Description

technical field

[0001] The invention relates to the field of cell detection equipment, in particular to a centrifugal filter device for cell preservation. Background technique

[0002] In the production process of liquid-based cytology technology, when cells are subjected to centrifugal filtration and sedimentation for production, sample transfer machines, film production machines, pipetting syringes, centrifuge tubes, film production chambers (or film production clips), Various instruments, equipment and devices such as glass slides are costly. During the operation, samples need to be manually transferred or added between multiple instruments and equipment. The process is cumbersome and lengthy; and when transferring and adding multiple cell samples When sampling, it is easy to have upside-down and cross-contamination phenomenon in human operation, which seriously affects the accuracy of cell detection; samples are easily lost and polluted people, objects and the environmen...
