Standard Fluorescence Cuvette with Lid
The Standard Fluorescence Cuvette with Lid is a high-performance optical vessel designed for demanding fluorescence and absorbance measurements in research, analytical, and industrial laboratories. Engineered with precision and crafted from high-quality fused quartz, this cuvette offers superior optical clarity, excellent chemical resistance, and long-term durability. It is an ideal choice for scientists and technicians seeking accurate, reproducible results across a range of spectroscopic applications.
One of the defining features of this cuvette is its four optically polished, transparent walls, which provide unmatched transmission across the UV, visible, and near-infrared spectra. This design is essential for fluorescence spectroscopy, where both the excitation and emission light paths must pass through the sample with minimal interference or loss. As such, this fused cuvette has four transparent walls, which is suitable for fluorescence test, enabling accurate detection of low-intensity fluorescence signals with high sensitivity and resolution.
Material and Build Quality
The cuvette is made from fused quartz, a material widely recognized for its exceptional purity and optical properties. Unlike glass or plastic alternatives, fused quartz offers superior UV transparency, allowing light transmission down to approximately 190 nm—critical for applications that require analysis in the UV range. It also withstands extreme temperature changes, resists corrosion by acidic or basic solutions, and remains stable under prolonged exposure to radiation.
Each cuvette is manufactured with tight dimensional tolerances to ensure compatibility with a wide range of laboratory spectrometers and fluorometers. The polished surfaces are precisely aligned for minimal light scattering, while the uniform wall thickness guarantees consistent pathlength (typically 10 mm), enhancing the reliability of quantitative measurements.
Lid Design for Sample Integrity
The cuvette comes with a fitted lid, which provides multiple practical advantages. First, it helps to prevent contamination from dust or airborne particles, preserving the purity of the sample. Second, it reduces evaporation, making it ideal for long-duration experiments or sensitive biological samples. Third, the lid helps minimize oxygen exposure, which can be crucial for reactions sensitive to oxidation or for maintaining sample stability over time.
This added protection is especially valuable when working with volatile solvents, biological samples, or small-volume assays where every microliter matters. The lid also reduces the risk of spills or accidental loss of sample during handling or measurement.

Compatibility and Care
This cuvette is compatible with most standard spectrophotometers and fluorescence instruments that accept 10 mm pathlength cuvettes. For best results, always handle cuvettes by the frosted sides to avoid fingerprints on the optical surfaces. Clean thoroughly with compatible solvents and soft lint-free cloths to maintain optimal performance.
Due to its durable construction, the cuvette can be reused many times if handled and cleaned properly, offering excellent value over disposable alternatives.
