The invention discloses an operating table for a liquid-based thin-layer cell pelleter. The operating table comprises a working box, a first experiment cabinet, a second experiment cabinet and a thirdexperiment cabinet are arranged on the inner side of the working box, the first experiment cabinet and the third experiment cabinet are located on the left side and the right side of the second experiment cabinet, the pelleter is arranged on the inner side of the first experiment cabinet, and a centrifugal machine is arranged on the inner side of the second experiment cabinet. By arranging a water bath box, a heating piece, a temperature sensor, a water pipe, a water pump and a water tank, a stock solution can be stored in a constant-temperature environment in a heat preservation box, and thesituation that cells are changed due to the change of the environment temperature, and smear is affected is prevented; and by arranging the first experiment cabinet, the second experiment cabinet, the third experiment cabinet and observation glass, the three processes of oscillation, centrifugation and flaking are all in a closed sterile environment, cross contamination is avoided, the internal experiment process can be directly observed through observation glass, waste in the experiment process can be properly treated by arranging a waste box, and centralized treatment is conducted after theexperiment is completed.
