Scratches on the sides of the cuvette the light passes through scatter light and cause errors. A rubber or plastic rack protects the cuvette from accidentally hitting and being scratched by the machine casing. Cuvettes to be used in circular dichroism experiments should never be cuvette mechanically stressed, as the stress will induce birefringence in the quartz and affect measurements. Nest Scientific Standard and UV Cuvettes have a 10mm optical path length and are compatible with most spectrophotometer makes and models.
- Made from JGS1 UV-grade fused silica, absorption onset occurs below 170 nm and there are no absorption bands situated between 170 nm and 250 nm.
- A cuvette is a piece of laboratory equipment that is intended to hold samples for spectroscopic analysis.
- In this measurement configuration, the opposite-side cuvette walls must be optically "clear" to let light pass unimpeded through the sample.
- Cuvette used in UV spectroscopy, you will end up creating trouble in the absorbance studies, and the obtained results won’t be accurate.

Historically, reusable quartz cuvettes were required for measurements in the ultraviolet range, because glass and most plastics absorb ultraviolet light, creating interference. Today there are disposable plastic cuvettes made of specialized plastics that are transparent to ultraviolet light. Glass, plastic and quartz cuvettes are all suitable for measurements made at longer wavelengths, such as in the visible light range.
