Why use a quartz cuvettes instead of plastic? Quartz. Quartz cells provide more durability than plastic or glass. Quartz excels at transmitting UV light, and can be used for wavelengths ranging from 190 to 2500 nm.
What is the importance of using a quartz cuvette? Quartz cuvettes deliver precise results in the whole UV and visible range from 200 to 2500 nm. The smaller the manufacturing tolerance, the better and more repeatable the measurement.
Why are glass cuvettes better than plastic? In general, glass cuvettes display greater transparency and accuracy of measurement, and they can be re-used many times. Then again, handling of plastic cuvettes is simple and safe. Since plastic cuvettes are only used once and do not require cleaning, possible damage and loss do not have to be taken into account.
When can plastic cuvettes be used? Plastic cuvettes are used in the visible range for colorimetric assays and the UV range for DNA, RNA, and protein analysis. Semi-micro size cuvettes are for sample volumes between 1.5mL and 3.0mL, macro cuvettes for samples larger than 2.5mL.
