Fast and precise dosing with micro-jet valves

For pressures up to 50bar and switching speeds up to 4000Hz, the Inline Micro-Jet valves are particularly suitable for dosing tasks in the nanolitre to microlitre range. Nozzles in the range from Ø 0.1mm to Ø 0.45mm enable contact-free dosing. The possibility of heating the valves up to 100°C allows the dosing of highly viscous media such as oils or greases.

Time-Pressure dosing with fast switching micro-jet valves

If a medium is placed under constant pressure and this pressure is precisely controlled, the micro-jet valves can be used to precisely dose the smallest droplets down to the nanoliter range. Such systems offer various advantages in comparison to other dosing systems, such as:

  • Very high accuracy and reproducibility
  • Very fast dosing speed
  • Pulsation-free dosing
  • Dosage of very small quantities (nanoliters)
  • Variable dosage range
  • Dosing media with different viscosities (also highly viscous media possible)


Through various configuration options of the micro-jet valves and also extensions such as the valve heater or the attachement nozzle, new areas of application can be opened, such as:

  • Dispense highly viscous media up to 15000 mPa.s (by using the valve heater)
  • Semi-touch dispensing applications
  • Jet and slow drop to avoid splashes (satellites)
  • Aspirating & pipetting of media with the attachement nozzle
