Sapphire Cuvette

Sapphire Cuvette

A sapphire cuvette is a small, rectangular-shaped cell used in spectrophotometry and other laboratory applications. It is made of sapphire, which is a crystalline form of aluminum oxide. Sapphire is a highly transparent and durable material that is resistant to abrasion, chemicals, and high temperatures. These properties make sapphire cuvettes ideal for use in a variety of analytical and spectroscopic applications where high precision and accuracy are required.

Sapphire cuvettes come in different sizes and shapes, and their optical properties depend on their thickness, surface quality, and orientation. They are commonly used in UV-visible spectroscopy, fluorescence spectroscopy, and other analytical techniques that involve the measurement of light transmission or absorption through a sample.

Sapphire cuvettes are easy to clean and can withstand harsh cleaning agents, making them reusable and cost-effective. They are also non-reactive, meaning that they will not interfere with the chemical or biological properties of the sample being analyzed. Overall, sapphire cuvettes are a reliable and versatile tool for laboratory research and analysis.
