Hi Jose, Typically, we just insert tubing directly into our PDMS devices. You should make sure that the hole in the PDMS is slightly smaller than the outer diameter of your tubing, but the PDMS will hold it in up to pretty reasonable pressures, and the seal will be water tight. I've tried using several different epoxies on PDMS, but none have sealed irreversibly. Josh On Tue, Jul 1, 2008 at 9:56 AM, Jose Guevarrawrote: > Hi, > > I'm working on a cytometer made of PDMS.
