UHV Cuvettes

Ultra-High Vacuum (UHV) cuvettes are specialized sample holders or containers used in spectroscopy experiments, particularly in the field of ultraviolet-visible (UV-Vis) and infrared (IR) spectroscopy. These cuvettes are designed to work under extremely low-pressure conditions, creating a high-vacuum environment to prevent interference from contaminants and to study the spectral characteristics of samples with high precision.

UHV cuvettes are typically constructed from materials that can withstand the high-vacuum conditions without outgassing or contaminating the sample being studied. They are often made from materials like quartz, sapphire, or other high-purity materials that exhibit minimal absorption in the UV and visible regions of the electromagnetic spectrum.

Applications of UHV cuvettes include studying the electronic and vibrational properties of gases, thin films, and solid-state materials. Infrared spectroscopy, in particular, benefits from UHV cuvettes when researchers need to investigate the vibrational modes of molecules without interference from air or other contaminants. These cuvettes can also be equipped with various windows and ports to allow for sample illumination and data collection using specialized spectroscopic techniques.

UHV cuvettes are an essential tool in advanced spectroscopy research and are commonly used in laboratories that focus on high-precision analysis of materials in vacuum environments.
