Method and device for automatic cell centrifugal cleaning and medium replacement

Abstract

A method for automatic cell centrifugal cleaning and medium replacement includes: obtaining a cell volume and a critical value of a centrifugal device after centrifugal stabilization of the centrifugal device; and performing, according to a magnitude relationship between the cell volume and the critical value of the centrifugal device, a velocity reduction process on a centrifugal chamber by combining the cell volume and the centrifugal chamber information. The extracted volume is changed by velocity-reduced rotation, and the rotation at a reduced velocity is adjusted according to the magnitude relationship between the cell volume and the critical value of the centrifugal device. The optimal cleaning and medium replacement effect on cells of different volumes can be realized. A high capture rate and a high medium replacement rate are obtained and maximized from different volumes of cell samples in the fixed parameters of the centrifugal chamber.
