1. What is a Sapphire Cuvette?
A Sapphire Cuvette is an optical sample cell manufactured from synthetic single-crystal sapphire (Al₂O₃) for spectroscopy and other applications requiring high optical quality, chemical resistance, and durability.
2. What are Sapphire Cuvettes used for?
They are used for UV-Vis spectroscopy, fluorescence spectroscopy, Raman spectroscopy, optical analysis, chemical research, high-temperature experiments, and demanding laboratory applications.
3. Why use sapphire instead of quartz?
Sapphire offers much greater hardness, scratch resistance, mechanical strength, and high-temperature performance than quartz. Quartz may provide broader or more convenient optical transmission for certain UV applications, so material selection should be based on wavelength and experimental conditions.
4. Are Sapphire Cuvettes suitable for UV spectroscopy?
Yes. High-quality optical sapphire can transmit ultraviolet radiation and can be used for selected UV and UV-Vis spectroscopy applications. The exact transmission range depends on the sapphire grade and thickness.
5. What optical path lengths are available?
Common optical path lengths include 1 mm, 2 mm, 5 mm, and 10 mm, with custom optical path lengths available.
6. Can Sapphire Cuvettes withstand high temperatures?
Yes. Sapphire has excellent thermal stability, high-temperature strength, and low thermal expansion, making sapphire cuvettes suitable for applications involving elevated temperatures when properly designed.
