FAQ
Q: What is a Micro Fluorescence Quartz UV Cuvette?
A: A Micro Fluorescence Quartz UV Cuvette is a small sample container made from high-purity quartz glass, designed for spectroscopic analysis of micro-volume samples. Our model features four polished sides for multi-directional light transmission and a secure lid to prevent sample evaporation and contamination during analysis.
Q: Why use a Micro Fluorescence Quartz UV Cuvette with Lid?
A: These specialized cuvettes are essential for applications requiring high optical clarity across UV-visible wavelengths (200-2500nm), minimal sample volumes (50-200μl), and protection from evaporation or contamination. The four polished sides allow for fluorescence measurements where excitation and emission light paths are perpendicular to each other, unlike standard two-window cuvettes.
Q: What is the wavelength range of your Micro Fluorescence Quartz UV Cuvette?
A: TOQUARTZ® Micro Quartz Glass UV Cuvettes have an optical transmission range of 200-2500nm, covering the ultraviolet, visible, and near-infrared regions. This wide spectral range makes them suitable for diverse analytical applications including UV-Vis spectroscopy, fluorescence spectroscopy, and NIR analysis.
Q: What is the path length of your Micro Fluorescence UV Quartz Cuvette?
A: TOQUARTZ® standard Micro Fluorescence Quartz UV Cuvette (model AT-BSM-037) has a 10mm path length, which is the international standard for spectrophotometric measurements. This allows for direct comparison with published extinction coefficients and other standardized data. Custom path lengths from 1mm to 100mm are available upon request for specialized applications.
Q: What is the correct orientation for using a Micro Fluorescence Quartz UV Cuvette?
A: For standard UV-Vis spectroscopy, position the cuvette so that the light beam passes through the clear polished sides. For fluorescence measurements, typically the excitation beam enters through one clear side, and the emission is measured at a 90° angle through another polished side. Always consult your instrument manual for specific orientation requirements.
