Micro dosing system design requires multifaceted knowledge of fluid mechanics, elastomechanics, electrical engineering, surface physics, chemistry and phase transformation. Understanding the interactions between these factors is essential to enable flawless interaction of all components in a micro dosing system. In order to further optimize the performance and reliability of the micro dosing systems, the researchers are continuously working on new solutions - for example, in the management of bubbles, particles and counterpressures, monitoring the dosing of the smallest quantities or chemical resistance.
