A cuvette is a small tubular container that comes with straight edges as well as circular or square cross-section used in laboratories. The cuvettes are used to store samples for spectroscopic analysis. A beam of light is passed through the sample to determine its absorption, transmission, fluorescence intensity, fluorescence polarization or lifespan. The spectrophotometer is used to carry out this measurement. Liquid samples are utilized in conventional ultraviolet-visible spectroscopy as well as fluorescence spectroscopy. Often the sample is a solution in which the target material is dissolved. The material is placed in a cuvette and then analyzed in a spectrophotometer.

The smallest buckets have a capacity of 70 micro liters, while the largest have a capacity of 2.5 milliliters or more. Width affects the distance the light travels through the sample and therefore influences how the absorbance value is calculated. The 39-inch light path common in cuvettes makes calculation of the absorption coefficient easier. Although certain tests use reflection and require only one transparent side, most cuvettes have two transparent ...
... sides facing each other, allowing light from the spectrophotometer to flow through them. For fluorescence measurements, the excitation light requires two additional transparent sides that are at right angles to those of the spectrophotometer light. For use with potentially hazardous solutions or to protect samples from air, some cuvettes are equipped with a glass or plastic lid. Forward! And claim the most hidden advantages and benefits of UV quartz cells and 10mm quartz cells with plugs.

What is UV versus cuvette?

The most popular 10 mm quartz cuvettes with stoppers are cuvettes with rectangular test tubes made of quartz material for use in UV-Vis spectroscopy measuring systems. Like conventional test tubes, they are used to store aqueous solutions. Regular test tubes are useful in chemical reactions. UV-Vis cuvettes, on the other hand, are used in UV-Vis spectrophotometers or fluoro meters to determine the transmission or absorption of radiation at a specific wavelength in the UV and visible range of 190 - 2500 nm.

The solution should be placed in the light path of the UV-VIS spectrophotometer. That's what the UV-Vis bucket is for. Normally 80% of the bucket capacity is filled. However, the filling volume differs depending on the bucket. Using a micropipette, the sample is injected directly into the cuvette and the cuvette is ready for use.

Why are cuvettes made of quartz?

UV Fused Quartz Cuvettes is highly transparent in the ultraviolet and visible parts of the electromagnetic spectrum. Because light can pass through the cuvette with minimal or no light absorption, the absorbance of the sample can be measured accurately. We say that quartz has a lower background absorption than glass or any other substance.

The high thermal stability of quartz cuvettes enables precise measurements under different temperature conditions and ensures reproducible results in sample evaluation.

Quartz is chemically inert and resistant to a variety of common solvents and chemicals. Most substances do not react with it, allowing repeatable measurements without being affected by cell degradation.

UV Fused Quartz Cuvettes is a hard and durable material, making it less prone to scratches or damage during handling and cleaning.

For training purposes in an educational institution, we can use the glass cuvette, but due to the property of glass to absorb ultraviolet light mainly below 350nm, it is not a suitable material for spectroscopic analysis, but in the range visible to students For training you can use the glass. buckets as they have a lower price. Today's high-quality plastic is also used to produce cuvettes for UV spectroscopy.
