Abstract: A filtration filter is suitable for performing cross-flow filtration by using a metallic porous membrane. A metallic porous membrane has a membrane portion for filtering filtration objects contained in a fluid and a held portion provided at its outer periphery. A first frame member and a second frame member hold the held portion of the metallic porous membrane there between. The held portion has a bent portion bent to a second principal surface side opposing a first principal surface of the membrane portion. The first frame member is in contact with the held portion at the first principal surface side of the metallic porous membrane. The second frame member is disposed at an inner side portion of the first frame member and is in contact with the held portion at the second principal surface side of the metallic porous membrane.

Abstract: A cell filtration filter that includes a metal membrane part that has a first main surface on which the cells are to be captured and a second main surface that opposes the first main surface. The metal membrane part has a plurality of hole edges that define a plurality of first through holes and a support region that is arranged around the hole edges and supports the hole edges. In the support region of the metal membrane part, a plurality of second through holes, which have smaller openings than the first through holes, are arranged so as to surround the hole edges. On the first main surface of the membrane part, the hole edges are raised with respect to the support region.

Abstract: A filtration filter device that enables the sealability of a fluid channel to be improved is provided. A filtration filter device according to the present invention includes a first channel-forming member that has a first channel through which a fluid flows inside thereof, a second channel-forming member that has a second channel through which a fluid flows inside thereof, and a filtration filter that extends across the first channel or the second channel and that filters an object to be filtered that the fluid contains. The first channel-forming member includes an external thread. The second channel-forming member includes an internal thread. The first channel-forming member and the second channel-forming member have respective inclined surfaces that incline with respect to a screw direction in which the external thread is screwed into the internal thread at positions nearer than the external thread and the internal thread to the first channel or the second channel, and the inclined surfaces are in contact with each other with the external thread screwed in the internal thread such that the first channel and the second channel are in communication with each other.

Abstract: A filtration device includes a container, a channel member, and a filter. The container has a space of variable volume that contains a liquid, the liquid including a target substance to be separated by filtration. The channel member includes a channel and an opening that are defined therein, the opening being provided at a position along the channel in a direction transverse to the direction in which the channel extends. The channel member has an attachment part to which the container is attached and which provides communication between the space in the container and the channel. The filter is attached inside the channel member and positioned at the opening.

Abstract: A measurement method measures an amount of substance of an analyte in a sample fluid passing through a perforated structure having a pair of principal surfaces opposed to each other and having a plurality of cavity portions extending through both of the principal surfaces. An elapsed time from a time when the sample fluid begins passing through the perforated structure or a predetermined time thereafter to a time when a characteristic value of the perforated structure reaches a predetermined threshold. The elapsed time is used to determine the amount (the concentration) of substance of the analyte.

Abstract: A void-arranged structure that includes a pair of principal surfaces opposing each other and a plurality of void sections that penetrate through the pair of principal surfaces. The void-arranged structure is configured of a plurality of unit structures each of which includes a first void section and a second void section having a different shape from a shape of the first void section, and the overall shape of the unit structure, when the principal surface is viewed from above, is not mirror-symmetric with respect to a predetermined imaginary plane orthogonal to the principal surface of the void-arranged structure.

Abstract: A metal mesh has a plurality of through-holes. A photosensitive organic material is attached to at least part of the metal mesh. The metal mesh is sterilized and/or cleaned. A determination of whether or not the sterilization and/or cleaning has been successful is made by analyzing the photosensitive organic material attached to the metal mesh.

Abstract: A filter for filtering nucleated cells that includes a body containing at least either a metal or a metal oxide as its main component; and plural through holes, each of which have a shape other than a square shape, formed therein. A longitudinal diameter of an inscribed ellipse within each of the through holes is smaller than a size of a nucleus of each of the nucleated cells to be filtered. The inscribed ellipse of the through hole is an ellipse that abuts all sides that define an opening of the through hole.
