(V5ML20N) 8 mL Large Cuvette, 5 Windows, No Cover, Molded, Lightpath 20mm, 22x24x24 mm

Description V5ML20N Large Quartz Cuvette is a 5-window molded quartz cuvette with a 20 mm optical path length and 8 ml volume. This open-top design is ideal for general fluorescence and absorbance measurements where a cover is not required, making it convenient for fast sample handling and cleaning. Key Features 20 mm optical path — increases absorbance signal intensity and enhances fluorescence detection. 5-window design — supports multiple measurement geometries, including standard absorbance and side fluorescence detection. 8 ml volume — suitable for moderate-volume applications and routine experiments. Open-top format — easy sample addition, rinsing, and cleaning, perfect for quick measurement workflows. Molded quartz fabrication — provides excellent optical clarity and dimensional precision. Typical Applications Fluorescence and absorbance spectroscopy in UV/VIS/NIR ranges. Photochemical and kinetic studies where easy access to the sample is advantageous. Environmental and chemical testing in R&D or academic labs. Routine laboratory use with standard instrument holders. Molded Fabrication Notes High dimensional precision ensures stable measurement positioning and minimal signal deviation. Open-top design does not protect against evaporation — best suited for rapid measurements or stable samples. Excellent transmission from 190–2500 nm. Not compatible with HF, toluene, acetone, or other strong organic solvents.

IR or Glass material is not included. Why QVARZ Cuvettes and Cells?QVARZ is world-renowned as the producer of premium quartz cuvettes. Over fifteen years of experience manufacturing quartz cuvettes ensures that every QVARZ cuvettes are manufactured to the most exacting standards for reproducible results. Spectrophotometry cuvettes - Most spectrophotometry applications in the visible and UV ranges benefit from QVARZ spectrophotometry cuvettes. Our cuvettes made of fused quartz material deliver precise and reliable readings even at wavelengths as low as 190 nm. QVARZ cuvettes are compatible with most spectrophotometers and photometers with standard 0.2 - 100 mm path lengths. Fluorometry cuvettes - QVARZ brings two decades of experience molding high-quality spectrophotometry cuvettes to new four-sided clear cuvettes for fluorometry. Available in standard quartz material with ultra-low auto-fluorescence for the highest precision measurements. Protective packaging - QVARZ cuvettes are encased in dust-free, low scratching expanded polystyrene packaging. This ensures that premium cuvettes arrive in the laboratory ina the same pristine condition they were in at the factory, with optical quality windows and free of contaminants.  Volumes for most purposes - Our cuvettes are available in a variety of ranges from macro to macro semi-micro sizes to respond to the needs of most scientific applications. We are also able to customize sample volume to deliver consistent, accurate findings. Perform consistently - QVARZ Cuvettes are constructed from high-quality fused quartz materials and are grouped by manufacturing mold cavities to ensure the lowest fluctuation in extinction coefficient.
