Description

VFOFS5 – 1.75 mL Semi-Micro Quartz Fluorescence Cuvette (Fused, 5 mm Width, 4 Windows, PTFE Lid)

The VFOFS5 is a high-performance fused quartz cuvette designed for UV/VIS fluorescence spectroscopy.
With a 5 mm internal width and a 10 mm optical path length, it is ideal for experiments that require larger sample volumes without compromising signal quality.
The 4-window configuration allows simultaneous excitation and emission, making it a reliable tool for a wide range of fluorescence and biochemical applications.

Key Features

Sample volume: 1.75 mL (1750 µL) — suitable for medium to large sample volume fluorescence measurements.
5 mm internal width: offers higher signal intensity and enhanced optical performance.
10 mm optical path length: standard geometry, compatible with most spectrofluorometers and spectrophotometers.
4 optical windows: enables efficient excitation and emission detection.
Fused fabrication: high thermal stability (up to 600 °C) and resistance 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
Environmental and trace analysis

About Fused Fabrication

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

Excellent heat resistance — up to 600 °C.
High optical clarity and dimensional precision for accurate 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 fluorescence measurements requiring medium to large sample volumes.
Best used with aqueous or moderate solvents.
Not suitable for long-term storage of aggressive organic solvents.

Note: Fused quartz cuvettes provide superior optical clarity, thermal stability, and chemical durability, making them a top choice for high-sensitivity fluorescence spectroscopy.

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.
