Choosing cuvettes for UV vis spectroscopy might be difficult. Not all cuvette materials are suitable for every experiment; therefore, basics are needed. This article explains the most important UV vis cuvette buying factors.
Cuvette Material Decomposition
When choosing a cuvette, the material is most crucial. Cuvettes are made from several materials. The three most common cuvette materials are:
UV Quartz R Quartz
Each material has advantages and disadvantages. Again, your application will decide which alternative is best. The first is optical glass.
If you’re on a tight budget, pick a glass cuvette. This cuvette material transmits between 340 and 2,500 nm in the visible band. Most applications occur within this range, and many researchers do not need quartz’s UV range (190-340 nm).
UV Quartz may have better performance than glass. Quartz has a higher price tag but can transmit wavelengths from 190 to 2,500 nm. In order to do research on ultraviolet light, a UV quartz cuvette is required. If you spend a small amount of money on a UV cell that is of poor quality, you should not expect reliable results.
IR Quartz is the material of choice for UV vis cuvettes. Since the transmission range extends from 220 to 3,500 nm, both ultraviolet and infrared light is passed through.
