Endless piston technology ensures stable dispensing without pulsation
Positive displacement high-precision microdispenser Preeflow®
preeflow® eco-PEN300/450/600/700 3D
The preeflow® eco-PEN 300/450/600/700 3D high-precision positive displacement microdispensers are capable of precisely dispensing a wide range of fluids, from low to high viscosity. The dispenser body features a completely sealed structure consisting of a rotor and stator, and the controlled rotation of the rotor ensures highly accurate volumetric transfer while maintaining a high level of airtightness without affecting the material’s properties. The suck-back function also prevents dripping, maintaining a clean work environment.
- Achieves a discharge accuracy of ±1% with a positive displacement type (at 1° per rotation)
- Stable continuous discharge without pulsation is possible
- Excellent liquid drainage due to suck back function
- Discharge flow rate (ml/min, g/min) can be set
