Micro Cuvette with Black Walls and Stopper

The micro cuvette with black walls and stopper is a premium-grade laboratory tool designed for ultra-low volume spectrophotometric analysis, particularly in environments where safety, precision, and sample conservation are essential. Engineered for compatibility with most UV-Vis spectrophotometers, this cuvette combines advanced material design with a secure sealing system to deliver exceptional performance, even under demanding laboratory conditions.

Made from black and clear quartz, the cuvette ensures superior optical clarity and chemical resistance across a broad wavelength range. The black quartz side walls are designed to partly avoid stray light, significantly reducing background interference and enhancing the accuracy of absorbance measurements. The clear quartz optical windows allow excellent transmission in both UV and visible light ranges, enabling precise analysis down to 190 nm — ideal for DNA/RNA quantification, protein assays, and other sensitive biochemical tests.

With a micro-volume capacity, this cuvette is perfect for applications involving scarce or expensive reagents. It allows researchers to save solvent and reduce sample usage without sacrificing data quality, making it especially useful in molecular biology, drug development, clinical diagnostics, and academic research. Despite its compact internal volume, it maintains a standard 10 mm optical path length to ensure compatibility with a wide range of spectrophotometric protocols and instruments.

A key feature of this cuvette is its precision-fitted PTFE (Teflon) stopper, which provides a tight and reliable seal. The stopper is able to prevent solvent from leakage, making the cuvette particularly well-suited for testing hazardous, volatile, or corrosive solvents. This secure seal helps protect users and equipment, while also maintaining the integrity of sensitive samples by preventing evaporation or contamination. The Teflon material is chemically inert and highly resistant to degradation, ensuring long-term durability and safe performance with a wide range of solvents.

Each micro cuvette is crafted with high-precision polishing and strict dimensional control to ensure consistent light transmission and minimal sample loss. Its durable quartz body withstands harsh chemicals and high temperatures, making it a reliable choice for both routine analysis and specialized research.

Ideal for high-sensitivity testing, kinetic studies, and micro-volume photometric assays, this cuvette is widely used in fields such as pharmaceutical R&D, biotechnology, toxicology, and advanced academic laboratories.

In summary, the micro cuvette with black walls and stopper is made from black and clear quartz to offer enhanced light control and sample efficiency. The stopper is able to prevent solvent leakage, making this cuvette an excellent choice for hazardous solvent testing and precision spectrophotometric applications involving limited sample volumes. Combining safety, reliability, and analytical performance, it’s an essential tool for modern laboratory workflows.
