Piezo Valves in Biotechnology, MedTech and Diagnostics

The requirements of nanoliter metering in biotechnology, medical technology and diagnostics are extremely demanding: Many different liquids with very different characteristics usually have to be dosed with precision in the manufacture of microarrays and lab-on-a-chip systems as well as in researching active agents.

On the one hand, any cross-contamination must be prevented. On the other hand, the technology used must be able to generate perfect droplets, taking into account the viscosity and surface tension of the media and the dosing speed. Misting, satellite formation on impact or dripping must be prevented to achieve reliable and repeatable results in drug screening, for example.

Piezo components offer many advantages for nanolitre dosing:

Flexible designs: Benders, stack actuators, lever amplification for travel ranges up to 1 mm
High force generation, high acceleration, high operating frequencies
No friction, no maintenance, no wear
Energy saving, stable position when at rest
Large-scale production means low costs
