Optical-Grade Polystyrene (PS) and PMMA Cuvettes for Spectrophotometry
VWR® Disposable Cuvettes are precision-molded, optically clear cuvettes designed for use in UV-Vis spectrophotometry, colorimetry, and photometric analysis in chemistry, life sciences, and water analysis. Available in polystyrene (PS) for visible range applications and polymethyl methacrylate (PMMA) for extended UV compatibility, these cuvettes are a convenient and cost-effective alternative to quartz glassware.
Key Features
- Optical Clarity – Recessed, scratch-free windows for high transmission and accurate readings
- Consistent Extinction Values – Tight manufacturing tolerances ensure reproducibility
- Versatile – Compatible with most polar solvents, acids, and alkalis
- Ready-to-Use – No cleaning required, minimizing contamination risk
- Resealable Packaging – Cavity-number-sorted for traceability and convenience

Applications
- Water Quality Testing – Colorimetric assays, turbidity, and chemical oxygen demand (COD)
- Molecular Biology & Biochemistry – Nucleic acid and protein quantification
- General Laboratory Use – Photometric absorbance and concentration measurements
- Clinical & Pharmaceutical Analysis – Routine QA/QC UV-Vis testing
- Educational Labs – Reliable cuvettes for student experiments
Material Guidelines
- PMMA Cuvettes: Suitable for use from 300–900 nm; resistant to alcohols, weak acids, and alkaline solutions.
- Polystyrene Cuvettes: Economical for visible light applications (340–900 nm); not recommended for use with organic solvents.
VWR® Disposable Cuvettes provide a reliable, high-quality solution for routine spectrophotometric analysis. Their precision, optical clarity, and compatibility with a wide range of aqueous and buffer systems make them ideal for research, quality control, and educational laboratories.
