cuvette

A cuvette is a small, transparent container used in laboratories to hold liquids for scientific measurements. Typically made of glass, quartz, or plastic, it allows light to pass through the sample so that instruments like spectrophotometers can analyze its properties, such as absorbance or concentration. Cuvettes are precisely manufactured to ensure accurate and consistent results, often featuring specific dimensions and optical qualities. They are essential tools in experiments involving chemical reactions, biological samples, and quality testing, enabling scientists to study substances accurately by observing how they interact with light.
