CellTank series 34

Continuous Perfusion SUB regulating biomass with temperature

CellTank series 34 is a novel Continuous-Perfusion-Single-Use-Bioreactor (CP-SUB) designed for steady-state continuous cultivation at high density of adherent as well as suspension type of mammalian cells for expression of biologics. CellTank P-SUB is a ready-to-use, pre-assembled in a pre-sterilized package designed for biomass control by temperature regulation.

CellTank is designed for Magnetic-Stirrer-Table (MST) drive operation handled by most Process-Control-Systems (PCS).

CellTank 34 series general specification:

  • Scaffold, matrix either for suspension CHO or adherent CHO cells manufactured from PET
  • Polyamide cover integrated 100% fluid tight with vessel
  • PMP (Polymethylpentene) conical griffin beaker vessel
  • Polyamide reactor body integrating envelopes filled with polyester fibre matrix for enhanced biocompatibility cultivating either adherent or suspension cell lines
  • 4-pole permanent magnet operated polyamide high performance centrifugal pump facilitating simple operation on clock-wise rotation MST
  • Drive by PCS >50 watt servo motor via Magnetic-Stirrer-Table (MST) (MST from www.cercell.com)
  • Efficient elimination of bubble and cell contact and kLa values above 40 sparging with air
  • Very efficient head space to liquid surface contact for high efficient CO2 control
  • Delivered high precision E-beam irradiated in dual polyester foil bags

CellTank facilitates the use of PG 13,5 x 120 mm classical format sensors:

  1. One pre-installed classical signal and type of pH sensor from Hamilton - included
  2. One pre-installed classical signal non-invasive VisiWell with dO2 sensor spot from Hamilton (Visiferm not included)
  3. Extra port for possible glucose and lactate measurements – not included
  4. One port designed for biomass sensor – Hamilton style Re-Usable-Sensors (RUS) – install yourself under sterile conditions – not included

All CellTank further integrate the following sensors:

  • Non-invasive temperature well for <ID6 mm sensors – facilitate your PCS standard probe for on-line measurements
  • internal media re-circulation mass flow – SUS – manual read-out of 0.4 - 2.4 litre/min
  • matrix pressure drop – SUS – manual read-out of 0 – 600 mm WC
  • media level with an insulated SS electrode in 1,300 ml height with the biomass sensor as ground

CellTank 34 available since 2013.
