Staiger launches media-separated micro valve with an outer diameter of just 5 mm

Staiger is known in the fluidics world for small, precise and fast solenoid valves with a very long service life. The company has now launched the smallest and fastest solenoid valve to date in a media-separated version. The valve has an outer diameter of just 5 mm and can dispense liquids with a switching time of just 1 ms and a precision of 10 nL without special control electronics. The very short switching time also results in a very high repeat accuracy, which enables extremely precise dosing processes at high speed. These properties are particularly relevant in applications such as in vitro diagnostics (IVD), laboratory automation, pipetting or inkjet printing, where it is important to be able to dispense very small quantities of liquid quickly and precisely.

Alongside other technologies, such as piezo, shape memory or linear actuators, which are used as drives in valves, electromagnets are still the most cost-effective and robust solution in valve technology, also in terms of actuation.
