Standard Cuvette with Teflon Stopper and Round Bottom

The standard cuvette with Teflon stopper and round bottom is a high-precision analytical vessel engineered for demanding spectrophotometric applications involving hazardous or sensitive solvents. Designed for compatibility with a wide range of UV-Vis spectrophotometers, this cuvette combines safety, performance, and sample-handling efficiency in one durable and thoughtfully crafted product.

Made from high-quality optical glass or quartz, this cuvette ensures excellent light transmission, chemical resistance, and durability. Quartz versions are ideal for UV-Visible spectrophotometry, offering optical clarity from 190 nm upward, while optical glass models perform reliably in the visible range, making them a practical choice for routine analysis. The precision-polished optical windows deliver consistent absorbance readings and minimal light scattering—critical for high-accuracy experiments.

This model features a round bottom design, which enhances sample mixing and reduces liquid retention, especially useful in biochemical reactions and kinetic studies. The curved interior allows for easier cleaning and better sample recovery, eliminating corners where residues may accumulate. It is particularly suited for use with magnetic stir bars during in-cuvette mixing, improving the consistency and reliability of experimental results.

A key feature of this cuvette is its secure Teflon (PTFE) stopper, which fits snugly into the top opening to provide a leak-resistant seal. The cuvette is assembled with a Teflon stopper on top, which is suitable for testing hazardous solvents. The stopper prevents evaporation and accidental leakage, protecting both the user and the surrounding equipment. Teflon is chemically inert and resistant to aggressive solvents, acids, and bases—making this cuvette a safe and durable solution for experiments involving toxic, volatile, or corrosive substances.

Available in various path lengths, this cuvette allows users to select the optimal configuration for their specific analytical needs—whether working with highly concentrated samples or low-volume microanalysis. The standard 10 mm path length is widely compatible, while alternative path lengths accommodate more specialized applications.

Ideal for use in pharmaceutical labs, environmental testing, chemical research, and life science applications, this cuvette supports a wide range of spectrophotometric techniques, including absorbance, kinetic measurements, and sample stability testing. It is a trusted choice for researchers, analysts, and quality control professionals seeking a safe, high-performance solution for solvent-sensitive testing.

In summary, the standard cuvette with Teflon stopper and round bottom is built from durable quartz or optical glass and features a rounded bottom for optimal mixing and sample handling. The Teflon stopper prevents solvent leakage, making it particularly well-suited for use with hazardous solvents. With various path lengths available, this cuvette delivers flexibility, safety, and accuracy for today’s high-demand laboratory environments.
