Description

VAFL50N Fused Quartz Cuvette is a 2-window large-capacity cuvette designed for high-sensitivity absorbance measurements with a 50 mm optical path length and 132 ml volume.
Made from high-purity fused quartz, it is well suited for trace detection, environmental monitoring, and analytical applications that require long path lengths to enhance absorbance signals.

Key Features

50 mm optical path — dramatically improves sensitivity for low-concentration measurements, making weak signals measurable.
2-window design — ideal for absorbance, transmission, and spectrophotometric testing.
Fused quartz construction — can withstand high temperatures (up to 600 °C) and most chemicals (except HF, toluene, acetone, and other strong organics).
Large 132 ml capacity — supports bulk sample testing and industrial or environmental analysis.
High transmission across the 190–2500 nm wavelength range, suitable for UV/VIS/NIR applications.

Typical Applications

Trace analysis and low-concentration absorbance measurements.
Water quality and environmental monitoring (e.g., nitrates, phosphates, heavy metals).
Industrial process and chemical analysis with large sample volumes.
UV-VIS spectroscopy in research and production environments.

Fused Fabrication Notes

Can be heated to 600 °C without deformation.
Assembled with quartz powder — slight surface coloration may occur with certain dyes or aggressive solvents.
Not suitable for long-term sample storage.
Not compatible with HF, toluene, acetone, and other strong organic solvents — using these will shorten 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.
