Semi-Micro Cuvette with Black Walls and Lid
The semi-micro cuvette with black walls and lid is a specialized laboratory tool designed for precise spectrophotometric measurements using small sample volumes. Manufactured from high-purity black and clear quartz, this cuvette offers outstanding performance in both UV and visible light ranges, making it a versatile and valuable choice for laboratories focused on accuracy, efficiency, and sample conservation.
This cuvette features black quartz side walls combined with clear quartz optical windows, a design that offers two key advantages. First, the black walls help partly block stray light, reducing background interference and improving signal-to-noise ratio during spectrophotometric analysis. This makes the cuvette especially suitable for low-concentration or low-absorbance samples, where even minor optical inconsistencies can affect results. Second, the semi-micro format is specifically engineered to save solvent, requiring a reduced sample volume—ideal for precious or limited samples often used in life sciences, pharmaceuticals, and biochemical research.
Equipped with a chemically resistant lid, typically made from PTFE (Teflon), the cuvette ensures that samples remain sealed and stable during analysis. The lid protects against solvent evaporation, external contamination, and accidental spills, while also supporting safe handling of volatile or sensitive substances. This added sealing capability makes it suitable for kinetic studies, temperature-sensitive measurements, and long-duration experiments.
With a standard 10 mm path length and precision-polished optical windows, the cuvette guarantees reliable and consistent results across various spectrophotometers. Its durable quartz construction offers superior optical clarity and excellent resistance to harsh chemicals and high temperatures, ensuring longevity and consistent performance even in demanding environments.
The semi-micro cuvette with black walls and lid is ideal for a wide range of applications, including nucleic acid and protein quantification, enzymatic kinetics, photometric analysis of small-volume reagents, and testing of expensive or scarce compounds. It is an excellent choice for research institutions, pharmaceutical labs, and quality control settings that prioritize both accuracy and resource efficiency.
In summary, the semi-micro cuvette with black walls and lid is made of black and clear quartz, allowing it to partly avoid stray light and save solvent during testing. With high optical precision, a protective lid, and low-volume efficiency, this cuvette delivers exceptional performance for sensitive and small-scale spectrophotometric measurements—making it an indispensable tool in any modern laboratory.
