1. Device for compressing a hydrogel, comprising
a separate graft frame (500) comprising a circumferential frame member (502) and a membrane bottom (501) connected to said frame member (502), wherein the graft frame (500) is designed to receive said hydrogel (H) so that a hydrogel layer (H) is formed covering said membrane bottom (501), a guiding frame (100) having a plurality of guiding rods (104) extending along a compression direction (C), a filter plate (300), a first component (200) comprising a base (201) having a plurality of openings (204), particularly formed in an edge region (202) of said base (201), wherein each opening (204) is associated to one of the guiding rods (104), wherein the first component (200) is designed to be arranged on the guiding frame (100) in an operating mode of the device such that each guiding rod (104) extends through its associated opening (204), wherein the first component (200) further comprises a circumferential wall (203) protruding from said base (201) of the first component (200), so that the first component (200) forms a container (220) that is designed to receive the filter plate (300) and the graft frame (500) in said operating mode so that the filter plate (300) is arranged between a bottom (230) of said container (220) and the membrane bottom (501) of the graft frame (500), a second component (400) comprising a base (401) having a plurality of openings (404), particularly formed in an edge region (403) of said base (401) of the second component (400), wherein each opening (404) is associated to one of the guiding rods (104), wherein the second component (400) is designed to be arranged on said first component (200) in said operating mode, such that each guiding rod (104) that extends through its associated opening (204) of the first component (200) is also inserted into its associated opening (404) of the second component (400) so that the second component is guided by said rods (104) along the compression direction (C), a separate piston (600) that is designed to be connected to said second component (400) in a releasable manner in said operating mode of the device, particularly by means of a latching connection, wherein in said operating mode the second component (400) is designed to press the piston (600) along the compression direction (C) against said hydrogel layer (H) residing on the membrane bottom (501) of the graft frame (500) so as to compress the hydrogel layer (H) between the piston (600) and the membrane bottom (501). |
