SELECTOR

To provide a selector capable of efficiently removing unnecessary cells from an aggregation of biological samples.SOLUTION: A selector has: a device body which stores dispersion liquid containing a plurality of biological samples; a detection part which detects at least any one of a shape and a motion state of the biological samples; a discharge part which discharges the biological samples from the device body; and a control part which drives the discharge part on the basis of a previously stored determination reference and a detection result of the biological samples in the detection part. The device body has; a storage part which stores dispersion liquid; and a discharge port which is connected to the storage part and discharges the biological samples from the storage part. The discharge part is provided at the discharge port, and the control part determines pass/fail of the biological samples detected by the detection part on the basis of the determination reference and the detection result and discharges the biological samples determined to be defect from the device body.SELECTED DRAWING: Figure 1 【課題】生体試料の集合から、不要な細胞を効率的に除去することが可能な選別装置を提供する。【解決手段】生体試料を複数含む分散液を貯留する装置本体と、生体試料の形状および運動状態の少なくともいずれか一方を検出する検出部と、装置本体から生体試料を排出する排出部と、予め記憶された判断基準と、検出部における生体試料の検出結果とに基づいて、排出部を駆動する制御部と、を有し、装置本体は、分散液を貯留する貯留部と、貯留部に接続し、貯留部から生体試料を排出する排出口と、を有し、排出部は、排出口に設けられ、制御部は、判断基準と検出結果とに基づいて検出部で検出された生体試料の良否を判断するとともに、不良と判断された生体試料を装置本体から排出させる選別装置。【選択図】図１
