Design
Atropos-2 is an super compact Drive Unit supporting the Euterpe type of Single-Use-Pump cell's.
Euterpe is a unique stand-alone Air-Operated-Diaphragm-Positive-Displacement (AODPD) Single-Use-Pump (SUP) cell. The Euterpe 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's and sensor's. No nano size silicone particles polluting the liquid. No need for calibration. Check out under Euterpe features!
Driving Euterpe SUP's requires pressure above and vacuum below atmospheric pressure. The SUP cell drive gas pressure is continuously adjusted by two sets of proportional valves inside Atropos. Intelligent microprocessor with advanced PID algorithms get information from Laser and pressure sensor's.
Atropos-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 sensor's. Further Atropos-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.
Specification
When Atropos is connected to gas supply from both a pressure and vacuum source with sufficient capacity, then the spec is:
- Drive of two Euterpe SUP cell's
- Pumped volume (Cardiac Output) according to stroke length and cell size
- Stroke length, %: 10 - 100 in 10% steps
- Atropos can inform about a velocity according to a specified diameter, m/s: 0,1 – 15

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" 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 pulsation when several Euterpe SUPs operate on the same source of supply gas.
Atropos can off course be driven by in lab installed pressurized air and vacuum.
