Clotho stereo software controls the Clio or Thalia LASER guide diaphragm Single-Use-Pump's integrated with the Perfusion-Single-Use-Bioreactor (P-SUB's) for high cell density cultivation.

  • The CellRetention P-SUB for ATF method integrate the Thalia diaphragm Single-Use-Pump (SUP)
  • The CellMembra P-SUB for TFF method integrate the Clio diaphragm Single-Use-Pump (SUP)

Both P-SUBs integrate further the Hollow-Fibre-Filter (HFF) and the pressure Single-Use-Sensors (SUS) - all in one package ready to use. Clotho controls accurately the pumped volume, number of strokes and the velocity. The Clio family is remarkable as there is no need for external mass-flow or pressure sensor's or even manual calibration is needed.

Driving diaphragm SUP's requires pressure above and vacuum below atmospheric pressure. The SUP drive gas pressure is continuously adjusted via a set of proportional valves inside Clotho. Intelligent microprocessor with advanced PID algorithms get information from Laser and internal pressure sensor's.

Clotho-2 stereo model in U2 Hephaestus Stainless Steel cabinet shown as rendered picture. In the middle shown as the real unit including the two red laser sensors. Further Clotho-2 assembled with one Sarpedon reservoir and two Alagonia pumps in one compact tower. This fully independent setup ready to use right out of the box.


When Clotho is connected to a pressure and vacuum source with sufficient capacity, then the spec is:

  • Stroke frequency, per minute: 1 - 60 (depending on pressured air / vacuum capacity)
  • Stroke duration, seconds: 1 - 60 (depending on pressured air / vacuum capacity)
  • Clio as integrated with CellRetention - HFF broth velocity, m/s: 0 – 10
SUP name Thalia - Clio Thalia - Clio Thalia - Clio Thalia - Clio
SUP size M80/60 M80 M100 M140
Stroke Volume, SV, mL/stroke   60 200 500
Cardiac Output, CO range, mL/min   0-900 5-3,000 10-6,000

Suitable drive gas pumps, as well in the Hephaestus cabinet, for supply of pressure and vacuum for Clotho are Alagonia. Check out the Sarpedon reservoir stabilizing pressure/vacuum and reduce pulsation when several Clio or Thalia SUPs operate on the same supply. Sufficient supply is your planned CO x 50% at >2 Bar pressure and CO x 50% at >950 mBar vacuum.

Clotho can of course be driven by in lab installed pneumatic air and vacuum.
