Agitation vessel
View Patent ↗Provided here is an agitation vessel which enhances energy transmission efficiency in an agitation apparatus and an analysis apparatus, simplifies the structure of the agitation apparatus and the analysis apparatus, and allows for downsizing and improved maintenanceability. An agitation vessel ( 5 ) agitates retained liquid by sound waves. A sound wave generating member ( 24 ) which generates sound waves is provided integrally with the agitation vessel ( 5 ). The agitation vessel ( 5 ) includes a bottom wall ( 5 d ) and plural side walls ( 5 c ) made of an optically transparent material, and a part of the opposing side walls among the plural side walls ( 5 c ) is a photometric window ( 5 b ) that optically measures the liquid agitated. The sound wave generating member ( 24 ) is arranged on the side wall ( 5 c ), on which the photometric window ( 5 b ) is arranged, among the plural side walls ( 5 c ).
1. An agitation vessel for agitating retained liquid by sound waves, comprising a sound wave generating member and an acoustic matching layer integral with the agitation vessel, the sound wave generating member generating the sound waves that agitate liquid retained in said agitating vessel;
a bottom wall and at least four side walls, wherein
a part of the opposing side walls of the at least four side walls is made of an optically transparent material that transmits analytical light to form a photometric window to optically measure the liquid agitated;
wherein the sound wave generating member is attached to an external surface of any of the at least four side walls or the bottom wall and the acoustic matching layer placed between the sound wave generating member and the external surface of any of the at least four side walls or bottom wall; and
wherein the sound wave generating member includes on a substrate a sound wave generator having one or a plurality of interdigital transducers of a surface-acoustic-wave element, and a power receiver which receives power and transmits the power to the sound wave generator.
2. The agitation vessel according to claim 1 , wherein the bottom wall and at least four side walls are made of an optically transparent material.
3. The agitation vessel according to claim 1 , wherein the sound wave generating member is provided on the side wall, on which the photometric window is arranged, among the at least four side walls.
4. The agitation vessel according to claim 3 , wherein the sound wave generating member is provided at a portion other than a portion where the photometric window is provided in the side wall.
5. The agitation vessel according to claim 1 , wherein the sound wave generating member is provided on the side wall other than the side wall, on which the photometric window is arranged, of the at least four side walls, or on the bottom wall.
6. The agitation vessel according to claim 1 , wherein the sound wave generating member is attached to a depressed portion formed on any of the at least four side walls.
7. The agitation vessel according to claim 1 , wherein the sound wave generating member constitutes one of the bottom wall and the at least four side walls.
8. The agitation vessel according to claim 1 , wherein the at least four side walls retain the liquid on an upper surface of a plate-like member formed of an optically transparent material.
9. The agitation vessel according to claim 1 , wherein the sound wave generating member is attached to the side wall or the bottom wall with the sound wave generator and the power receiver facing inward.
10. The agitation vessel according to claim 9 , wherein the sound wave generating member is arranged on the bottom wall, and the sound wave generator is arranged so that the one or plurality of interdigital transducers are aligned in a horizontal direction.
11. The agitation vessel according to claim 9 , wherein the sound wave generating member is arranged on the side wall, and the sound wave generator is arranged so that each of the one or plurality of 1 interdigital transducers extends horizontally or extends in an inclined direction with respect to a horizontal direction, and the one or plurality of interdigital transducers are arranged along a vertical direction or in an inclined direction with respect to the vertical direction.
12. The agitation vessel according to claim 1 , wherein the sound wave generating member is attached to the side wall or the bottom wall with the sound wave generator and the power receiver facing outward.
13. The agitation vessel according to claim 12 , wherein the sound wave generating member is arranged on the bottom wall, and the sound wave generator is arranged so that the one or plurality of interdigital transducers are aligned in a horizontal direction.
14. The agitation vessel according to claim 12 , wherein the sound wave generating member is arranged on the side wall, and the sound wave generator is arranged so that each of the one or plurality of interdigital transducers extends horizontally or extends in an inclined direction with respect to a horizontal direction, and the one or plurality of interdigital transducers are arranged along a vertical direction or in an inclined direction with respect to the vertical direction.
