2/2 Way Microfluidic Miniature Valve
- Product SKU: MM-22-NC
- Category: Memetis, Microfluidic Valves, Pumps & Flow Controllers, Shape-memory Alloy Valves
The 2/2 normally closed (NC) valves are designed for microfluidics: utra-compact (total footprint of 20 mm) with an internal volume of less than 4 µL, they can be integrated to your lab-on-chip easily.
The valves are either controllable with your own controller, or with an electrical control unit (up to 2 valves).
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.
Features & Benefits
- Normally closed
- Media-separated valve to avoid cross-contaminations
- Very low internal volume (< 4 µL)
- Ultra compact, reusable and biocompatible: ideal for on-chip integration
- Noiseless system
- Easy-to-use and easy to install to your microfluidic plateform
- The slow switching process makes it particularly suitable for applications that react sensitively to fast flow movements
More information in the datasheet.
Note that if you wish to manufacture your own fluidic backplane, you can use the PDMS sealing discs supplied to seal the valve against the backplane. For this purpose, milled recesses 0.25 mm deep must be provided on the fluidic plate.
Tip: Use the Memetis Connector for convenient connection to your microfluidic system, without further customization! The Electrical Control Unit is also available to easily control up to 2 valves.
