Description

VFOF08 Dual-Pathlength Fused Quartz Cuvette is a precision 4-window cell designed for fluorescence and absorbance measurements requiring flexibility and optical accuracy.
It features dual optical paths (8 mm and 20 mm), allowing users to switch between high-sensitivity and high-concentration measurements without changing cuvettes.
Made from high-purity fused quartz, it provides excellent UV transmission down to 190 nm and thermal stability up to 600 °C.

Key Features

Dual path lengths (8 mm / 20 mm) — ideal for both concentrated and dilute samples in a single cuvette.
Four polished windows for both excitation and emission detection, suitable for fluorescence spectroscopy.
High-purity fused quartz ensures wide UV/VIS/NIR transmission (190 – 2500 nm).
Heat-resistant up to 600 °C, suitable for thermal or photochemical experiments.
Excellent chemical durability — avoid HF, toluene, acetone, or other strong organic solvents that can shorten service life.

Typical Applications

Fluorescence spectroscopy with dual-path configuration.
Absorbance and transmission studies requiring different optical paths.
Photoluminescence and emission intensity calibration.
High-temperature or UV-sensitive chemical analysis.

Fused Fabrication Notes

Fused fabrication allows the cuvette to be heated up to 600 °C (1112 °F).
Assembled with quartz powder — fine seams may slightly color with repeated use; not recommended for long-term sample storage.
Avoid hydrofluoric acid (HF), toluene, acetone, and other strong organic solvents to preserve optical integrity and extend lifetime.
Rinse with neutral detergent or distilled water and dry gently after each use.

QVARZ Cuvettes Transmission Characteristics The following table is our cuvettes and cells made of quartz material suitable for wavelength from 190nm to 2500nm and depicts the percentage transmission for the material. 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. Customization - Custom cuvettes and cells are encouraged and available upon request; mechanical drawings with specifications and tolerances are prerequisites. Awesome pricing and flexibility on small quantities.
