• Description 

The new eco-DUO330 precision-volume dosing unit made by ViscoTec doses smallest quantities which until now have not been achieved.

  • Theory of function
    The preeflow eco-DUO is a rotating, absolutely pressure-tight, positive displacement system with self-sealing rotor-stator arrangement. The controlled rotary motion of the rotor transfers the medium by displacement in the stator. The medium is unchanged by this process. And simply by switching to reverse-flow, preeflow ensures a clean and controlled stop of materia or medium. No drips, no mess!
  • Smallest dosing quantity: 0.005 ml
  • Adjustable dosing flow: 0.1 – 6.6 ml/min
  • Weight:  ca. 1,100 g
