LIQUID CELL CULTURE MEDIUM RECOVERING FILTER UNIT, LIQUID CELL CULTURE MEDIUM RECOVERING METHOD, AND LIQUID CELL CULTURE MEDIUM RECOVERING KIT

摘要

Provided is a liquid cell culture medium collecting filter unit that can reduce variations in the proportion of remaining cells and can shorten the time required to collect a liquid cell culture medium. A liquid cell culture medium collecting filter unit (1) according to the present invention includes a porous metal membrane (2) that filters out cells in a liquid cell culture medium; a holding member (3) that holds a peripheral portion (2A) of the porous metal membrane (2); and a tubular member (4) that has a hollow part (4b) serving a flow path for the liquid cell culture medium and is connected to the holding member (3) such that the hollow part (4b) faces at least part of a main surface of the porous metal membrane (2).
