(V5ML20Q) 8 mL Large Cuvette, 5 Windows, Quartz Cover, Molded, Lightpath 20mm, 22x24x24 mm

Description V5ML20Q Large Quartz Cuvette is a 5-window molded quartz cuvette with a 20 mm optical path length and 8 ml volume. It is equipped with a quartz cover, offering better chemical compatibility and sample protection than PTFE lids, making it ideal for advanced fluorescence and absorbance measurements. Key Features 20 mm optical path — enhances absorbance sensitivity and improves fluorescence detection signal. 5-window design — allows multiple measurement geometries, including side fluorescence detection and front-face illumination. 8 ml capacity — suitable for moderate volume photochemical and analytical experiments. Quartz cover — offers higher chemical resistance and improved optical compatibility compared with PTFE covers. Molded quartz fabrication — ensures excellent dimensional accuracy and optical clarity. Typical Applications High-sensitivity fluorescence and absorbance spectroscopy in UV/VIS/NIR ranges. Photochemical and kinetic studies with controlled sample conditions. Environmental, chemical, and material analysis requiring stable measurement geometry. Advanced R&D laboratories demanding high optical precision. Molded Fabrication Notes High dimensional accuracy and smooth optical surfaces reduce stray light and scattering. Quartz cover provides better sealing and chemical durability than PTFE but is not completely airtight. Excellent transmission across 190–2500 nm wavelength range. Not compatible with HF or certain strong organic solvents such as toluene and acetone.

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.
