Filtration recovery device and filtration recovery method

A filtration recovery method for removing cells from cell aggregates and collecting them by filtration, the method comprising:

• introducing a separation solution into a filtration recovery apparatus that comprises a filtration filter having a plurality of through-holes and a holder having an inlet port for introducing a liquid, an outlet port for discharging the liquid, and a flow path communicating the inlet port and the outlet port, wherein the filtration filter is arranged in the flow path between the inlet port and the outlet port of the holder to introduce the cell aggregate into the filtration recovery apparatus;
• detaching cells from the cell aggregate by keeping the cell aggregate immersed in the separation solution;
• capturing the cells with the filtration filter by discharging the separation solution from the filtration recovery apparatus;
• submerging the filtration recovery apparatus into a recovery liquid stored in a liquid storage container with one end side of the holder provided with the outlet port;
• introducing a liquid for recovery from the outlet port of the holder of the filtration recovery apparatus;
• blocking the outlet port of the holder of the filtration recovery apparatus;
• and
• collecting the cells together with the liquid held in the holder of the filtration collecting apparatus.

A filtration recovery method for filtering and recovering a liquid containing an object to be filtered, the method comprising:

• capturing the filtration object with a filtration filter that comprises a plurality of through-holes and a holder having an inlet port for introducing a liquid, an outlet port for discharging the liquid, and a flow path communicating the inlet port and the outlet port, wherein the filtration filter is arranged in the flow path between the inlet port and the outlet port of the holder, by introducing the liquid containing the object to be filtered into a filtration recovery device;
• submerging the filtration recovery device into a recovery liquid stored in a liquid storage container with one end side of the holder provided with the outlet port;
• introducing the recovery liquid from the outlet port of the holder of the filtration recovery device;
• blocking the outlet port of the holder of the filtration recovery device;
• and
• recovering the object to be filtered together with the recovery liquid held in the holder of the filtration recovery device.
