Hello, I need an interconnect for a silicon microfluidic device that I can pull a weak vacuum on, then crimp the interconnect closed and remove the vacuum source (tubing) and still maintain a weak vacuum inside the microfluidic device. Does anybody have a suggestion on where I can obtain such an interconnect or nozzle, and then attach it to my silicon microfluidic device? The diameter of the hole in the silicon substrate that the interconnect attaches to is approximately 80um. Thanks.
