Hi, Robert!
You could attach a tiny thermoplastic tubing by e.g. UV adhesive and after
sucking the air out, you use a heated plier to simultaneously cut and seal.
The smallest tubing of this kind I have seen so far was 250um internal
diameter, 350 external.
Regards,

Erik

Betreff: [mems-talk] Microfluidic interconnect


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.

Sincerely,

Robert Dean
