Standard Cuvette with Lid and Flat Bottom

The Standard Cuvette with Lid and Flat Bottom is an essential tool for laboratories that demand precision, consistency, and durability in their spectroscopic analysis. Engineered with high-quality materials and designed to meet a wide range of application needs, this cuvette delivers reliable results for professionals in chemistry, biology, environmental science, and more.

Material and Construction

This cuvette is available in premium optical glass or high-grade quartz, depending on your application requirements. Optical glass is ideal for visible light applications (320–2,500 nm), offering excellent clarity, precision, and cost-efficiency. For experiments requiring UV transparency, the quartz version is recommended, supporting a much broader wavelength range (190–2,500 nm) without compromising performance.

The cuvette features a flat bottom design, ensuring it sits securely and evenly within a spectrophotometer holder. This design enhances measurement accuracy by maintaining proper alignment in the light path and ensuring consistent sample thickness throughout the optical window.

The matched Teflon (PTFE) lid provides several important benefits. It is chemically inert and resistant to most solvents and acids, making it suitable for even the most aggressive chemical environments. The lid not only prevents solvent evaporation and leakage, which is critical in long-term or volatile sample testing, but also enhances the cuvette’s corrosion resistance, protecting both the sample and the equipment. The snug fit of the lid minimizes contamination risk and maintains sample integrity during handling and storage.

Compatibility

The standard cuvette with lid is designed to be compatible with a wide range of spectrophotometers, making it a versatile choice for most laboratory settings. Its standard dimensions (typically 10 mm path length and 12.5 mm outer width) ensure a seamless fit in cuvette holders used in UV-Vis spectrophotometry, fluorometry, and other optical measurement systems.

Whether you’re using a single-beam, double-beam, or diode-array spectrophotometer, this cuvette is engineered to meet the performance demands of modern analytical instruments.

Applications

This cuvette is ideal for a broad spectrum of scientific applications, including:

• UV-Vis Spectroscopy: Quantitative and qualitative analysis of chemical compounds.

• DNA/RNA and Protein Quantification: In molecular biology workflows requiring precise absorbance measurements.

• Environmental Testing: Monitoring pollutants and chemical residues in water, air, or soil samples.

• Pharmaceutical and Chemical Analysis: Quality control and compound characterization.

• Educational Laboratories: Teaching spectroscopy techniques in academic settings.

Thanks to its superior build and material options, the cuvette performs reliably even in complex or sensitive assays where precision and sample protection are critical.
