Micro Cuvette with Black Walls and Lid

The micro cuvette with black walls and lid is a specialized analytical tool designed for ultra-low volume spectrophotometric measurements, where both accuracy and sample conservation are critical. Engineered for compatibility with most UV-Vis spectrophotometers, this cuvette offers outstanding optical clarity, chemical durability, and advanced light control—making it an ideal choice for cutting-edge laboratories across life sciences, pharmaceuticals, environmental testing, and beyond.

Constructed from black and clear quartz, this cuvette delivers high-performance optical characteristics across a broad wavelength range. The black quartz side walls are specifically designed to partly avoid stray light, minimizing background interference and maximizing signal precision. The clear quartz optical faces provide exceptional transmission down to the deep UV range (as low as 190 nm), enabling accurate measurements of nucleic acids, proteins, and other biomolecules in even the smallest sample volumes.

As a micro cuvette, this design is optimized for extremely limited sample quantities—perfect for situations where reagents are expensive, rare, or difficult to obtain. The small internal chamber ensures consistent optical path length while dramatically reducing solvent and sample consumption, a key benefit for biotech, clinical, and R&D labs seeking to maximize efficiency without compromising on accuracy.

Equipped with a PTFE (Teflon) lid, the cuvette adds another layer of functionality and safety. The lid helps to prevent sample evaporation, contamination, and accidental spills during handling or extended measurements. This feature is especially useful for temperature-sensitive experiments or kinetic studies that require stable sample conditions over time. The chemically resistant Teflon material is compatible with a wide range of solvents and reagents, ensuring reliable performance even under harsh laboratory conditions.

The micro cuvette’s compact size and high-precision finish, including polished optical windows and uniform wall thickness, ensure dependable, reproducible readings in every use. A standard 10 mm path length maintains consistency with most spectrophotometric protocols, and its compatibility with automated cuvette holders adds convenience to high-throughput workflows.

This cuvette is ideal for DNA/RNA quantification, protein assays, photometric analysis of high-value compounds, and advanced research where sample size is a limiting factor. It’s also widely used in pharmaceutical quality control, molecular diagnostics, and academic research.

In summary, the micro cuvette with black walls and lid is made of black and clear quartz, allowing it to partly avoid stray light and save solvent, while offering superior optical performance and sample protection. Whether you are analyzing microliter volumes of a rare compound or conducting sensitive UV-Vis experiments, this cuvette delivers the accuracy, durability, and efficiency that modern laboratories demand.
