Biogenstar BCTF single-pass perfusion bioreactor system, as an innovative perfusion bioreactor, consists of a disposable bioreactor and a pulsed tangential flow filtration system (Impulse Tangential-flow Filtration, ITF), which provides a complete, low-shear cycle solution for cell perfusion culture. Through the control of the weighing system and the peristaltic pump group, the integrated and intelligent process control is realized, and the high-density cell perfusion culture and continuous liquid exchange are easily realized.
