Description

VFFL20N Fused Quartz Cuvette is a 4-window cuvette with a 20 mm optical path length and 8 ml volume.
It is made using fused fabrication, providing excellent thermal resistance and broad chemical compatibility, ideal for fluorescence and absorbance measurements that require durability and stable performance.

Key Features

20 mm optical path — enhances absorbance signal intensity and improves sensitivity for fluorescence detection.
4-window design — suitable for both transmission and right-angle fluorescence measurements.
Fused quartz construction — withstands high temperatures (up to 600 °C) and most chemicals, except HF and some strong organic solvents.
Open-top format — easy sample handling and cleaning, ideal for non-volatile solutions and quick experiments.
High transmission from 190–2500 nm for UV/VIS/NIR measurements.

Typical Applications

Fluorescence and absorbance spectroscopy across UV/VIS/NIR.
Photochemical experiments requiring temperature stability.
Environmental, chemical, and materials analysis.
Routine measurements and R&D lab applications.

Fused Fabrication Notes

Can be heated to 600 °C without deformation.
Assembled with quartz powder — slight surface coloration may occur with certain dyes or strong solvents.
Not recommended for long-term storage of samples.
Not compatible with HF, toluene, acetone, and other strong organic solvents — these will shorten the cuvette’s lifespan.

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.
