PERMEABLE MEMBRANE SUPPORT

A permeable membrane support having a removable permeable membrane is disclosed The permeable membrane support includes a lower support having a hollow cylinder shape with an outer diameter smaller than an inner diameter of a plate well so to be accommodated in the plate well, wherein the lower support includes: an upper end having a first opening and a lower end having a second opening; an inner wall extending between the upper and lower ends and having an open channel defined therein and extending therebetween and communicating with the first and the second openings; a support surface portion extending inwardly from an inner surface of a lower end of the inner wall and having a central opening defined therein constituting the open channel; an upper support including: a cylindrical lower member constructed to be partially accommodated in the lower support; a pair of opposing wings constructed to be supported on a top of the plate well; and a deformable beam portion extending upwardly from an upper circumferential end of the cylindrical lower member to the two opposing wings so as to connect the two opposing wings and the cylindrical lower member to each other; and a permeable membrane disposed between the support surface portion of the lower support and a bottom surface of the cylindrical lower member of the upper support, wherein the permeable membrane includes a porous thin-film and a sealing pattern bonded to a circumference of the porous thin-film, wherein the inner wall of the lower support and the deformable beam portion of the upper support include a hook and a groove, respectively, or include a groove and a hook, respectively, for snap-fit coupling between the lower and upper supports.
