The present disclosure provides an in-situ successively fixing rolling type holding device for use in a low-temperature environmental test chamber. The holding device includes a bracket, multiple holding components, and a conveying device. The bracket is fixed in the low-temperature environmental test chamber. The driving mechanism is used for driving the conveying member to rotate, thus making multiple test articles successively pass through the test position in the low-temperature environmental test chamber for the in-situ measurement. The present disclosure can reduce the times of door opening of the low-temperature environmental test chamber during the successive in-situ measurements of multiple test articles in the low-temperature environmental test chamber, thus preventing the door opening and closing of the low-temperature environmental test chamber and the transfer of test article from causing the temperature fluctuation in the temperature field where the test articles are located.

A sample rack moving mechanism is provided for removing a sample rack loaded with one or more sample containers from a temporary storing section, and returning the sample rack loaded with the sample containers holding the tested sample to the temporary storing section. The sample rack moving mechanism may include a drive element, a cam driven by the drive element to rotate and having a curve contour, a cam follower moving following the outer contour of the cam, a guide groove corresponding to the temporary storing section, having a bottom plane of the same height as a support plane of the temporary storing section for supporting the sample rack, and capable of moving the sample rack, and a support element driven by the cam follower to move upward and downward and driving the sample rack to horizontally move between the temporary storing section and the guide groove.

A switch for a conveying line for transporting a laboratory diagnostic vessel carrier is presented. The conveying line comprises a first line portion and a second line portion. The switch comprises a curved first guiding surface and a second guiding surface. The switch is moveable between a first position, in which the laboratory diagnostic vessel carrier is transportable along the curved first guiding surface from the first line portion to the second line portion, and a second position, in which the laboratory diagnostic vessel carrier is further transportable along the second guiding surface on the first line portion. A switch assembly and a conveying line are also disclosed.

Systems and methods are provided for sample processing. A device may be provided, capable of receiving the sample, and performing one or more of a sample preparation, sample assay, and detection step. The device may be capable of performing multiple assays. The device may comprise one or more modules that may be capable of performing one or more of a sample preparation, sample assay, and detection step. The device may be capable of performing the steps using a small volume of sample.

A digital dispense system for preparing and analyzing a plurality of samples. The system includes two or more fluid droplet ejection devices. Each fluid droplet ejection device contains a fluid droplet ejection cartridge containing at least one fluid to be dispensed. The fluid droplet ejection cartridge is attached to a translation mechanism for moving the fluid droplet ejection cartridge back and forth over a sample holder in an x direction. A sample tray translation mechanism is provided for moving a sample tray along a production path in a y direction orthogonal to the x direction through the two or more fluid droplet ejection devices.

The present invention relates to an internal fixing device for an apparatus in a transport mode, an apparatus comprising said device, and a method for reducing the risk of damage to the apparatus during transport. The internal fixing device comprises a limiting device, eccentric roller transmission assemblies, a motor assembly, a motion guide assembly, etc. The two ends of a motor output shaft are fixedly disposed on eccentric roller transmission assemblies on two sides of the apparatus. By triggering a microswitch on the limiting device, eccentric rollers and rocking handles form self locking in a transport mode to stop motion. The present invention can effectively reduce the risk of damage to the apparatus during transport.

A sample dilution method. The method comprises the following steps: moving from an initial workstation to a first workstation a ferrying unit bearing a first reactor containing a sample; distributing a diluent into the first reactor located at the first workstation; mixing the diluent and the sample in the first reactor to form a diluted sample; moving to a second workstation the ferrying unit bearing the first reactor containing the diluted sample, and distributing into at least two empty second reactors the diluted sample from the first reactor; moving to the first workstation the ferrying unit bearing all the second reactors containing a diluted sample, and distributing a reagent into the second reactors located at the first workstation; and mixing the reagent and the diluted sample in the second reactor.

An improved system and method for the selection and dispensing of reagents onto a target testing medium in an automated laboratory environment. The system utilizes multiple carousels rotatably-mounted upon a central turntable. The position of the central turntable, as well as the rotation of each carousel is controlled by a microprocessor-based control system. Multiple dispensers, each capable of storing and dispensing a particular reagent, are mounted about the circumference of each carousel. This configuration provides much higher reagent density than previously available. The testing medium is positioned at one or more loading stations. The control system directs the central turntable to a position from which a selected one of the carousels can be rotated so as to position a selected dispenser above the testing medium. The selected dispenser is then actuated to release a predetermined reagent onto the testing medium. The system can be configured so that multiple reagents can be dispensed, each from an associated dispenser, onto a single or multiple testing mediums. Each of these actuated dispensers being positioned over the targeted testing medium(s) positioned at one or more loading stations.
