Constant flow injection pump system and cell magnetic sorting device

Abstract

The invention discloses a constant flow injection pump system and a cell magnetic sorting device. The constant flow injection pump system comprises a first plunger pump, a second plunger pump, a first check valve, a second check valve, a third check valve, a fourth check valve, a liquid outlet pipe and a liquid inlet pipe; the outlet of the first plunger pump is respectively connected with the inlet of the first check valve and the outlet of the second check value; the outlet of the first check value is connected with the liquid outlet pipe; the liquid inlet pipe is respectively connected with the inlet of the second check valve and the inlet of the third check valve; the outlet of the second plunger pump is respectively connected with the outlet of the third check valve and the inlet of the fourth check valve; the outlet of the fourth check valve is connected with the liquid outlet pipe. According to the constant flow injection pump system, liquid can be kept stable and constant in flow rate, and the flow rate can be regulated; the cell magnetic sorting device is simple in structure, efficient and reliable, and is suitable for continuous high-capacity magnetic cell separation; the device integrates a target cell washing function, therefore sorting and washing are completed simultaneously, and high-quality continuous cell sorting can be realized.
