An automated biologic sample extracting system from a set of biological samples with a small footprint with minimal movement of the set of consumables, thereby reducing potential contamination during the extraction process. The extracting system comprising a set of reaction tubes, a storage unit to store a set of consumables; a sample preparation unit; a sample extraction unit; a waste unit; a plurality of robots to move tubes, samples, and boxes, and a programmable control system programmed to process samples in a serial pattern in which a series of samples follow one another to be processed in a time sequence and in succession so that it keeps a fixed processing turnaround time of each sample no matter when a sample would start the process.

A receptacle holder having a base body, a first perimeter wall which at least partially protrudes from the base body, and a plurality of resilient elements, which are distributed about a first axis of the receptacle holder and are detachably connected with the first perimeter wall, and wherein each resilient element comprises a first end portion and a second end portion, and wherein each second end portion rests hooked over an edge of a portion of the first perimeter wall, and wherein the receptacle holder is configured to allow sliding of each second end portion in a direction perpendicular to the first axis.

This invention relates to an apparatus for conducting immunoassay test. The apparatus includes a groove unit having a groove along a vertical direction configured to hold a rod-shaped portion of a probe along the vertical direction, and a push pin configured to move along a horizontal direction, the push pin being capable of residing at a first position and a second position. A tip of the push pin is capable of pressing the rod-shaped portion of the probe against the groove when the push pin resides at the first position. The distance between the tip of the push pin and the groove is larger than a diameter of the rod-shaped portion of the probe when the push pin resides at the second position.

Methods for image-based detection of the tops of sample tubes used in an automated diagnostic analysis system may be based on a convolutional neural network to pre-process images of the sample tube tops to intensify the tube top circle edges while suppressing the edge response from other objects that may appear in the image. Edge maps generated by the methods may be used for various image-based sample tube analyses, categorizations, and/or characterizations of the sample tubes to control a robot in relationship to the sample tubes. Image processing and control apparatus configured to carry out the methods are also described, as are other aspects.

Aspects of the present disclosure relate to a method and/or a device for carrying out chemical, biochemical and/or immunochemical analyses of liquid samples, which are present in a sample store of an automatic analyzer, with the aid of liquid reagents which are present in at least one reagent store of the analyzer. In one example embodiment, the automatic analyzer includes cuvettes, a first pipettor, a device with an optical measurement unit, a device for heterogenous immunoassays, a cuvette washing unit, a needle washing unit, a temperature control unit.

Systems and methods for handling a variety of sample and preparatory fluids in a rack specifically configured for compatibility with predetermined liquid handlers such as automated pipettors or multi-channel manual pipettors and set up for magnetic based sample preparation. The rack can hold all of the necessary sample and reagent vials, and present them to the pipettor in some embodiments in a way that allows for parallel operation. The rack includes slidable magnets that in some embodiments are actuatable directly by the pipettor, eliminating a layer of complexity. Combined with a suitable pipettor the magnet enabled rack supports a multistep magnetic based sample preparation capability in a high throughput manner at one station that enhances sample purity throughout magnetic separation processes.

The purpose of this invention is to provide an automated analyzer that is capable of photographing operations at a plurality of processing units while suppressing manufacturing cost growth. This automated analyzer comprises a plurality of processing units for carrying out operations related to analysis, a plurality of measurement instrument mounting parts that are disposed in each of the plurality of processing units and upon which a measuring instrument for measuring the operations of the plurality of processing units can be mounted, and a control unit for controlling the plurality of processing units. The plurality of measurement instrument mounting parts are configured such that the measuring instrument can be removed from each of the measurement instrument mounting parts and such that after being removed from one measurement instrument mounting part, the measuring instrument can be mounted on another measurement instrument mounting part.

A sample testing system comprising: a transporting apparatus; a testing apparatus for obtain a sample and performing testing on the obtained sample; and a controller. The controller executes operation of: controlling the transporting apparatus so as to transport the sample rack in first direction, such that each sample container held in a sample rack is transported to a obtaining position on which the testing apparatus obtains a sample and then the sample rack is transported toward the second position; changing, when retesting of a sample contained in a sample container is necessary, the transporting direction from the first direction to second direction, and then controlling the transporting apparatus so as to transport the sample container accommodating the sample, for which retesting is necessary, to the obtaining position again. Sample testing method and a computer program product are also disclosed.

An optical measurement device is provided. The device includes first and second optical fibers; first and second reaction vessels, and a light guide stage coupled to the first and second optical fibers. The light guide stage is driven to simultaneously optically connect the first and second optical fibers with the first and second reaction vessels. The device includes a measurement device for receiving emissions from the first and second reaction vessels, and a connecting end arranging body that supports the first and second optical fibers along a path. The arranging body is driven along the path between a first position, in which the first optical fiber is optically connected with the measurement device so that light is transmittable from the first reaction vessel, and a second position, in which the second optical fiber is optically connected with the measurement device so that light is transmittable from the second reaction vessel.

A sample rack includes a housing that has multiple spaces or compartments each for receiving and retaining sample containers of various sizes. The sample rack includes dual hooks on the ends for engaging a sample rack handling system. Chamfers formed in the housing of the sample rack assist in placing and removing the sample rack from a sample rack handling system. The sample tube rack also includes a handle that extends upward from one end and includes gripping features. A groove and bar, incorporated into each sample rack, are able to selectively interlock with adjacent racks to assist in lifting multiple sample racks together.
