Standard Fluorescence Cuvette with Stopper

The Standard Fluorescence Cuvette with Stopper is a precision-engineered laboratory vessel designed for high-sensitivity spectroscopic applications. Crafted from high-purity fused quartz, this cuvette delivers exceptional optical performance, chemical durability, and sample integrity—making it a trusted choice for fluorescence and absorbance testing in research, academic, clinical, and industrial laboratories.

A key feature of this cuvette is its four optically polished transparent walls, enabling unobstructed passage of both excitation and emission light. This design ensures maximum fluorescence signal collection with minimal distortion or loss. As such, this fused cuvette has four transparent walls, making it ideal for a variety of fluorescence-based analytical techniques that require high precision and reliability.

High-Quality Fused Quartz Construction

The cuvette is constructed from fused quartz, a material known for its superior transparency in the ultraviolet (UV), visible, and near-infrared (NIR) regions. Quartz provides high thermal stability, excellent chemical resistance, and outstanding optical clarity down to 190 nm, which is critical for UV fluorescence applications.

Compared to standard optical glass or plastic cuvettes, fused quartz offers much lower fluorescence background, allowing for more sensitive measurements and better signal-to-noise ratios—especially important when working with low-concentration samples or weakly fluorescent compounds.

Enhanced Sealing with Teflon Stopper

What sets this cuvette apart is its precision-fit Teflon stopper, designed to tightly seal the cuvette opening for superior sample protection. The stopper plays a critical role in maintaining sample integrity during sensitive measurements:

This fused cuvette has four transparent walls, its Teflon stopper can prevent solvent from the leakage and also strength corrosion resistance.

The Teflon (PTFE) stopper resists chemical attack from aggressive solvents and reagents, making it ideal for use with acids, bases, and organic compounds. It also helps to prevent sample evaporation or oxidation, which can alter the accuracy of your test results—particularly important for long-duration experiments or reactions involving volatile components.

In addition, the stopper ensures a leak-proof seal, offering peace of mind during handling, transportation, or storage of the sample within the cuvette.

Applications

The Standard Fluorescence Cuvette with Stopper is designed for use in a broad range of scientific applications, including:

• Fluorescence spectroscopy

• UV-Vis absorbance analysis

• Photoluminescence studies

• Molecular biology and biochemical assays

• Protein and DNA quantification

• Kinetic enzyme reactions

• Environmental sample testing

• Quality control in pharmaceutical and chemical industries

Whether you’re working in a controlled lab environment or a field-testing situation, this cuvette offers a versatile and durable solution for precise optical analysis.

Compatibility and Specifications

This cuvette features the standard 10 mm optical pathlength, making it compatible with the vast majority of commercial spectrophotometers and fluorometers. The precise dimensions, smooth polished surfaces, and consistent wall thickness help ensure repeatable, accurate measurements across different instruments.

To maintain the cuvette’s performance, it should be handled with care—always use gloves and grip it by the frosted sides to avoid leaving smudges on the optical windows. After use, clean the cuvette with appropriate solvents and dry with a lint-free cloth. Its robust construction allows for repeated use, offering long-term value and reduced waste compared to disposable alternatives.
