Description

VAOF45 Fused Quartz Macro Cuvette is a 7 ml capacity large-format cuvette designed for absorption spectroscopy with a 5 mm optical path length. With its wide 45 × 45 mm clear wall design and fused quartz construction, this model is well suited for applications that require stable signal acquisition from larger sample volumes.

Its sturdy structure and precision manufacturing make it ideal for laboratories that use macro cuvettes for routine UV/VIS analysis, method development, or process monitoring.

Key Features

5 mm optical path — optimized for medium-to-high concentration samples.
7 ml capacity — suitable for macro sample volumes and stable measurements.
Wide clear walls — provides excellent light transmission and signal stability.
Fused quartz construction — ensures UV transparency, high thermal stability, and chemical resistance.
Wavelength range: 190–2500 nm — compatible with UV/VIS/NIR instruments.

Typical Applications

Standard and routine UV/VIS absorption measurements
Biochemical and chemical analysis with macro sample volumes
Process control and method development
Environmental and industrial sample testing
Custom instrument integration

Fused Fabrication Notes

Fused quartz allows high optical transmission and stable dimensions under high temperatures (up to 600 °C).
Not suitable for HF or aggressive organic solvents (e.g., toluene, acetone).
Powder seams may discolor over time but do not affect optical performance.
Dimensional 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.
