A connecting channel 3 is provided between the compartments 2 to connect the compartments 2, so that the liquid injected into the container 1 can communicate with each other through the connecting channel 3, so that the corresponding number of compartments 2 form a communicating vessel, which facilitates the rapid flow of the liquid injected into the container 1 into the corresponding compartments 2 for distribution. The connecting channel 3 is provided with a first on-off structure for closing or opening the connecting channel 3. After the container 1 has distributed the liquid, the connecting channel 3 between the compartments can be closed by the first on-off structure, so that each cavity 2 becomes an isolated cavity. A drain port 4 is provided at the bottom of each corresponding compartment 2, and the drain port 4 is provided with a second on-off structure for opening or closing the drain port 4. The drain port 4 can be controlled by the second on-off structure to discharge the liquid in the corresponding isolated compartment 2 and inject it into the subsequent culture container of the corresponding application.
