The cuvettes we sell for our Colorimeter and the SpectroVis Plus are made of polystyrene, which can be damaged by many different types of liquid substances. Examples of common liquids that should NOT be poured into these cuvettes: ketones (acetone, 2-butanone), alkanes (hexanes, heptane), and highly concentrated acids or bases.

The cuvettes we sell for use with UV-VIS spectrometers are made of a proprietary plastic, but many of the same liquids can damage these cuvettes. A compatibility chart is available:

Acetone Poor Poor
Acetonitrile Poor Poor
Benzene Poor Poor
Methylethyl Ketone Poor Poor
Carbon tetrachloride Poor Poor
Chloroform Poor Poor
Diethyl ether Poor Poor
Dimethyl sulfoxide Marginal Poor
Ethanol Poor Poor
Formaldehyde (40%) Poor Poor
Heptane Poor Marginal
Hexanes Poor Excellent
Hydrochloric acid (32%) Marginal Poor
Isopropanol Marginal Marginal
n-Pentane Poor Poor
Oleic acid Poor Poor
Perchloric acid (10%) Poor Poor
Petroleum ether Poor Poor
Phenol Poor Poor
Sodium hydroxide Excellent Poor
Sulfuric acid Poor Poor
Trichloroacetic acid Poor Poor
Trichloroethylene Poor Poor
Toluene Poor Poor
  • Excellent: the properties of the cuvette are not changed after 24 hours of exposure to the chemical
  • Marginal: the properties of the cuvette may not change after 24 hours of exposure to the chemical; testing is recommended before use in an experiment
  • Poor: the cuvette will be damaged within 24 hours of exposure to the chemical

You will need a 10 mm path length cuvette with a nominal volume of 3.5 mL. The width and length should be 10 mm. This is a standard 1 cm^2 cuvette. Many companies sell them. The Starna catalog number for these glass cuvettes is 1-G-10.
