FIELD: medical diagnostics.
SUBSTANCE: invention relates to the analysis of biological preparations for medical diagnostics. A device for capturing biological particles suspended in a liquid medium, wherein the device has: a container opened through the lower opening; a filter membrane attached to the container so as to cover the lower opening; and inside the container: a buffer made of porous foam and having a flat surface supported by a filter membrane; an absorbent block supported by a buffer and capable of absorbing the specified liquid medium when in contact with the specified liquid medium; and an elastic element designed to prevent the expansion and/or movement of the absorbent block away from the lower opening of the container.
EFFECT: improved reliability of cell capture.
