Description

VFOFS2 – 0.7 mL Semi-Micro Quartz Fluorescence Cuvette (Fused, 2 mm Width, 4 Windows, PTFE Lid)

The VFOFS2 is a precision fused quartz cuvette designed for UV/VIS fluorescence spectroscopy.
With a 2 mm internal width and a 10 mm optical path length, it is ideal for moderate sample volumes while maintaining excellent optical performance.
The 4-window configuration enables both excitation and emission detection, making it a versatile choice for fluorescence measurements and analytical applications.

Key Features

Sample volume: 0.7 mL (700 µL) — suitable for semi-micro fluorescence analysis.
2 mm internal width: allows accurate measurements with moderate sample usage.
10 mm optical path length: standard geometry compatible with most spectrofluorometers and spectrophotometers.
4 optical windows: designed for excitation and emission measurements.
Fused fabrication: stable at temperatures up to 600 °C and resistant to 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

Fluorescence spectroscopy
Biochemical and pharmaceutical analysis
Fluorescent dye and protein quantification
Trace-level detection and environmental testing

About Fused Fabrication

Fused quartz cuvettes are produced using high-temperature sintering of quartz powder, offering:

Outstanding heat resistance — up to 600 °C.
High optical clarity and dimensional stability for precise fluorescence measurements.
Chemical resistance to 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-sensitivity fluorescence experiments with small to moderate sample volumes.
Best used with aqueous or moderate solvents.
Not recommended for long-term storage of aggressive organic solvents.

Note: Fused quartz cuvettes offer excellent optical performance, durability, and chemical stability, making them ideal for fluorescence spectroscopy 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.
