(VFFL30N) 27 mL Large Cuvette, 4 Windows, No Cover, Fused, Lightpath 30mm, 32x34x34 mm

Description VFFL30N Large Fused Quartz Cuvette is a 4-window cuvette with a 30 mm optical path length and a 27 ml volume, engineered for high-sensitivity fluorescence and UV/VIS spectroscopy. The 4-window structure allows side detection for fluorescence while maintaining excellent optical transmission. Key Features 30 mm optical path — enhances light absorption and fluorescence signal for trace-level detection. 4-window design — optimized for side excitation and detection in fluorescence measurements. 27 ml capacity — suitable for large-volume samples and photochemical experiments. Fused quartz fabrication — ensures excellent UV transmission, heat resistance up to 600 °C, and minimal signal distortion. Wide wavelength range 190–2500 nm covering UV, VIS, and NIR applications. Typical Applications Fluorescence spectroscopy requiring side excitation and detection. Environmental and chemical analysis where high sensitivity is essential. Photochemical, kinetic, or absorption studies with larger sample volumes. Research and calibration requiring stable and repeatable measurements. Fused Fabrication Notes Made from fused quartz powder with minimal bonding lines — excellent thermal stability and optical quality. Gaps may discolor over time; not recommended for long-term sample storage. Not suitable for HF, toluene, acetone, or other strong organic solvents. High precision and low autofluorescence for demanding applications.

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.
