Title:

STIRRER AND ANALYZER

Document Type and Number:

WIPO Patent Application WO/2007/099679

Kind Code:

A1

Abstract:

Provided are a stirrer (20) comprising a container (7) receiving a liquid to be stirred and a surface acoustic wave element (22) radiating sound wave to the liquid so as to stir the liquid by the sound wave, and an analyzer. The surface acoustic wave element (22) in the stirrer comprises a piezoelectric substrate (22a) and a sound generation part (22b) generating the sound wave for stirring the liquid. The sound generation part (22b) is provided on the piezoelectric substrate and disposed on the outside of the container adjacent to the liquid via the container and the piezoelectric substrate. The surfaces of the container and the piezoelectric substrate through which the sound wave is transmitted have a roughness smaller than the wave length of the sound wave generated by the sound generation part.
