| 摘要 |
The present invention relates to a cuvette (4) used for spectrophotometrical analyses, in which electromagnetic energy is passed through a liquid sample (8) contained therein. The object of the invention is to make the passage of the electromagnetic energy through the cuvette (4) and the liquid sample (8) independent of the material of the cuvette (4). This is done by providing the cuvette (4) with openings (14, 16; 22, 24) aligned to permit the electromagnetic energy to pass therethrough. The opening (14; 22, 24) in the or each side (12; 18, 20) making contact with the liquid sample (8) contained in the cuvette (4) is adapted to keep the liquid sample (8) within the cuvette (4) by means of its surface tension.
