Abstract
The present invention concerns the field of microreaction devices and of micro-process engineering. It particularly involves devices having micro-channels (internal chambers of micrometric to submicrometric dimensions) for conveying chemical or biochemical mixtures and/or reactions. More specifically, such devices are optimized to achieve high temperature and pressure stresses (i.e. 500° C. and 500 bar). For observation and analysis purposes, the microreaction devices have a wide range of transparency in terms of wavelengths. The subject matter of the present invention relates to a microfluid or microreactor device made of transparent sapphire, preferably in the wavelength range of 150 to 6500 nm, its manufacturing method and to its use.
