Micro-Jet valves - high speed for contactless dosing

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
