Micro-capillary for chemical electrophoresis is formed from a thermoplastic plate with an embossed trench to take the electrical conductors without any internal steps

摘要

The micro-capillary is formed from a plate (3) of thermoplastic material with an embossed trench. At least two integrated electrical conductor paths (2) are inserted into the upper surface of the plastics structure (3), within the embossed trench. The trench formed in the plastics structure has an angled wall and rounded edges, at least where the electrical conductors (2) are inserted. The plate (1) is bonded tightly to a cover, with external access to the conductors (2) through access openings into the trench. An Independent claim is included for a producing the micro-capillaries, where electrical conductors are fitted to at least one surface of a workpiece of a thermoplastic material.
