Eirene and the very compact Drive Unit Metis supports the Melpomene type of CerPhragm Single-Use-Pump.

Melpomene SUP is integrated with the Continuous-Perfusion-Single-Use-Bioreactor (CP-SUB's) for high cell density cultivation. The CellTank CP-SUB integrate one of the Melpomene diaphragm Single-Use-Pump's (SUP). Eirene control accurately the pumped volume and the velocity of the broth passing through the CP-SUB scaffold.

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

Right; Typical setup with one Alagonia for supply of vacuum (or even two Alagonia pumps for both vacuum and pressure) and one Sarpedon reservoir.


When Eirene is connected to gas supply from both a pressure and vacuum source with sufficient capacity, then the spec is:

  • Drive of one Melpomene SUP
  • Pumped volume (Cardiac Output, CO) according to stroke length and cell size
  • Stroke length, %: 10 – 100 in 10% jumps
  • Eirene inform continuously about velocity, m/sec: 0,1 – 15
  • Eirene can of course be driven by in lab installed pneumatic air and vacuum.


  • Internal 5” touch sensitive TFT display or external to PADs or smartPhones via Wi-Fi for programming and info from the built-in webserver
  • USB port for USB adapter/Wi-Fi connection and software upgrades
  • RJ45 for IP/TCP via LAN and ModBus, OPC communication with PCS
  • 24 VDC inlet via one Buccaneer 3 pole connector
