The utility model relates to a device for researching zooplankton, concretely speaking, it is a medium and large zooplankton counting and classification batch scanning loading device. the main body of the device is a hollow structure, on which several through holes are opened, the injection device is connected with one through hole when injecting the water sample to be detected into the device main body, At least one of the remaining through holes in the apparatus main body is provided with a filter device, air bubbles injected into the main body of the water sample to be measured are discharged through the filtering device, except through holes communicated with the injecting device and through holes for installing the filtering device, the through holes communicated with the injecting device and the filtering device are blocked through the blocking devices, and the blocking devices are respectively installed on the through holes communicated with the injecting device and the filtering device after the water sample to be measured is injected; The main body of the device after injecting the water sample to be measured is placed on the scanning surface of the scanner, and the upward surface of the main body of the device is covered with the back plate device during scanning. The utility model has the advantages of simple assembly, can be used at any time, small and convenient, the operation is simple, the cost is low.
