The less the amount of material to be mixed, the greater the challenge for the dosing system: Due to the World’s increasing miniaturisation in areas such as electronics and the associated high demand for ever smaller and more precise dosing, preeflow has developed the eco-DUO330. This system provides the answer to numerous questions from application engineers, material manufacturers, plant engineers and product developers. Be it in medical technology, optics and photonics, the manufacture of electronic components or in the field of biochemistry and the production of semi-conductors.

Adherence to the exact mixing ratios of the 2 component materials and its precise coverage can greatly influence the processes and applications from time to time. Even small deviations can negatively affect the desired results. Compounds harden only partially, adhesive bonds do not reach their load limit and, in the worst case, chemical reactions from the materials could have an unforeseeable impact on the user.

With the newly developed eco-DUO330, dosing quantities of 0.005 ml (per shot) is achievable. Irrespective of temperature, time, pressure and viscosity – dosed as a dot or bead. Therefore, the smallest quantities can be created at that very moment. The microprocessor-controlled system creates a dosing accuracy of ± 1 % and repeatability of over 99 %. And this whole process is reliable and reproducible.

The technique of process intensification and micro reaction technology has exceeded the laboratory stage recognizably for some time. Hence, the interest in the practical implementation in production processes for the manufacturing of fine chemicals and pharmaceutical products is high. The associated scale-up requires the adaptation of system components. With regard to metering pumps, this development means the realization of larger dosage volumes and flow rates at consistently high precision. Therefore, HNP Mikrosysteme offers with mzr® 11558 the next size of their hermetic inert pump series of micro annular gear pumps.
