A device for automatic cell purification and freezing

Abstract

An automatic cell purification and freezing device, the invention belongs to the field of biotechnology, which solves the defects of frequent manual operation steps when separating samples, which easily leads to cell pollution, easily damaged cells and affects biological effects. The cell automatic purification and freezing device includes a purification freezing box, a liquid bag rack, a stop valve, a peristaltic pump, a suspension separation device, and a push injection device. The right side is the cryopreservation area. Multiple peristaltic pumps and a suspension separation device are installed on the middle wall of the electronically controlled purification area. The lower part of the electronically controlled purification area is equipped with a push injection device. Cells are hung on the liquid bag rack. The storage bag, the infusion tube connected to the bottom of the cell storage bag is clamped in the peristaltic pump through the shut-off valve, and the cryopreservation bag and heat sealing device are placed on the pre-mixing platform in the box of the cryopreservation area. The automatic cell purification and freezing storage device of the present invention realizes multifunctional automation, improves operation accuracy and reduces the risk of biological contamination.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a control device for automatic cell purification and programmed freezing, which is used for cell separation, extraction and programmed freezing. Background technique [0002] With the development of biotherapy technology, cell purification technology is gradually optimized and developed, from the initial traditional centrifuge through the control of the corresponding speed to achieve the purpose of layered separation of cells, to the current development of a complete set of sterile pipelines through the centrifuge cup at high speed Centrifugation separates the cell components to the edge, thereby separating the required components, but the separation speed is slow, the noise is large, the cell loss is high, the human intervention is more and the preparation stability is poor. [0003] Program-controlled cooling technology is to use temperature control technology and liqui...
