Perfusion-Single-Use-Bioreactor for Continuous Processing

Hi again, allow me to inform more about upstream Continuous Processing 

Single-Use upstream Continuous Processing see ever increasing international interest. Missing is though the 100% pre-assembled and ready to use Perfusion-Single-Use-Bioreactor (P-SUB). We have all used with great pleasure the ATF for almost 20 years. Thanks to Jerry, but now it’s about time for the next technology jump. The CellMembra P-SUB range from as small as 500 ml and up. The P-SUB integrate the customizable Single-Use-Bioreactor (SUB) with the high precision unique Clio Single-Use-Pump (SUP) and Single-Use-Sensor's (SUS) with the single-use Cross-Flow-Filter (CFF).

See for yourself at BPI in Boston end of September.

CellMembra 500 ml P-SUB shown. 1 – 4 x PG13,5 ports for sensors. 2 - Fitted into a foot for liquid or electrical heating. Connected via cable to red Laser sensor and via blue hose to diaphragm pump. 3 – Ultra compact and precise Clotho drive-unit.


CellMembraTM comprises a configurable P-SUB optimised for use in single or in various parallel applications. From the SUB the integrated diaphragm SUP sucks and force the broth along the CFF hollow fibres. The permeate pass through the CFF membrane and retentate returns to the SUB. Pre-installed high-quality Single-Use-Sensors for DO and pH measurements that fits any Process-Control-System.
