PROBLEM TO BE SOLVED: To provide a cell separation device which can easily stratify without disarranging the interface of sample on stratification, and can prevent the mixing of a separated target substance to recover the target substance in good purity.SOLUTION: The cell separation device has the first container 11 having the first liquid-receiving portion 51, the second container 12 having the second liquid-receiving portion 52 and disposed under the first container 11, and a communication member 20 disposed between the first container 11 and the second container 12 and having the first needle 72 extended toward the first liquid-receiving portion 51 and the second needle 73 communicating with the first needle 72 and extended toward the second liquid-receiving portion 52. The cell separation device further has a switch mechanism 55 which can switch into a communication state for communicating the first liquid-receiving portion 51 with the second liquid-receiving portion 52 through the communication member 20 or into an interception state for intercepting the communication, by the approach of the first container 11 to the second container 12 or the separation of the first container 11 from the second container 12. |
