What is cuvette?

A cuvette is a small, transparent vessel used in chemical and biological experiments to hold samples for analysis. Cuvettes are typically made of glass, quartz, or plastic, and come in various shapes and sizes depending on the specific application.

Cuvettes are commonly used in spectrophotometry, where they are used to hold samples for the measurement of absorbance or transmission of light. They are also used in fluorescence spectroscopy, where they are used to measure the fluorescence of a sample when exposed to light of a specific wavelength.

Cuvettes are designed to be optically clear to allow light to pass through the sample without interference. They also have flat, parallel sides to minimize light scattering and ensure accurate measurements.

Cuvettes are available in disposable and reusable forms, with reusable cuvettes requiring cleaning and careful handling to maintain their optical clarity. Some cuvettes also come with caps or lids to prevent contamination of the sample.

Overall, cuvettes are an essential tool in many scientific disciplines for the accurate measurement of light absorbance, transmission, or fluorescence of samples.
