Abstract: The invention relates to cover slips coated with covering medium for covering specimens and to machine processes for the production thereof. The cover slips according to the invention greatly simplify the covering of specimens since firstly there is no need to handle the tacky covering medium and secondly the specimens are permanently covered after just a few minutes and can be investigated under a microscope even using immersion objectives. The covering medium layer thicknesses and layer-thickness tolerances according to the invention produce stable and durable covering.

Abstract: 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).
