ADVANTAGES Nanojet Control Unit minimum single volume 300 nl Օ maximum repetition frequency 100 Hz contact-less dispensing Օ laminar jet high resistance against aggressive fluids Օ range of nozzle diameter Technology Nanojet dispenser heads feature a miniaturized solenoid valve and a glass capillary nozzle through which the liquid is emitted. The liquid is transported from the reservoir to the dosing head by means of gas pressure.The special nozzle shape provides laminar liquid flow, which prevents liquid from atomizing, thus ensuring that liquid is restricted to the target area. The possible nozzle diameters range from 50 m up to 500 յm.The dispenser volume depends on gas pressure, solenoid valve opening time, nozzle diameter and liquid viscosity. Electronic control of the valve in combination with the pressure control ensures a precisely dispensed volume.Here the work pressure is adjusted between 500 and 3500 hPa with a variation of 1 %. The valve opening time can either be set between 3 ms to 2 s or via trigger input. A serial port is optional available. For functional testing a toggle switch allows the manual opening of the valve. The small dimensions of the heads are particularly advantageous for integration in existing systems. For adaptation of the Nanojet systems to the various fluids two different series of valves are available: Dispenser Head MJ-K-301Dispenser Head MJ-K-103 > Nanojet Dispenser Head MJ-K-103 for watery fluids. Dispensed volumes larger than 100 nl and volume flows up to 2 ml/s. Nanojet Dispenser Head MJ-K-301 with a higher resistance against orga- nic fluids. Dispensed volumes larger than 300 nl and volume flows up to 2 ml/s are possible. replaceable nozzleadapter filter unit liquid supplyelectric supplymagnetvalve housingliquid supplyelectric supplyfilter unit valve housing size="-2">
