Clotho-1 is very compact Drive Units supporting the Clio and Thalia type of Single-Use-Pump's size M80 and M100.

Clotho is the software in the Drive Unit for Clio or Thalia SUP integrated with the Perfusion-Single-Use-Bioreactor (P-SUB's) for high cell density cultivation. Such as the CellMembra P-SUB available from PerfuseCell. The P-SUB integrate the Clio diaphragm Single-Use-Pump (SUP), the Hollow-Fibre-Filter (HFF), the Single-Use-Sensors (SUS) - all in one package ready to use. Clotho controls accurately the pumped volume and the velocity. The Clio family is remarkable as there is no need for expensive external mass-flow sensor's. No need for tools exchanging the SUP cell. No need for bulky pump heads and sensor's. No nano size silicone particles polluting the liquid. No 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 pressure sensor's.

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 CellMembra - CFF broth velocity, m/s: 0,1 – 15

Clio as mounted on CellMembra and the stand-alone Clio O-SUP share the same diaphragm basic dimension. As to this also the same performance like SV ad CO.

SUP name Clio - Thalia Clio - Thalia Clio - Thalia
SUP size M80 M100 M140
Stroke Volume, SV, mL/stroke 60 200  
Cardiac Output, CO range, mL/min 1-450 5-1,500  

Suitable Drive-Gas pumps, also 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.
