CELL CULTURE SOLUTION RECOVERY FILTER UNIT, CELL CULTURE SOLUTION RECOVERY METHOD, AND CELL CULTURE SOLUTION RECOVERY KIT

摘要

To provide a cell culture solution recovery filter unit that suppresses variation in a survival rate of cells, and is capable of shortening recovery time of cell culture solution.SOLUTION: A cell culture solution recovery filter unit comprises: a metal porous membrane (2) which filters cells contained in cell culture solution; a holding member (3) which holds an outer peripheral part (2A) of the metal porous membrane; and a tubular member (4) which is connected to the holding member such that a hollow portion (4b), which is a flow channel of the cell culture solution, opposes at least a part of principal surface of the metal porous membrane, in which an annular protrusion part (32d) protruding in a thickness direction of the holding member is provided on a principal surface of a separating side of the tubular member of the holding member, the tubular member is equipped with a fitting part (4a) capable of being fitted with the protrusion part, and by allowing the fitting part to fit with an outer peripheral surface of the protrusion part, the tubular member can be attached to the holding member freely detachably.SELECTED DRAWING: Figure 4
