Description

VAOFB20 Fused Quartz Absorption Cuvette is a 2-window cuvette with a 10 mm optical path length and a 20 ml volume. It features a wide clear wall design, making it an excellent choice for UV/VIS absorbance measurements that require high chemical resistance and stable light transmission. Fused fabrication provides superior thermal durability and resistance to most acids and bases, making it suitable for demanding research and analytical environments.

Key Features

10 mm optical path length — the standard for UV/VIS absorbance measurements, ensuring high reproducibility.
2-window design — optimized for straight-beam spectroscopy and stable light transmission.
Fused fabrication — excellent thermal resistance (up to 600 °C) and chemical durability for most acidic and basic solutions.
Wide wall geometry — supports stable optical performance with low background interference.
Broad wavelength range — 190 – 2500 nm, suitable for UV/VIS and NIR applications.

Typical Applications

UV/VIS absorbance and transmission studies.
Protein and nucleic acid quantification at 260/280 nm.
Environmental pollutant analysis (e.g., nitrates, phosphates).
High-precision laboratory and QC testing.
Applications requiring chemical resistance and thermal stability.

Fused Fabrication Notes

Fused fabrication provides excellent thermal and chemical resistance.
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 path length tolerance is ±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.
