1. A microfluidic device including a microreactor with fluidic inlet(s) and outlet(s) and a connector with fluidic channel(s) into its volume, at least one of said inlet(s) and outlet(s) of said microreactor being connected through said connector characterized in that:
- said microreactor is made of a first material selected from the group consisting in glasses, ceramics, glass-ceramics and metals coated with a glass, ceramic or glass-ceramic coating;
said connector is made of a second material selected from the group consisting in glasses, ceramics, glass-ceramics and metals coated with a glass, ceramic or glass-ceramics coating; and
said connector is sealed on said microreactor via a frit layer made of a third material;
said third material being selected from the group consisting in glasses, ceramics and glass-ceramics, having a lower softening point than the softening point of any glass, ceramic and glass-ceramic of said microreactor and connector and also having an expansion coefficient compatible with the expansion coefficient of any glass, ceramic and glass-ceramic of said microreactor and connector.
