Description

VAOFS4 – 1.4 mL Semi-Micro Quartz Cuvette (Fused, 4 mm Width, 2 Windows, PTFE Lid)

The VAOFS4 is a high-quality fused quartz cuvette specifically designed for UV/VIS absorption spectroscopy.
With a 4 mm internal width and 10 mm optical path length, it offers a balance between sample capacity and measurement sensitivity.
The fused fabrication provides superior resistance to heat and chemicals, making it ideal for research and routine analytical applications.

Key Features

Sample volume: 1.4 mL (1400 µL) — suitable for semi-micro to standard sample sizes.
4 mm internal width: offers increased volume for versatile measurement conditions.
10 mm optical path length: standard size compatible with most spectrophotometers.
2 optical windows: optimized for accurate and stable absorption measurements.
Fused fabrication: resistant to high temperatures (up to 600 °C) and most chemicals (except HF and strong organic solvents).
Path length tolerance: ±0.06–0.08 mm.
Wavelength range: UV/VIS (190–2500 nm).

Typical Applications

UV/VIS absorption spectroscopy
Quantification of proteins, nucleic acids, and other biomolecules
Biochemical and pharmaceutical research
Environmental and materials analysis

About Fused Fabrication

Fused quartz cuvettes are manufactured by high-temperature sintering of quartz powder, ensuring:

Outstanding heat resistance — up to 600 °C.
High optical clarity and stability for precision measurements.
Chemical durability against most acids and bases (except HF and strong organic solvents such as toluene or acetone).
Typical path length tolerance: ±0.06–0.08 mm.

Usage Notes

Ideal for precise absorption spectroscopy experiments.
Best used with aqueous solutions or moderate solvents.
Not recommended for long-term storage of aggressive organic solvents.

Note: Fused quartz cuvettes offer superior thermal and chemical durability compared to bonded types, making them a reliable choice for high-precision analytical work.

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.
