Jenway 060-254 Macro Glass Cell Cuvette for Fluorimetry, Visible Wavelength, 4 Windows, 10 x 10mm Path Length

The Jenway 060-253 glass fluorimetry cuvette has a path length of 10 x 10mm. This macro fluorimetry cuvette is used to take visible wavelength measurements from about 380 to 780 nanometers (nm). The glass is clear on four sides to take measurements at right angles.

Cuvettes are specialized test tubes, used in laboratory or field research, to hold samples for optical analysis by instruments such as spectrophotometers, fluorometers, and turbidity meters. Their size or capacity is most often measured in milliliters or microliters. A cuvette may be cylindrical in shape, but square or rectangular cuvettes are used when light refraction must be minimized. A rectangular cuvette may have four clear sides, for use in a fluorometer, or only two clear sides opposite each other, for use in spectrophotometry. The path length of a cuvette, often given in millimeters or centimeters, is a measure of the distance that light travels through a sample in the cuvette. Cuvettes are made of transparent quartz, glass, or plastic. Each material offers different advantages: quartz is best in the ultraviolet light range, glass and plastic in the visible light range, and glass yields more precise results. Cuvettes may come with a cap for containment or a stopper for sealing. Cuvettes are also called cuvets, absorption cells, or sample cells.
