WPI's glass and synthetic quartz cuvettes are ideal for UV/VIS/NIR absorbance and fluorescence experiments.

For spectroscopy cuvettes, synthetic quartz can be used in deep UV applications and is recommended for fluorescent applications, as it does not exhibit background fluorescence. Our quartz cuvettes (absorbance, fluorescence and flow) are shipped individually packaged. Our glass cuvettes are shipped in packages of 10 cuvettes.

These economical quartz and glass cuvettes are ideal for precision measurements, because of the high quality materials used and the low manufacturing tolerances.

Cuvettes come in a variety of shapes and sizes, but one of the most important specifications of a cuvette is its Z-dimension. The Z-dimension of an instrument (cuvette holder or spectrometer) is the distance from the bottom of the cuvette chamber floor to the center of its light beam (see image). A cuvette’s Z-dimension must match the Z-dimension of the instrument with which it will be used. Compare manufacturers' Z-dimensions and learn how to measure a Z-dimension.
