摘要:
An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, performing an analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material and for presenting the containers for machine access thereto, and a device for holding containers of reagents in a temperature controlled environment and presenting the containers for machine access thereto. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte. The process is performed by automatically moving each of a plurality of reaction receptacles containing a solid support material and a fluid sample between stations for incubating the contents of the reaction receptacle and for separating the target analyte bound to the solid support from the fluid sample. An amplification reagent is added to the separated analyte after the analyte separation step and before a final incubation step.

The invention is a laboratory mill that allows small samples to be shaken, mixed, ground, homogenized or comminuted effectively within a small vial. The design is similar to a planetary mill but unlike those devices, neither axis of rotation is centered on the axis of the processing vessel. The design allows many vials to be processed at one time and even when the diameter of the vial is quite small, maintains the processing performance. The performance of the device when used as a comminuter is demonstrated showing that the device can comminute organic solids down to a median particle size of 1 micrometer with a narrow size distribution. Because the processing takes place within a vial, the mill does not require cleaning between samples which allows the application of the device in automated or high throughput systems. Since the action occurs in one plane, vials are able to be retained by a stationary plate above the vials and additionally makes the device amenable to automation of sample loading and unloading.

The present invention provides an analysis tool that can achieve excellent stirring efficiency and can yield highly accurate and reliable analytical values. An analysis tool 1 for analyzing a component in a sample by reacting it with a reagent includes: the reagent, a magnetic material for stirring the sample and the reagent to mix them together; and a reagent arrangement portion 13. In the reagent arrangement portion 13, the reagent and the magnetic material are provided separately (the reagent parts 17 and the magnetic material part 18), and the magnetic material is fixed to the reagent arrangement portion 13 (the magnetic material part 18) with a water-soluble paste. As the water-soluble paste, it is possible to use carboxymethyl cellulose, for example. As the magnetic material, it is possible to use magnetic beads, for example.

摘要:
An analyzer for performing automated assay testing. The analyzer includes a storage and conveyor system for conveying cuvettes to an incubation or processing conveyor, a storage and selection system for test sample containers, a storage and selection system for reagent containers, sample and reagent aspirating and dispensing probes, a separation system for separating bound from unbound tracer or labeled reagent, a detection system and date collection/processing system. All of the subunits of the machine are controlled by a central processing unit to coordinate the activity of all of the subunits of the analyzer. The analyzer is specifically suited for performing heterogeneous binding assay protocols, particularly immunoassays.

A quality control device for a blood analyzer using whole blood, which specifically can be used to check the correct operation of the blood analyzer. The device includes a storage for storing control bloods by cooling; a mechanism for bringing the control bloods back to the temperature specified by the control blood manufacturer; a stirring mechanism used for resuspension of the cells; and a mechanism for sampling the blood thus prepared.
摘要:
Rapid mixing and homogenisation of reaction mixtures with respect to temperature and chemical concentrations, as well as greatly enhanced mass transport is achieved when the reaction mixture placed in a vassel suitable for centrifugation, and subjected to asymmetric heating, cooling and simultaneous centrifugation at conditions for creating an enhanced flow within the reaction mixture, wherein the flow ensures practically total mixing and homogenisation of the reaction mixture.
