Hi, I made some channels in the PDMS and punched holes at the end of channels. Glass slide was bond to PDMS and form the wall of the channel.Plastic tubes (PEEK tubes)were inserted in the holes and fixed by various epoxy ester.Solution was pumped into the channels and always leaked. The glue cannot fast adhere to the PDMS.Can someone give me some advice on gluing the PDMS and the tubes? Thanks LeiShenzhen applied R&D centres of city University of Hong Kong Shenzhen Virtual Univ.
