  • Patent number: 11187631
    Abstract: A device for capturing biological particles in suspension in a liquid medium. The device includes a container that is open via a lower opening, and a filter membrane fixed on the container in such a way as to close the lower opening. Inside the container are: a buffer made of a porous foam and having a planar face resting on the filter membrane, an absorbent block resting on the buffer and able to absorb the liquid medium when it is in contact with the liquid medium, and a spring designed to impede the expansion and/or movement of the absorbent block away from the lower opening of the container. Also, methods for capturing biological particles in suspension in a liquid medium using a capture device, and preparation a sample intended for biological analysis. Further an analysis apparatus that has a capture device.

  • Patent number: 8992861
    Abstract: A device for capturing suspended bioparticles in a liquid medium, includes: a tube (101) including first and second ends, the first end of the tube being closed by the surface of a filter membrane (102) rendered stationary by adhesion onto the cross-section of the walls of the tube, a piston (104) including a rod (107) connected to a bearing element (108), the rod sliding along an axis parallel to the wall of the tube (101), and a block (103) of hydrophilic absorbent material placed inside the tube (101), inserted between (i) the inner surface of the filter membrane (102) and (ii) the piston (104) bearing element (108).
