Provided is an automatic analysis device provided with a scattering optical system which enables a reduction in a reaction solution required for analysis by installing a light source at an angle with respect to a plane of a reaction container and enables a reduction in the running cost of a reagent, and a relatively free design with respect to the size and shape of the reaction container. An automatic analysis device is provided with a reaction container in which a sample and a reagent react with each other, a reaction disk in which the reaction containers are disposed in a line on the circumference thereof, a reaction disk rotation mechanism which rotates the reaction disk, a light source which irradiates the reaction container with measurement light, and a detector which detects light emitted from the light source and transmitted through a reaction solution in the reaction container, the automatic analysis device being provided with an optical system which causes the light from the light source to be incident on the reaction container at a predetermined angle with respect to a plane of the reaction container.

Automatic analysis device

An automatic sample analyzer includes: a pipette, a pipette driving device which moves the pipette to a sample vessel present in a predetermined position to cause the pipette to suck up a sample from the sample vessel, and then moves the pipette to an open vessel provided in another predetermined position to cause the pipette to discharge the sample into the open vessel, and an analyzing section for analyzing the discharged sample, the pipette driving device comprising a vertically movable main arm and an elongated guide arm cantilevered by the main arm and extending horizontally, the guide arm having a smaller flexural rigidity than the main arm, wherein the main arm vertically moves the pipette when the sample is to be sucked up from the sample vessel, and the guide arm guides the pipette to the open vessel and then vertically moves the pipette when the sample is to be discharged into the open vessel.

Automatic sample analyzer and its components

A mixing vial is provided for an automated biological reaction apparatus typically used for staining tissue samples in Immuno-histological and in-situ hybridisation reactions. The mixing vial allows reagents placed on the apparatus to be mixed together to form additional or blended reagents. A reagent dispenser mounted on a robotic arm withdraws reagent from the reagent containers and deposits it into one of the mixing vials. Several reagents can be deposited into each vial. Mixing is undertaken by withdrawing the reagents in a vial and re-dispensing the reagent back into the vial. Mixing may take place between the operation of other tasks performed by the apparatus, and a scheduler is used to ensure blended reagent is provided before it is required in one of the processes undertaken on the apparatus. The apparatus is able to automatically identify which blended reagents are required and when they must be applied to provide an appropriate schedule that minimises time taken to stain samples.

Method and apparatus for fluid dispensation, preparation and dilution

A process for prioritizing urgent test tubes in a test tubes (50) transport installation is disclosed, the test tubes (50) being loaded on transport devices (4) of single test tubes (50) in an automated analysis laboratory, comprising the loading of test tubes (50) classified as urgent and non urgent on transport devices (4) for transporting single test tubes (50), moving said loaded transport devices (4) on a conveyor belt until they interact with an identification device (5) identifying the test tube upstream of processing modules (6) of the test tubes (50), removal of the test tubes (50) that are recognized to be non-urgent from the respective transport device (4) and discharging of the non-urgent test tubes (50) onto a wait bench (10) for non- urgent test tubes (50), moving transport devices (4) for transporting single urgent test tubes (50) towards the processing modules (6), the recall by a control unit (7) of the non-urgent test tubes (50) at the moment in which the availability of the processing modules (6) for non-urgent the test tubes (50) occurs and the consequent loading of the non-urgent test tubes (50) on the bench (10) onto transport devices (4) of the installation, the bench (10) providing means for locating the non-urgent waiting test tubes (50).

Process for managing urgent samples in an automation installation

A method for testing a biological sample is proposed, wherein the sample is divided into a plurality of sample portions, is fed to a sensor arrangement in a first conveying direction and is carried away in a second conveying direction which is opposite to the first conveying direction, and/or a sensor cover is lowered onto a sensor apparatus multiple times. Furthermore, a cartridge for testing a biological sample is proposed, wherein different fluidic circuits can be formed by actuating valves in the cartridge, and the sample or another fluid can be conveyed in the fluidic circuits by means of a pump apparatus.

Analysis system and method for testing a sample

The present invention relates to the preparation of povidone-iodine ointment which is composed of povidone-iodine 10%, potassium iodate 0.2-0.25%, octadecanol 8.1-9%, cetanol 5.4-6%, stearin 9-10%, sodium louryl sulfate 3-3.5%, glycerin 13.5-15% and pure water 46.25-50.8%. The providone-iodine is dissolved in pure water and heated to 60-70 deg.C. The ointment if formed by adding water with same temperature, stirring to form aqueous phase, them mixing oil phase with same temperature, and stirring and emulsifying the admixture again. It can be used to treat bacterial, virus fungus dermatosis.
