Product catalog summary
Overview: The document describes the Nanojet dispenser heads, which are equipped with a miniaturized solenoid valve and a glass capillary nozzle for precise liquid dispensing. The system uses gas pressure to transport liquid from the reservoir to the dosing head, ensuring laminar flow and preventing atomization.
Specifications: The nozzle diameters range from 50 µm to 500 µm. The dispenser volume is influenced by gas pressure, solenoid valve opening time, nozzle diameter, and liquid viscosity. The work pressure is adjustable between 500 and 3500 hPa with a 1% variation. Valve opening time ranges from 3 ms to 2 s, with an optional serial port for control.
Advantages: Key benefits include a minimum single volume of 300 nl, a maximum repetition frequency of 100 Hz, contact-less dispensing, laminar jet, and high resistance to aggressive fluids.
Dispenser Heads: Two types of dispenser heads are available: MJ-K-301 for organic fluids with volumes larger than 300 nl and MJ-K-103 for watery fluids with volumes larger than 100 nl. Both can achieve volume flows up to 2 ml/s.
Technical Data: The MJ-K-301 head has a permissible liquid viscosity of 0.4 to 20 mPas, while the MJ-K-103 allows 0.4 to 50 mPas. Both have a nozzle diameter range of 50 to 500 µm and can operate at ambient temperatures up to 55°C and 60°C, respectively. The maximum working pressure for MJ-K-301 is 3500 hPa, and for MJ-K-103, it is 700/3500 hPa.
Control Unit: The control unit offers multiple operating modes, including test, trigger, and gate modes, with LED displays for operating mode and valve state. It requires a power supply of 15 W, 100 to 250 VAC, and compressed air supply of 4000 to 8000 hPa.
Basic Components: The system includes micro dispenser heads, solenoid valves, replacement nozzles, pressure control units, and storage bins with various capacities.
Contact Information: The document provides contact details for microdrop Technologies GmbH, located in Norderstedt, Germany.

MJ-K-103 to MJ-K-301 solenoid valve dispense head -1

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">
