Cell culture wafers and cell culture apparatus

Abstract

The present invention aims to provide a cell culture wafer that prevents air bubbles from being trapped in the wafer and reduces the deviation in the flow velocity distribution along the width of the flow path in a curved flow path for uniform cell seeding. The cell culture wafer (1) according to an embodiment of the present invention is: a cell culture wafer (1) comprising a stack (100, 200) having a flow path structure internally; the stack (100, 200) comprising a flow path substrate (L2, L4) having flow paths (F2, F4) leading to ports (P1, P2, P3, P4); the flow paths (P1, P2, P3, P4) comprising: a curved flow path (FC), which, in a top view of the flow path substrate (L2, L4), is formed in a curved shape. Furthermore, it has a gradually changing cross-sectional area in the direction of fluid flow; and a first connecting flow path (FJ1) connects the aforementioned port to the aforementioned curved flow path (FC), and has a fixed cross-sectional area in the direction of fluid flow; the cross-sectional area of ​​the aforementioned first connecting flow path (FJ1) is smaller than the minimum of the cross-sectional areas of the aforementioned ports (P1, P2, P3, P4) and the cross-sectional area of ​​the aforementioned curved flow path (FC); in the aforementioned top view, the flow path width of the aforementioned curved flow path (FC) gradually changes in the direction of fluid flow.
