Description

A cuvette is a small, transparent rectangular receptacle that comes in a variety of materials, quality standards, and dimensions. Glass cuvettes are utilized for visible-range measurements ranging from 310 to 2500 nm. In contrast, Quartz cuvettes provide exact findings across the entire UV and visible spectrum, from 200 to 2500 nm. The more consistent and efficient the measurement, the smaller the production tolerance. Cuvettes store samples for spectroscopic measurements, in which a light beam is sent through it to evaluate its absorption, transmittance, fluorescence emission, fluorescence polarization, or fluorescence lifespan.
Traditional ultraviolet-visible or fluorescence spectroscopy makes use of liquid samples. The experimental sample is poured into a cuvette, and with the help of a spectrophotometer, the researchers can test it. We can develop the cuvette of any transparent material in the wavelength range employed in the test.

The width defines the length of the light path through the sample, which influences the absorbance value computation. The smallest cuvettes have a capacity of 70 microliters, and the biggest has a capacity of 2.5 milliliters or more. The path length of cuvettes is 10 mm (0.39 in), which makes estimating the absorption coefficient easier.

Absorption begins below 170 nm, and there are no absorption bands between 170 and 250 nm in this JGS1 UV-grade fused silica. Exceptionally high transmittance over the UVB, UVA, visible, and near IR spectrums. We suggest IR Quartz Glass Cuvettes when working in the IR spectrum, especially at wavelengths larger than 2000 nm, because they have robust transmission at these wavelengths.

There are mainly two types of cuvette. One is two side transparent quartz cuvette, and another is four side transparent quartz cuvette. The four sides one is quite costly compared to the two transparent cuvettes.
