  • Microfluidic sieve valves
    Patent number: 8932461
    Abstract: Sieve valves for use in microfluidic device are provided. The valves are useful for impeding the flow of particles, such as chromatography beads or cells, in a microfluidic channel while allowing liquid solution to pass through the valve. The valves find particular use in making microfluidic chromatography modules.
    Type: Grant
