[Object] A target cell capture filter is provided, having an improved capture ratio per unit area, structured as a filter for extracting and capturing target cells contained in a biological sample such as blood or the like in a simple manner, in a short period of time, and with high efficiency.

[Solving Means] A target cell capture filter is structured to have a capture face for capturing target cells in a liquid. The target cell capture filter has multiple notches that allows a part of the capture face to be elastically deformed in a direction that is orthogonal to the capture face, thereby providing gaps. At least part of the plurality of notches are a first notch group including multiple notches designed such that there is a difference between the notches in a shortest distance from a greatest deformation location of the notch to an outer edge of the capture face, and such that the same elastic deformation amount is exhibited with respect to the impulse per unit area.

A disclosed screening apparatus includes a subgrid, and a screen element attached to the subgrid via laser welding at a plurality of attachment positions such that, under vibrational excitation, the screen element has a pre-determined profile of vibrational motion relative to the subgrid. The screen element may be attached at a maximal number of attachment locations to the subgrid to minimize relative motion of the screen element and the subgrid under vibrational excitation, or the screen element may be attached a sub-set of the maximal number of attachment locations to allow vibrational motion of the screen element relative to the subgrid. A disclosed method may include attaching a plurality of screen elements to a respective plurality of subgrids, attaching the plurality of subgrids to one another to form a screening pre-assembly, and cutting edges of the screening pre-assembly to form the screen assembly having a perimeter with a pre-determined shape.

A screen filter for wastewater applications includes a chain tensioning system. The chain tensioning system provides a tensioning force for a screen filter chain. The chain tensioning system includes a chain adjuster device configured to tension the screen filter chain. The chain tensioning system additionally includes a sensor configured to provide a signal representative of a load applied by the chain adjuster; wherein the chain adjuster device is configured to apply a force in a direction that tensions the chain and wherein the signal provided by the sensor is representative of the force.

At least one infrared element arrangement having at least one infrared element (3) comprising a plurality of infrared radiators (4) is mounted on a frame moveable with respect to a synthetic filter fabric mounted to a filtering surface. The frame may have wheels or the like such that the infrared radiators may be moved along the length of the filtering surface to heat the synthetic filter fabric (6) to a temperature of 100 to 160° C. for shrinking the fabric (6) on the filtering surface (5).

A method and/or a system filters particles using a screen with modular segments installed into a frame. The frame has a perimeter structure and an orthogonal array of support members. The segments have a segment perimeter frame, an orthogonal array of ribs and a mesh stretched across the segment. When the mesh of the segments is damaged, the damaged segment is removed from the frame and a replacement segment is installed.

Provided is a filter-attached cartridge which is inexpensive and has high productivity. This filter-attached cartridge has: a first resin mesh which is an integrally molded body having a plurality of ribs arranged therein in a lattice shape; and a cylinder formed in a cylindrical shape so as to surround the first mesh.
