Microreactor manufacture and solution concentration method

摘要

A method of manufacturing a chemical device comprises taking two members, each with a surface portion, and a groove in one of the surface portions. Means heatable and curable via electromagnetic radiation effect or assist linking of the surface portions to close the groove so as to form a channel. Also disclosed is a the making of a solution of desired concentration by controlled contact of a solute with a solvent, in particular by passing the solvent through a porous solute which may be located in a channel of a micro-reactor.
