Standard Cuvette with Teflon Stopper and Round Bottom

The standard cuvette with Teflon stopper and round bottom is a high-quality laboratory vessel designed for accurate spectrophotometric analysis, especially when working with hazardous solvents. This cuvette is engineered to meet the rigorous demands of modern laboratories by offering excellent chemical resistance, enhanced safety features, and optimized sample handling for a wide range of testing applications.

Manufactured from high-purity quartz or premium optical glass, the cuvette delivers superior optical performance across both UV and visible light spectrums. Quartz options provide excellent light transmission down to 190 nm, making them ideal for UV-Vis analysis, while optical glass versions are well-suited for visible-range measurements. Each cuvette features precision-polished optical windows to ensure accurate, reproducible results with minimal light distortion.

One of the key structural advantages of this model is its round bottom design, which supports thorough sample mixing and complete drainage. The curved base is ideal for use with magnetic stir bars, allowing for better reaction uniformity in kinetic studies or enzyme assays. It also helps reduce residual sample retention, simplifying the cleaning process and minimizing cross-contamination between uses.

The cuvette is equipped with a high-quality Teflon (PTFE) stopper that fits securely into the top opening. The stopper is able to prevent solvent from leakage, making this cuvette particularly suitable for handling hazardous, volatile, or corrosive solvents. The chemically inert properties of Teflon provide outstanding resistance to acids, bases, and organic solvents, ensuring long-lasting performance even in aggressive laboratory environments. In addition to preventing spills and evaporation, the stopper also helps maintain sample integrity over time.

With a standard 10 mm optical path length, the cuvette is compatible with most UV-Vis spectrophotometers, making it a versatile choice for a wide range of analytical procedures. Whether used in pharmaceutical research, chemical testing, environmental monitoring, or academic studies, this cuvette offers the reliability and safety needed for precise, small-volume analysis.

This model is ideal for experiments where safety is a top priority and where hazardous solvents are frequently used. It enables researchers and technicians to conduct high-sensitivity measurements with confidence, knowing that their samples are well-contained and protected.

In summary, the standard cuvette with Teflon stopper and round bottom is made from durable quartz or optical glass, featuring a curved base for optimal mixing and easy cleaning. The Teflon stopper is able to prevent solvent from the leakage, making this cuvette particularly suitable for testing hazardous solvents. With its robust construction, secure sealing, and optical precision, it is an essential tool for any laboratory that values safety, efficiency, and accuracy in spectrophotometric analysis.
