Provided is a composition for mononuclear cell-containing plasma separation capable of suppressing a flow of the composition for mononuclear cell-containing plasma separation during storage, capable of satisfactorily forming a partition during centrifugation, and capable of yielding mononuclear cell-containing plasma with little admixture of blood cell components other than mononuclear cells. The composition for mononuclear cell-containing plasma separation according to the present invention contains an organic component having fluidity at 25° C. and two or more kinds of inorganic fine powders, and has a specific gravity of 1.060 or more and 1.080 or less at 25° C.

A sample vessel includes a biological sample container and a sample stabilizer container. The biological sample container is configured to receive a biological sample and to store the biological sample. The sample stabilizer container is configured to contain a stabilizer associated with the biological sample. The sample stabilizer container is assembled from a stabilizer vial, an adaptor, and a fluid channel. The stabilizer vial is configured to store an amount of the stabilizer. The adaptor is configured to secure the biological sample container and the stabilizer vial such that the biological sample container and the stabilizer vial form the sample vessel. The fluid channel extends through the adaptor from the stabilizer vial to the biological sample container, the biological sample moving from the biological sample container into the stabilizer vial through the fluid channel.

An analysis unit formed by an analysis body housing an analysis chamber and having a sample inlet and a supply channel configured to fluidically connect the sample inlet to the analysis chamber. Dried assay reagents are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilized mass formed by excipients and by assay-specific reagents.

The present invention provides a sample tube for polymerase chain reaction. The sample tube includes a sample tube body having an annular side wall and a bottom wall connected to annular side wall, wherein the annular side wall and the bottom wall form an accommodating space for accommodating a reaction mixture; and a first extension member extending from the bottom wall to the accommodating space, wherein, to carry out PCR, the reaction mixture immerses the first extension member, such that the light from the light source enters into the reaction mixture via the bottom and the bottom wall of the sample tube and the first extension member sequentially.

A laboratory automation system for processing sample containers containing laboratory samples and/or for processing the samples is presented. The laboratory automation system comprises a digital camera configured to take an image of the sample container together with a calibration element. The image comprises image data related to the sample container and image data related to the calibration element. The laboratory automation system also comprises an image processing device configured to determine geometrical properties of the sample container depending on the image data related to the sample container and the image data related to the calibration element.

A method of mass spectrometry is disclosed comprising focusing electromagnetic radiation into a region of a liquid sample 3 below a surface of the liquid sample so as to generate one or more bubbles 4. The one or more bubbles 4 rise to the surface of the liquid whereupon one or more droplets of liquid 6 are emitted from the surface of the liquid sample. The method further comprises directing the one or more emitted droplets 6 towards an inlet of a mass spectrometer 8.

The centrifuge tube includes: a tube body comprising an inner surface and an outer surface, a sensor provided at the inner surface of the tube body and comprising a first electrode group; and a second electrode group provided at the outer surface of the tube body and electrically connected with the first electrode group.

There are provided a blood examination kit with which the procedure carried out by an examination subject is simplified and a method of separating plasma or serum. The blood examination kit includes a blood collection instrument including a diluent and a first container that has an opening formed on one end side and accommodates the diluent; an absorption instrument including a first lid portion member that is arranged on one end side and can seal the opening of the first container, and an absorption member that is arranged on the other end side and absorbs a blood sample; and a separation and sealing instrument including a filtration member that separates plasma or serum from the blood sample diluted with the diluent, a second container that holds the filtration member on the other end side, accommodates the separated plasma or serum, and can be inserted into the first container, a second lid portion member that is arranged on one end side of the second container and can seal the opening of the first container, and a valve member that closes a flow channel between the first container and the second container.

A microtube comprises a sample receptor, a lid and a strip storage storing a chromatography strip. The chromatography strip is stored in a hollow part of the strip storage. The hollow part of the strip storage and an inner space of the sample receptor may be communicated in a closed condition under a state where the sample receptor and the lid are engaged.

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.
