Liquid samples containing for example differerent combinations of DNA and markers are subjected to various processing steps, for examle exposure to different temperature baths. A flexible band is used that contains a series of cavities arranged along a longitudinal direction of the flexible band. The liquid samples are inserted into the cavities and the band is subsequently fed through a succession of processing stations. The band extends through the stations when the processing steps of the stations are applied. By advancing the band the samples are subjected to successive processing stages. At the end of the process the band may be disposed of, for eexample after extracting the samples.

An automated system and process is provided for pooling samples from a multiplicity of blood or plasma donations for subsequent testing to uniquely identify any such blood or plasma donations which may be infected with a particular virus. The system includes an autosampler needle which is directly inserted into a blood or plasma sample aliquot container in order to withdraw an aliquot portion of the contents for forming a sample pool with aliquot portions of other blood or plasma samples. The autosampler comprises a tubular piercing member having a hollow interior bore and a tubular shroud surrounding the piercing member.

A flexible plastic cuvette belt comprises a series of open-topped chambers defining said cuvettes interconnected by webs. The chambers are generally rectangular in cross-section with their side faces having an approximately flat profile across their widths. The belt is used in conjunction with a photometric analysis station of the clinical analyzer which has a pair of spaced parallel plates which engage the cuvette side faces and render or keep them parallel. The forming press for use in the manufacture of such a cuvette belt is also disclosed.

The cover film sticking device is capable of securely sticking cover film pieces on specimen samples on all slide glasses stored in a basket, which starts to stick the cover film pieces formed, by cutting off long cover film unwound from a film roll to a specified length on the specimen samples on the plurality of slide glasses stored in the basket 26 taken out from a load tank 12 filled with a volatile protective solution. The sticking device is characterized by cover film length securing means for unwinding the long cover film from the film roll and extending the same until reaching cutting means so as to secure the cover film of such a length that can form the cover film pieces to be stuck onto the specimen samples on the maximum number of the slide glasses storable in the basket 26 taken out from the load tank 12.
摘要:
The invention relates to a method for testing the interaction between at least one liquid sample and a respective solid sample. The method comprises at least the steps of—providing adjacent first and second cavities, where said first and second cavities are in mutual communication via at least one passage, —placing the solid sample in said first cavity, —introducing the liquid sample in one of said first and second cavities, —sealing at least said first and second cavities from the exterior, so as to form a closed system of communicating cavities, —bringing said liquid sample into contact with the solid sample in said first cavity, transferring substantially all of said liquid sample to the second cavity after it has been brought into contact with the solid sample, —and testing the desired properties of any one or both of said liquid sample or said solid sample.
摘要:
An automatic analysis apparatus of small size which meets the needs of regional hospitals or medium- or small-sized hospitals, and which is easy to handle and simple in construction. The apparatus employs reaction vessels of the disposable type so as to substantially completely prevent a problem of cross contamination while enabling a low running cost. The automatic analysis apparatus has a transfer path for transferring and guiding reaction vessels one by one in a linear manner, a reaction vessel transfer device for successively transferring the reaction vessels to a specimen discharging position, a reagent discharging position, an optical measuring position and a reaction vessel disposal position with respective predetermined timings, a specimen discharging device adapted to discharge a predetermined amount of a specimen to the reaction vessels at a specimen discharging position, a reagent discharging device adapted to discharge a predetermined amount of a reagent corresponding to a specimen being analyzed at a reagent discharging position, a stirring device for stirring a liquid in each of the reaction vessels, an optical measuring device for optically measuring the liquid in each reaction vessel, a disposal device adapted to discard, without cleaning, the reaction vessels the optical measurements on which are finished, and a central device for analyzing the data obtained by the optical measuring device.
