Semi-Micro Cuvette with Black Walls and Teflon Stopper

The semi-micro cuvette with black walls and Teflon stopper is a high-performance laboratory accessory specifically designed for precise spectrophotometric analysis involving small sample volumes and hazardous solvents. Made from high-purity black and clear quartz, this cuvette offers excellent optical performance, chemical resistance, and sample protection—making it an ideal solution for advanced research and high-sensitivity testing.

This cuvette features black quartz side walls that block stray light, significantly reducing background interference and enhancing measurement accuracy. The clear quartz windows on the front and back provide excellent transparency in both UV and visible light ranges, making the cuvette compatible with most UV-Vis spectrophotometers. This optical configuration allows researchers to achieve highly reliable results, even when working with low-concentration or light-sensitive samples.

The semi-micro design supports smaller sample volumes, helping laboratories save expensive or limited reagents without compromising accuracy. This makes it particularly suitable for applications in molecular biology, pharmaceutical testing, biochemistry, and environmental analysis, where sample availability is often limited.

One of the key features of this cuvette is the chemically resistant Teflon (PTFE) stopper, which provides a tight and secure seal. The stopper is able to prevent solvent from leakage, making the cuvette an excellent choice for handling hazardous, volatile, or corrosive solvents. This secure sealing capability not only helps maintain sample integrity but also protects users and equipment from accidental exposure or spills. The Teflon stopper is highly durable, non-reactive, and easy to clean, ensuring long-term reliability in demanding lab environments.

With a standard 10 mm path length and precision-polished optical surfaces, the cuvette ensures consistent light transmission and repeatable results. Its durable quartz construction provides superior resistance to thermal shock, chemical corrosion, and physical wear, offering a long service life even under rigorous laboratory use.

The semi-micro cuvette with black walls and Teflon stopper is ideal for use in DNA/RNA quantification, enzyme kinetics, chemical compound analysis, and toxicology studies—anywhere that requires small-volume, high-precision, and safe solvent handling.

In summary, the semi-micro cuvette with black walls and Teflon stopper is made from black and clear quartz, combining light-blocking and high-transparency properties to enhance analytical accuracy. The Teflon stopper is able to prevent solvent leakage, making this cuvette particularly suitable for testing hazardous solvents. With its combination of safety, precision, and sample efficiency, this cuvette is a dependable and essential tool for any professional laboratory.
