A microanalytical device is provided for conducting chemical processes using small amounts of fluid. The devices include microstructures, e.g., microcavities, microchannels and the like, that are laser ablated or otherwise formed in a support substrate, and can be used in a variety of chemical and biochemical methods, including chromatographic, electrophoretic and electrochromatographic separations, screening and diagnostics, and chemical and biochemical synthesis. The devices are formed from a material that is thermally and chemically stable and resistant to biofouling, significantly reducing electroosmotic flow and unwanted adsorption of solute. Preferred materials are polymeric.
