Description

VAOF100 Fused Quartz Long Pathlength Cuvette is a 100 mm standard absorption cuvette designed for high-sensitivity UV/VIS measurements.
With its extended optical path length and PTFE lid, it is ideal for trace-level and low-concentration analysis requiring enhanced signal strength.

Key Features

100 mm long pathlength — amplifies absorbance signals, increasing sensitivity for ultra-low concentration detection.
PTFE lid — reduces evaporation and sample contamination, suitable for longer measurement periods.
Fused quartz fabrication — ensures high UV/VIS transmission (190–2500 nm) and reliable performance at elevated temperatures (up to 600 °C).
Round base design — fits standard holders securely and maintains optical alignment.
High manufacturing precision for stable, repeatable measurements.

Typical Applications

Trace chemical and environmental analysis
Water quality testing and pollutant monitoring
Low concentration absorption assays
Biochemical, clinical, and pharmaceutical R&D

Fused Fabrication Notes

Excellent UV transparency and thermal resistance.
Not suitable for hydrofluoric acid (HF) or certain strong organic solvents.
Typical light path tolerance: ±0.06 – 0.08 mm.

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.
