Process for assembling elements contacting biological substances

The present invention relates to a biomedical device for the distribution or containment of biological substances comprising at least two components (11, 14) assembled each other with an adhesive composition (15) comprising a mixture of an acrylic adhesive composition and an epoxy adhesive composition, and particularly thermal or piezoelectric ejecting devices, and biochip microarray. The present invention also relates to a method for assembling a biomedical device comprising at least two components, wherein said process comprises the steps of (i) forming a film of an adhesive composition comprising a mixture of a (meth) acrylate adhesive composition and an epoxy adhesive composition on at least one surface of said at least two components, (ii) precuring said adhesive composition with an UV-blue radiation exposure able to substantially cure said (meth) acrylate adhesive composition without substantially curing said epoxy adhesive composition, (iii) contacting said at least one surface of said at least two com
