Description

V5ML20P Large Quartz Cuvette is a 5-window molded quartz cuvette with a 20 mm optical path length and 8 ml volume.
It features a PTFE cover, making it suitable for general fluorescence and absorbance experiments that benefit from basic evaporation control while keeping sample handling convenient.

Key Features

20 mm optical path — ideal for enhanced absorbance and fluorescence measurements with increased signal strength.
5-window design — enables multiple measurement geometries, including side fluorescence detection.
8 ml capacity — fits small to mid-volume analytical and photochemical experiments.
Molded quartz construction — offers excellent optical quality and dimensional precision.
PTFE cover — helps minimize evaporation and dust contamination without completely isolating from air.

Typical Applications

Fluorescence and absorbance spectroscopy in the UV/VIS/NIR region.
Photochemical and kinetic studies with moderate volume.
Environmental, chemical, and materials research requiring stable measurement geometry.
Routine laboratory measurements where good repeatability and optical clarity are required.

Molded Fabrication Notes

High dimensional precision and smooth optical surfaces minimize stray light and scattering.
PTFE lid is not oxygen-tight — for oxygen-sensitive samples, a fully sealed solution is recommended.
Excellent transmission across 190–2500 nm wavelength range.
Not suitable for highly aggressive solvents such as HF, toluene, or acetone.

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.
