Control of one CellMembra or CellRetention
Clotho is a single channel Drive Unit for either of;
- one Clio diaphragm One-way-Single-Use-Pump (O-SUP) integrated with the CellMembra P-SUB
- one Thalia diaphragm Alternating-Single-Use-Exchanger (A-SUE) integrated with the CellRetention P-SUB.
Both for cultivating mammalian cells in a semi Continuous Process.

Design
Clotho-1 software is loaded into the very compact Drive Unit capable of supporting both the Clio type of One-way-Single-Use-Pump and the Thalia Alternating-Single-Use-Pump.
Clio and Thalia may be integrated with a Single-Use-Bioreactor (SUB) for high density cell cultivation operating in perfusion mode. Such as the CellMembra or CellRetention product. The P-SUB integrates with either Clio or Thalia (O-SUP or A-SUP), the Hollow-Fiber-Filter (HFF), the Single-Use-Sensor's (SUS) - all in one package ready to use. Clotho control accurately the pumped or exchanged volume and the velocity of the feedstock passing the HFF.
Driving the diaphragm O-SUP's / A-SUP's requires pressure above and (vacuum) below atmospheric pressure. The drive gas pressure and mass-flow is continuously adjusted via a set of proportional valves inside Clotho. Intelligent software with advanced PID algorithms get information from LASER and pressure sensor's.

Specification
When Clotho is connected to gas supply from both a pressure and vacuum source with sufficient capacity, then the spec is:
- Drive of one Clio O-SUP or one Thalia A-SUP ranging sizes M80, M100 or M140
- Pumped volume (Cardiac Output, CO) according to stroke length and cell size
- Stroke length, %: 1 – 100
- Clotho inform continuously about velocity according to HFF spec input, m/sec: 0.1 – 10
Please check:
Supply gas is defined as: 1 - "Supply gas pressure" and; 2 - "Supply gas vacuum". Sufficient supply is when the volume (measure in "normal liter/min") of both pneumatic pressure and vacuum quality is 1-2 times the planned CO in "nl/min" at specified pressures.
Suitable supply gas pump's, also in Hephaestus cabinet's are Alagonia. Check also out the Sarpedon reservoir stabilizing pressure/vacuum and reduce supply pulsation when several O-SUPs or A-SUPs operate on the same source of supply gas.
Clotho can off course be driven by in lab installed pneumatic air and vacuum
