one or more dispensing lines 109, 209 that are each for loading and unloading, at one end thereof, a sample rack 101 having placed therein one or more sample containers accommodating a sample for analysis and for conveying the sample rack back and forth from a dispensing position for dispensing the sample from the sample containers and sample rack removal parts 111, 211 that are provided adjacent to the other ends of the dispensing lines 109, 209 and provide and receive sample racks to and from the dispensing lines 109, 209. According to this configuration, it is possible to convey an urgent sample while suppressing device complexity, preventing cost from increasing, and also maintaining speed.

A system including an optical signal detector and a controller operatively coupled to the optical signal detector and configured to determine an operational performance status of the optical signal detector. The optical signal detector includes a detection channel having a light source and a sensor, where the detection channel is configured to emit and focus light generated by the light source at a detection zone and to receive and focus light on the sensor. The optical performance status of the optical signal detector is based on a measured characteristic of light focused on the sensor while a non-fluorescent surface is in the detection zone and/or a measured characteristic of light focused on the sensor while a void is in the detection zone.

The present invention provides a production-line-type high-throughput screening system, which relates to the field of biotechnology and testing equipment. The system comprises of four manipulators, three parallel conveyor belts with fixed slots, 2-DOF slipway and fixed fixtures, 96-channel pipetting system, coloring device, oscillating mixing device, microplate reader, well plates loading platform and well plates recycling platform.

Disclosed is a station, for testing an analyte in a sample, enabling accurate and quick reaction and analysis of the sample and a reagent in one apparatus. To this end, the present disclosure provides a station, which is for testing a sample by means of inserting a cuvette, having a standby chamber on which a collecting member is placed, a sample chamber, a reagent chamber and a detection unit. The station comprises: a housing which has an input/output part into which a cuvette is inserted; a driving unit which is provided inside the housing, horizontally moves the cuvette, vertically moves a collecting member, reacts a sample in a sample chamber and a reagent in a reagent chamber, and injects a reaction result thereof into a detection unit; and an optical reader which is provided on the horizontal movement path of the cuvette and is for analyzing the reaction result.

An apparatus for conveying a plurality of articles includes a transport belt, a bumper stopper, and a rotator. A motor moves the transport belt which is adapted to rotate the rotator as the belt conveys the plurality of articles. The stopper can move between first and second positions relative to the transport belt wherein the bumper stopper guides one article toward the rotator when the bumper stopper is in the first position. The bumper stopper allows the article to be conveyed to another location when the bumper stopper is in the second position. The transport belt can continue to convey other articles while the one article is temporarily held in place by the bumper stopper. The rotator is configured to rotate the article conveyed by the transport belt. The article can remain in contact with the transport belt while the rotator is rotating the article.
