Description

VFSF2 – 3.5 mL Standard Fluorescence Cuvette with Screw Cap (Fused, 10 mm Lightpath, 4 Windows)

The VFSF2 is a fused quartz fluorescence cuvette with a 10 mm optical path length and 3.5 mL sample volume. It features a screw cap and septa, offering basic sealing capability for routine fluorescence and absorption experiments, including anaerobic and oxygen-sensitive measurements under moderate conditions.

Fused fabrication offers good chemical resistance and temperature stability, making it suitable for most acidic, basic, and many organic chemical environments. However, for strong organic solvents and aggressive chemical conditions, molded fabrication provides a longer service life.

Key Features

10 mm optical path length: standard size, compatible with most fluorescence and UV/VIS spectrophotometers.
4 optical windows: enables 90° fluorescence detection with high transmission in the UV/VIS range.
Screw cap with septa: helps reduce evaporation and contamination for sensitive samples.
Fused fabrication: good temperature resistance (up to 600 °C / 1112 °F), lightpath tolerance ±0.06–0.08 mm.
Wavelength range: 190–2500 nm (UV/VIS).
Chemical compatibility: resistant to most acids, bases, and many organic solvents. For strong organics (e.g., toluene, acetone, chloroform), short-term use is possible but may shorten cuvette lifespan.
Packaging: packed with foam and bubble wrap; 1-meter drop test passed before shipment.

Typical Applications

Fluorescence spectroscopy
Routine lab analysis
Anaerobic and oxygen-sensitive measurements
Water, buffer, acid/base, and moderate solvent systems

About Fused Fabrication

Fused fabrication cuvettes provide excellent UV transparency and good chemical resistance.
Compatible with most corrosive acids, bases, and many organic solvents.
Short-term use with strong organic solvents (e.g., toluene, acetone, chloroform, dichloromethane) is possible, but repeated exposure may lead to discoloration, seal aging, or leakage.
Hydrofluoric acid (HF) must not be used — it will etch and damage quartz.
For long-term aggressive solvent exposure, molded fabrication cuvettes are recommended.

Note: VFSF2 is designed for standard fluorescence measurements with aqueous, acidic/basic, or moderately organic systems. If your experiment involves long-term or repeated exposure to strong solvents, molded fabrication is a more durable option.

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.
