Exempel på hur man kan använda CUVETTE i en mening

• Cuvettes are designed to hold samples for spectroscopic measurement, where a beam of light is passed through the sample within the cuvette to measure the absorbance, transmittance, fluorescence intensity, fluorescence polarization, or fluorescence lifetime of the sample.
• A photometer or spectrophotometer is used to measure the attenuation of deep blue (violet) light at 430 nm, as it passes through 1 cm of beer contained in a standard 1 cm by 1 cm cuvette.
• The method involves the use of a spectrophotometer or photometer to measure the attenuation of light of a particular wavelength, 430 nanometres (blue), as it passes through a sample contained in a cuvette of standardised dimensions located in the light path of the instrument.
• The other techniques, based on colorimetry, may require larger aliquots of a sample so that the amount of the coloured soluble products produced is large enough to colour the content of the assay cuvette to a colorimetrically readable level.
• At Sèvres the shape evolved from a vase with no lid, the cuvette à masques, produced from 1754 (earliest example, at Houghton Hall), and the shape of the pot pourri à vaisseau was also used in an adaptation as a lidded tureen with a stand, the terrine gondole from at least 1757 (two in the Hofburg Palace in Vienna), and a different pot pourri gondole.
