Microfluidic Chips with Cross-Channel

A fused silica chip with a cross-shaped microfluidic channel connecting two input ports to one output port.

Available in several channel widths and channel depths, top-down or bottom-up version.

Our Cross-channel chips have microfluidic channels with an optically clear (transparent) ceiling and a translucent floor.  This feature still allows you to visually monitor the microfluidic flow from both sides. If you prefer to have both the floor and the ceiling to be transparent, please check out our selection of flow cells.

These microfluidic chips are available with or without connectors:

  • Without connectors -- part number ends with –N
  • With Luer connectors -- part number ends with –L
  • With UpChurch Nanoport connectors -- part number ends with -U

** Please note that the bonding agent may extend beyond the connector footprint
