Normally Closed 2/2 Microvalves
- Product SKU: MM-22-NC-PEEK
- Category: Memetis, Microfluidic Valves, Pumps & Flow Controllers, Shape-memory Alloy Valves
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.
