Memetis Normally Closed microvalves are designed for microfluidics: ultra-compact (total footprint of 20 mm) with an internal volume of less than 6.5 µL, they can easily be integrated into your lab-on-chip.

The valves are either controllable with your own controller or with an electrical control unit.

Memetis miniature valves are based on a shape memory alloy in an ultra-compact housing, allowing completely silent operation in various environments, from microfluidic chips to incubators.

Normally closed
PEEK housing
Media-separated valve to avoid cross-contaminations
Very low internal volume (< 6.5 µL)
Ultra-compact, reusable, and biocompatible: ideal for on-chip integration
Noiseless system
Easy to use and easy to install on your microfluidic platform
Sterilizable by autoclaving
The slow switching process makes it particularly suitable for applications that react sensitively to fast flow movements.

Tip: Use the Memetis Fluidic Adapter for a convenient connection to your microfluidic system without further customization! The Electrical Control Unit is also available to control up to 2 valves easily.
