Description

VCOF20Q Fused Quartz Cuvette is a precision-engineered 5-window cuvette with a 20 mm optical path length and 3 ml sample volume.
This custom-designed cell is optimized for fluorescence spectroscopy, particularly in applications where a low profile and high optical clarity are required.

Key Features

20 mm optical path — improves measurement sensitivity for fluorescence and absorbance experiments.
5-window configuration — ideal for side and right-angle fluorescence detection.
Ultra-low height (8.5 mm) — reduces sample volume while maintaining standard optical path length, perfect for precious or limited samples.
Fused quartz construction — withstands high temperatures (up to 600 °C) and offers broad chemical compatibility, except with HF and certain strong organic solvents.
High transmittance from 190–2500 nm for UV/VIS/NIR measurements.

Typical Applications

Fluorescence and absorbance spectroscopy with limited sample volume.
Biochemical and molecular assays with side detection.
High-sensitivity analytical work in environmental and life science research.
Custom instrument integration and micro-sample testing.

Fused Fabrication Notes

Can be heated to 600 °C without deformation.
Assembled with quartz powder — minor discoloration may occur when exposed to strong dyes or solvents.
Not intended for long-term sample storage.
Not compatible with HF, toluene, acetone, or other strong organic solvents, as these may shorten the cuvette 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.
