A filter that includes: a filter base portion having a first main surface and a second main surface, the filter base portion defining a plurality of through-holes connecting the first main surface and the second main surface via an inner wall extending from the second main surface toward the first main surface; and a support portion that has a plurality of protruding portions located in respective through-holes of the plurality of through-holes and disposed on the second main surface of the filter base portion, the plurality of protruding portions having an outer wall in contact with the inner wall of the filter base portion, wherein a first opening on the first main surface side of the filter base portion is larger than a second opening on the second main surface side of the filter base portion, and there is a clearance between the filter base portion and the support portion.

Filter

A filtration filter that includes a filter section having a plurality of through-holes passing through a first main surface and constructed such that objects to be filtered contained in a liquid are captured and a second main surface opposite the first main surface; and a frame section surrounding an outer periphery of the filter section, wherein a first film thickness at a center of the filter section is larger than a second film thickness of the filter section at a position closer to the frame section than the center of the filter section.

Filtration filter and filtration device

Cell filter

A filter includes a plurality of first through holes which are periodically formed. At least one of the plurality of first through holes is divided by a plurality of second through holes that are smaller than the first through holes. With such a configuration, the cell aggregate having the desired size can be easily sampled.

Planar filtering device with differently sized through holes

A filtration recovery device according to the present disclosure may include: a filtration filter having a plurality of through-holes; and a holder having an introduction port configured to introduce a liquid, a discharge port configured to discharge the liquid, and a flow path configured to communicate the introduction port and the discharge port with each other, in which the filtration filter is disposed in the flow path between the introduction port and the discharge port of the holder.

Filtration recovery device and filtration recovery method

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. An arithmetic average roughness of a first side of the filter part is smaller than a size of a nucleus of the nucleated cells to be filtered.

A filtration filter according to the present invention includes a surface layer composed mainly of Pd, a base material inside the surface layer and composed mainly of a PdNi alloy, and an intermediate layer between the surface layer and the base material, wherein the intermediate layer is composed mainly of a PdNi alloy in which a Pd:Ni ratio changes from a surface layer side toward a base material side.

Filtration filter

A filtration filter having a tubular shape, defining a first opening and a second opening facing the first opening, and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction from the first opening of the filtration filter toward the second opening and extends in a second direction along at least a first portion of a circumference of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

A filtration filter having a filter substrate defining a plurality of through-holes extending from a first principal surface to a second principal surface opposite the first principal surface; and a pair of projections between adjacent through-holes of the plurality of through-holes, the pair of projections being on corresponding end portions on opposite sides in a width direction of the filter substrate and protruding from the first principal surface so as to define a reservoir part with the first principal surface.

Filtration filter and filtration method

A separation recovery system for separating and recovering an object to be separated includes a metal porous membrane which has a first principal surface and a second principal surface facing the first principal surface and has a plurality of through-holes extending between the first principal surface and the second principal surface, a supply device which supplies a first fluid containing the object to be separated from the first principal surface of the metal porous membrane toward the second principal surface, and a backwash device which supplies a second fluid containing a plurality of particles larger than a size of the plurality of through-holes of the metal porous membrane in a direction from the second principal surface of the metal porous membrane toward the first principal surface.

Separation recovery system and separation recovery method

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.

Filtration device and filtration method

A liquid cell culture medium collecting filter unit includes a porous metal membrane that filters out cells in a liquid cell culture medium, a support that holds a peripheral portion of the porous metal membrane. and a tubular member that has a hollow part serving a flow path for a liquid cell culture medium. The tubular member is connected to the support such that the flow path faces at least part of a main surface of the porous metal membrane.

Filter unit for filtering and method for collecting cells in a liquid cell culture medium

A filtration device includes a first channel member, a second channel member, and a filter. The first channel member has a recess recessed inward from an outer wall surface. A groove is formed is the recess and has an opening in a recessed surface of the recess. First and second channels, each defined by a through-hole, are formed in the first channel member and are connected to the groove. A first connection part connects the groove with the first channel. The second channel member has a projection that detachably mates with the recess. The second channel member includes a discharge channel that has an opening in a projecting surface of the projection, the opening being located over the groove. The filter is disposed along the groove, and positioned at the opening of the discharge channel. When the first and second channel members are placed in a operative relationship, a third channel is formed by the projecting surface of the projection and the opening of the groove. The third channel is connected to the first channel via the first connection part. The third channel at which the filter is positioned has a smaller cross-sectional area than the first channel.
