When the electric sample pump absorbs the coagulation sample, the coagulation tissue blocks the sample tube. The pressure sensor is used to detect abnormal pressure changes in the pipeline, thereby realizing the detection of the coagulation sample. The capacitance sensor is connected to the pipette tip of the electric sample pump through a wire. During the sample absorption process, the pipette tip contacts the liquid surface in the sample tube. The electric sample pump detects the liquid surface by detecting the change in the capacitance value in the circuit, ensuring the accuracy and stability of the pipetting. Before the electric sample pump absorbs the liquid, it mixes the sample through multiple suction and discharge operations to ensure the uniformity of the sample and the quality of the sample.
