The eco-PEN 300/450/600, developed by ViscoTec, is a new and innovative constant-volume volumetric dispenser, suitable for micro-volume dispensing of low to medium viscosity liquids in diverse applications.
- Highly accurate micro-volume volumetric dispensing, free of the influence of change in viscosity
- Stable dispensing independent of the initial pressure as well as excellent pressure tightness that eliminates the need for valves
- Suck-back effect reliably stops liquids at the end of dispensing. It prevents liquids from dripping, resulting in excellent finish to pattern drawing.
- Simple structure and easy maintenance
