Hydrocyclones as cell retention device for CHO perfusion
Mar 17, 2020· Abstract. In this study, a hydrocyclone HC especially designed for mammalian cell separation was applied for the separation of Chinese hamster ovary cells. The effect of key features on the separation efficiency, such as type of pumphead in the peristaltic feed pump, use of an auxiliary pump to control the perfusate flow rate, and tubing size in the recirculation loop were evaluated in batch separation tests.
