A small tube-like container with straight sides and a circular or square cross-section makes a cuvette that is sealed at one terminal and composed of an explicit, transparent material that can be plastic, glass, or fused quartz (quartz cuvettes come with a variety). These cuvettes are planned to possess samples for spectroscopic analysis. Here a beam of light is passed through the sample, which lies in the cuvette to measure the ability to absorb, ability to transmit, the intensity of fluorescence, fluorescence polarization, or fluorescence lifetime for the sample. These analyses are executed with a spectrophotometer.

These cuvettes come in a wide variety of materials lets have a look in detail:


Fast spectroscopic assays often use plastic made cuvettes. In the respective context, speed matters more than the level of exactitude. Plastic cuvettes usually come up with a wavelength ranging from 380–780 nm that may be disposed of after using it that prevents contamination from reuse. The plastic cuvettes are very reliable to produce and for purchasing. Disposable cuvettes can generally be used in some laboratories having the beam light, which is not high enough for affecting the immersion endurance and flexibility of the value.


The glass cuvettes are something better than plastic units. These glass cuvettes come with an optimal wavelength that ranges from 340 to 2500 nanometers. These are so convenient to use and are efficient in the way these cuvettes are composed, typically used in the wavelength that comes in a range of visible light. In contrast, the cuvettes composed of fused quartz direct are preferable to be used for ultraviolet applications.


Quartz cuvettes belong to the primary category of cuvettes used generally for photo spectrometers. More sub-categories like fused quartz and infrared cover the vast market of these cuvettes. These quartz corvettes come with more endurance than plastic or glass corvettes. Quartz cuvettes transcend at emitting UV light, and these are generally used for wavelengths that range from 190 to 2500 nm.

Fused quartz

Merged quartz cells are used for wavelengths below 380 nm, for example, ultraviolet light.
Fused quartz or fused silica varies from general glasses that do not contain other ingredients that are usually combined to the glass for lowering the melt of temperature—having a high working and melting temperature. The thermal features of the fused quartz are preferred to those of fused quartz and other types of glass due to its purity. For these durable aesthetic qualities such as semiconductor fabrication and laboratory equipment, it is used in the circumstances, e.g., semiconductor fabrication and laboratory equipment.

Infrared quartz

Infrared quartz comes with a usable wavelength ranging from 220 nm to 3,500 nm. These infrared quartz are more repellent to the chemical attack that comes from the specimen solution more preferable than the rest of the types that are designed for fluorescence measurements.


Sapphire cuvettes are the most expensive genre of the cuvettes, which provides the most enduring, scratch repellent, and emitting material. The transmission of sapphire cuvettes prolongs from UV light to infrared light, which ranges from 250 to 5,000 nm. Sapphire cuvettes can confront the ultimate contingency of some sample solutions and variances in temperature.
