Cuvettes to be used in fluorescence spectroscopy must be clear on all four sides because fluorescence is measured at a right-angle to the beam path to limit contributions from beam itself. Some cuvettes, known as tandem cuvettes, have a glass barrier that extends 2/3 up inside, so that measurements can be taken with two solutions separated, and again when they are mixed. Typically, cuvettes are 1cm (0.39in) across, to allow for easy calculations of coefficients of absorption. These cuvettes may hold up to 4.375 mL when filled to the edge, but the cuvette volume is determined at 80% capacity. When liquids are too close to the top, the sample is more likely to volume of a cuvette spill onto your lab station, spectrometer or gloved hands.

Simplified sheath flow cuvette design for ultrasensitive laser induced fluorescence detection in capillary electrophoresis. Fiber optic illumination of a poly sheath flow cuvette for diode laser induced fluorescence detection in capillary electrophoresis. Fluorescence measurements are typically made by optically "exciting" the same solution at a 90-degree angle to the spectrometer system. These are known as "four sides clear" or fluorescence cuvettes. Shorter and longer path length options are also available. A cuvette spacer or mount can help accommodate shorter path length cuvettes in standard spectrometers.
