Microfluidic Connectors

Featuring CorConneXTM Technology
Rapidly make non-permanent, leak-tight fluidic connections on the surface, or side, of a microdevice.

Benefits

  • Rapidly established, user-friendly connections
  • Connections are non-permanent
  • Allows for tighter density of microchip ports
  • Wide variety of fittings or adapters can be used
  • As the approach does NOT use adhesion, fittings are reusable
  • Connections are compatible with all substrate materials including PDMS, glass, silicon and plastics
  • Connections remain leak-tight at greater than 500 psi
  • Highly reproducible connections
  • Can seal at any location on the surface or side of the device
  • Top-side and back-side alignment
  • Connections are lower dead-volume than conventional approaches
  • Can be used for final performance assessment, and for chemistry treatment of devices during fabrication

How it Works

Mount
The connectors mount to a flat surface with either a screw (1/4-20 or M6) or a magnet.
End Attachment
The end attachment portion of the connector is specific for a tubing or adapter size.  This attachment is removable and can be easily exchanged. Please see below for example end attachments.
Compression Seal
The connector makes a compression seal between a gasket, held by the connector arm, and the microdevice.  The amount of compressive force applied can be adjusted.  Depending on the microdevice substrate material, the compression seal can remain leak tight at greater than 500 psi.
