A microprocess part having at least one microfluid process element ( 4 ) and having microfluid channel connections ( 9 ) has a thermally insulating housing ( 1 ) surrounding the microfluid element ( 4 ), where the microfluid channel connections ( 9 ) are passed through the housing ( 1 ), and connecting elements for connecting individual housings ( 1 ) are arranged on the housing ( 1 ) in such a way that the microfluid channel connections ( 9 ) associated with each can be tightly connected to one another. The microfluid element ( 4 ) is arranged between a connection block ( 3 ) and a heat transfer block ( 2 ), where the temperature of the heat transfer block ( 2 ) and of the connection block ( 3 ) and thus also of the microfluid element ( 4 ) can be regulated. A connecting element for connecting individual housings ( 1 ) to one another has a conical screw ( 21 ) having a threaded section ( 22 ) and a conically tapering section ( 23 ). A locking pin ( 18 ), which has a hole ( 19 ) matched to the conical screw ( 21 ) and projects out of the first of the housings ( 1 ) to be connected, is introduced into a recess ( 20 ), matched to the locking pin ( 18 ), of a second housing ( 1 ) and fixed by means of the conical screw ( 21 ), whose conically tapering section ( 23 ) engages with the hole ( 19 ) of the locking pin ( 18 ). |
