Description

VAOF9 Fused Quartz Absorption Cuvette is a 2-window cuvette with a 9 ml capacity and a 5 mm optical path length. This model features a wide-square geometry (45 × 45 mm), making it a typical example of customized cuvette design for specialized analytical setups and OEM instrument integration.

Unlike standard cuvettes, VAOF9 provides greater flexibility in matching non-standard sample holders, larger beam areas, or instrument-specific optical alignments. Its fused quartz construction ensures excellent optical clarity and chemical stability, making it ideal for a variety of advanced UV/VIS analytical tasks.

Key Features

Customized geometry (45 × 45 mm) — designed for special instrument interfaces and unique analytical requirements.
5 mm optical path — standard short path suitable for medium and high concentration samples.
9 ml sample capacity — ideal for larger-volume testing environments.
Fused quartz construction — excellent UV transmission, thermal stability, and chemical durability.
Broad wavelength range: 190–2500 nm — compatible with UV/VIS and NIR spectrophotometers.

Typical Applications

OEM or instrument-specific integration
Environmental and industrial process monitoring
Biochemical and pharmaceutical analysis
Custom spectroscopy setups
R&D requiring non-standard cuvette dimensions

Fused Fabrication Notes

Fused quartz offers outstanding transmission, heat resistance up to 600 °C, and broad chemical compatibility.
Not suitable for hydrofluoric acid (HF) or strong organic solvents like toluene and acetone.
Powder seams may discolor over time but do not affect optical performance.
Typical 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.
