1-component industrial dispenser for precision dosing
In industries where highly precise dosing of fluids is crucial, maintaining consistency and control is often a challenge. Applications such as bonding, optical bonding, and conformal coating demand exact quantities down to microliters to ensure product quality and efficiency.

Achieve precise and consistent fluid dosing
The eco-PEN series by preeflow, from Visco Tec, offers high-precision volumetric dispensing for single-component fluids. Utilizing the endless piston principle, the eco-PEN devices can handle low viscous to pasty materials with consistent accuracy. The series includes models like the eco-PEN XS 180, eco-PEN300, eco-PEN330, eco-PEN450, eco-PEN600, and eco-PEN700 3D, each offering unique specifications such as adjustable dispensing flow rates and precise control. For instance, the eco-PEN XS 180 can dispense as little as 0.25 µl with an accuracy of ±1%, making it suitable for applications requiring minimal variation in dosing quantities. The design integrates a self-sealing rotor and stator, ensuring spill-free operations. Additionally, the adjustable flow rates across different models allow for flexible application in manual or automated settings. The eco-PEN series is equipped with features like a suck-back function to prevent dripping, making them suitable for tasks in industries ranging from electronics to pharmaceuticals.
