(VAFL30N) 43 mL Large Cuvette, 2 Windows, No Cover, Fused, Lightpath 30mm, 50x34x34 mm

Description VAFL30N Fused Quartz Large Cuvette is a 2-window, 30 mm path length cuvette with a large 43 ml internal volume. It is designed for applications requiring higher sample capacity and extended optical path for increased sensitivity, particularly in UV/VIS absorbance spectroscopy. The cuvette is fabricated with fused quartz for excellent chemical and thermal resistance, making it suitable for demanding analytical environments. Key Features 30 mm optical path length — increases absorbance sensitivity, ideal for trace analysis and low-concentration samples. 2-window design — optimized for transmission and absorbance measurements with minimal signal loss. Fused fabrication — offers high temperature resistance and chemical durability for long-term use. Large 43 ml capacity — allows for bulk sampling and extended measurement runs. Wide spectral range — 190 – 2500 nm, suitable for UV, visible, and NIR applications. Typical Applications UV/VIS absorbance spectroscopy. Trace-level detection with extended path length. Environmental, chemical, and industrial monitoring. Experiments requiring large sample volume and stable optical alignment. Fused Fabrication Notes High temperature resistance up to 600 °C (1112 °F). Excellent resistance to most acids, bases, and solvents (excluding HF, toluene, acetone, and other aggressive organics). Powder seams may discolor with long-term storage; not intended for extended sample containment. No cover — suitable for open-top measurements or setups with external sealing mechanisms.

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.
