Description

VAOFS3 – 1.05 mL Semi-Micro Quartz Cuvette (Fused, 3 mm Width, 2 Windows, PTFE Lid)

The VAOFS3 is a high-quality fused quartz cuvette designed for UV/VIS absorption spectroscopy.
With a 3 mm internal width and 10 mm optical path length, it allows for flexible sample handling — ideal for medium-volume samples requiring stable and accurate optical measurements.
The fused fabrication ensures exceptional resistance to heat and most chemicals, making it suitable for demanding analytical and research applications.

Key Features

Sample volume: 1.05 mL (1050 µL) — suitable for semi-micro to medium-volume analysis.
3 mm internal width: ideal for moderate concentration samples with reduced sample loss.
10 mm optical path length: standard geometry, compatible with most spectrophotometers.
2 optical windows: optimized for precise absorption measurements.
Fused fabrication: heat resistant up to 600 °C and chemically stable (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
Biochemical and pharmaceutical assays
Protein and nucleic acid analysis
Environmental and material testing

About Fused Fabrication

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

Excellent thermal resistance — up to 600 °C.
High optical clarity and measurement stability.
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 high-precision absorption measurements.
Best suited for aqueous solutions and moderate solvents.
Not recommended for long-term storage of aggressive organic solvents.

Note: Compared with bonded cuvettes, fused quartz cuvettes offer superior chemical resistance and durability, making them well-suited for demanding analytical applications.

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.
