Provided is an automatic analyzer capable of further reducing carryover between specimens. The automatic analyzer includes a first dispensing unit for dispensing a specimen related to a first analysis item group having a high possibility of carryover, a second dispensing unit for dispensing a specimen related to a second analysis item group having a low possibility of carryover, an input unit for receiving an input of analysis information related to a plurality of analysis items for a specimen, a classification unit for classifying the analysis information into the first analysis item group and the second analysis item group, and a determination unit for determining a dispensing sequence for each specimen for the first analysis item group and determining a dispensing sequence for each analysis item for the second analysis item group.

An automatic analyzer has a supply unit that stores and supplies a liquid to be used by the analyzer, an analyzer circulation system that circulates the liquid within the analyzer, and a supply unit circulation system that circulates the liquid within the supply unit. An analysis controller switches a flow rate of the liquid circulated by at least one of the analyzer circulation system and the supply unit circulation system between a first flow rate in a normal state and a second flow rate different from the first flow rate. Consequently, by suppressing fungal propagation within a circulation flow path for a liquid, compared to conventional techniques, the frequency with which a liquid is replaced and the frequency with which the inside of a reaction tank is cleaned are reduced and a time period for a maintenance operation by an operator is reduced.

An automatic analyzing apparatus according to the present embodiment includes a specimen container, a piercer, a detector, and processing circuitry. The specimen container is a container in which a specimen is housed, an opening of the specimen container being sealed by a cap. The piercer pierces the cap by a distal end. The detector detects a blot on the cap. The processing circuitry controls a piercing operation of the piercer.

A switching valve includes a rotor having a pair of rollers rotatably mounted on both ends thereof, a rotor drive unit rotationally driving the rotor, a pair of pressing members, each being provided at a position where each of the pair of pressing members cooperates with each of the pair of rollers outside a revolution orbit of each of the pair of rollers revolving by rotation of the rotor, and a pair of tubes, each being disposed between the revolution orbit of each of the pair of rollers and each of the pair of pressing members. A rotation center axis of the rotor is disposed on a straight line connecting centers of rotation of the pair of rollers, and each pressing member has the pair of pressing areas symmetrical with respect to a straight line passing through the center of rotation of the rotor and extending a vertical direction.

A method for collecting and delivering biological samples to a destination, such as an analyzer are provided herein. In one example, a plurality of samples, each including particles, is obtained from respective wells of a sample source having a plurality of wells. The plurality of samples are introduced into a fluid flow stream contained within a conduit having an inner diameter and in communication with a destination. An inner surface of the conduit is coated with a hydrogel barrier substance, such as poly-HEMA. The fluid flow stream is guided through the conduit to a destination. In one example, the destination may be a flow cytometer. Methods of preparing a poly-HEMA solution and coating the inner surface of a conduit with poly-HEMA are also provided.

Devices and methods for providing and dispensing opposables onto slides are provided in which magazines loaded with opposables include retention arms to reduce movement of the opposables during shipment and processing and to reduce or eliminate contamination.

An online liquid autosampler may include a pipette, a depyrogenation system, a sample source, and a movement system. The depyrogenation system may be configured to selectively depyrogenate the pipette. The sample source may be configured to provide a liquid to be sampled to the pipette. The movement system may be coupled to one or more of the pipette, the depyrogenation system, or the sample source. The movement system may be configured to: position the pipette within the depyrogenation system for depyrogenation; position a tip of the pipette within the sample source to aspirate a sample of the liquid from the sample source; and position the pipette to dispense an aliquot of the sample of the liquid into an aliquot sample target.

The present disclosure relates to a trackable precise-sample-injection device for a multi-well plate and, more specifically, to a trackable precise-sample-injection device for a multi-well plate, the device being capable of: preventing cross-contamination that can occur when many samples are manually put into a multi-well plate, and a diagnosis error caused by the injection of a sample into the wrong well or repeated injection; and simply recording and tracking information about wells into which samples are injected. The present disclosure relates to a trackable precise-sample-injection device for a multi-well plate, the device being capable of being efficiently used for a pooling inspection, and the like by injecting a plurality of samples into a multi-well plate.

A sample testing system includes a test receptacle support structure, an optical element positioned for transmitting electromagnetic radiation emitted or reflected by a sample disposed in a test receptacle supported by the test receptacle support structure, a cleaning member, and an automated transport arm configured to (i) detachably couple the cleaning member, (ii) move the detachably-coupled cleaning member into a position proximate to and/or contacting the optical element, and (iii) decouple the cleaning member.

A sample analyzer comprises a reagent container setting part configured to install a reagent-container retainer for retaining a reagent container having an opening, an aspirating tube configured to aspirate a reagent in the reagent container, and an aspirating tube holder configured to hold the aspirating tube. The aspirating tube holder includes a cover, the cover having an open portion provided from a bottom face thereof to a side face thereof, the cover covering the aspirating tube with a region thereof other than the open portion. The aspirating tube holder includes a guide portion configured to guide the aspirating tube holder relative to the reagent-container retainer such that the aspirating tube holder is allowed to reach a state where the aspirating tube has entered the reagent container or a state where the aspirating tube has retreated from the reagent container.
