ADVANTAGES droplet diameter: approx. 35 Վm to 90 ܎m ܕ usable with a wide range of fluids viscosity range 0.4 ... 10000 mPas (depending on the fluid used) Օ can produce a single droplet or a series of droplets Technology Microdrop dispenser heads function according to the same principle as an inkjet printer with a piezo-electrical print head.The liquid is fed through a capillary tube. To emit a droplet, a mechanical impulse is imparted to the liquid column by a piezo ceramic. At the nozzle tip a micro fine droplet is generated, which departs from the dispenser head at high speed. The size of the drop (35-90 μm) depends on the capillary opening. Electronic control of the dispenser heads ensures a high level of dispensing precision as to volume, timing and placement. The procedure can be observed with the help of an integrated stroboscopic LED. Dispenser Head Microdrop dispenser heads are suitable for liquids with viscosities from 0.4 to 20 mPas. For more viscous liquids (up to 10000 mPas), dispenser heads with temperature-controlled nozzle heating and fluid leading parts are available to reduce viscosity. The liquid only has contact with the glass capillary and the PTFE liquid supply. The emitted droplets are placed with high reproducibility levels. Microdrop dispenser heads have no mechanical moving parts and are therefore free of wear and maintenance. > Microdrop dispenser head size="-1">
