Nanojet Piezovalve NJ-K-4...

ADVANTAGES • high accuracy due to controlled valve core • frequency from single pulse to 450 Hz (higher frequencies on demand) • valve closed in power-off mode – no dripping and uncontrolled pollution • 24-hours non stop application possible • very long life time • easily exchangeable nozzles for various applications • very good chemical stability • software-controlled temperature- and pressure independent dispensing due to external Control-Unit NJ-E-4... • intelligent upgraded processor with advanced timing and automatically identification Technology This high performance valve was developed for the dis-pensing of liquids in a viscosity range of up to 2000 mPas. The volume range reaches from 8 nl up to 10 µl per dis- pensing cycle. The liquids are transferred without impact of the nozzle just as with all other microdrop microdispenser systems. In combination with the very precise switching perfor- mance of the piezovalve this results in a very high volume accuracy of
