Description

VAOF40 Fused Quartz Long Pathlength Cuvette is a 40 mm standard absorption cuvette equipped with a PTFE lid.
This cuvette provides extended pathlength for higher detection sensitivity in UV/VIS spectroscopy.

Key Features

40 mm optical pathlength — enhances absorbance signals, improving detection of trace or low-concentration samples.
PTFE lid — prevents sample evaporation and contamination during extended measurement runs.
Fused quartz fabrication — excellent UV transparency (190–2500 nm), high thermal resistance (up to 600 °C), and strong chemical durability (except HF and some organic solvents).
Round base design — ensures secure fit with standard spectrophotometer holders.
Reliable and stable for routine analytical and research use.

Typical Applications

Trace analysis and low-concentration measurements
Environmental and water quality monitoring
Pharmaceutical and biochemical R&D
General UV/VIS absorption spectroscopy

Fused Fabrication Notes

Excellent UV/VIS optical performance and heat resistance
Pathlength tolerance: ±0.06 – 0.08 mm
Not recommended for HF, toluene, acetone, or aggressive solvents

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.
