Summary:To provide a concentrating device that concentrates biological particles easily, quickly and efficiently.SOLUTION: A concentrating device 10 for biological particles 50 includes: a housing 20 in which a liquid 40 to be treated containing the biological particles 50 and water is injected from an inlet 21 and discharged from an outlet 22 due to the differential pressure between the inlet 21 and the outlet 22; a concentrating membrane 30 placed to separate the inlet 21 and the outlet 22, which is a hydrophilic porous membrane that does not adsorb the biological particles 50, and that allows discharged liquid 42, which is a liquid obtained by reducing the concentration of the biological particles 50 from the liquid to be treated 40, to permeate from the surface on the inlet 21 side to the surface on the outlet 22 side; a concentrating space 24 that houses a concentrated liquid 41 in which the concentration of the biological particles 50 is increased by the concentrating membrane 30 on the upstream side of the concentrating membrane 30 in the housing 20; and a support portion located between the concentrating membrane 30 and the outlet 22 where the concentrating membrane 30 is placed and a drainage groove 20E which is a plurality of radial grooves communicating with the outlet 22 is provided.SELECTED DRAWING: Figure 3 【課題】生物学的粒子を簡易に迅速に効率よく濃縮する濃縮デバイスを提供する。【解決手段】入口２１と出口２２との差圧により生物学的粒子５０及び水を含む被処理液４０が入口２１から注入されて出口２２から排出されるようになっているハウジング２０と、入口２１と出口２２とを隔てるように設けられ、生物学的粒子５０が吸着しない親水性の多孔膜であり、入口２１側の面から出口２２側の面に、被処理液４０から生物学的粒子５０の濃度を減じた液体である排出液４２を透過させる濃縮膜３０と、ハウジング２０内における濃縮膜３０の上流側で濃縮膜３０により生物学的粒子５０の濃度を増した濃縮液４１を収容する濃縮空間部２４と、濃縮膜３０と出口２２との間に位置し、濃縮膜３０が載置されるとともに、出口２２と連絡する複数の放射状の溝である排液溝２０Ｅが設けられている支持部と、を備えた、生物学的粒子５０の濃縮デバイス１０。【選択図】図３
