Description

VFOB20 – 1.9 mL Custom Quartz Cuvette (Bonded, 10 mm Lightpath, 4 Windows)

The VFOB20 is a high-quality custom bonded quartz cuvette engineered for fluorescence spectroscopy and UV/VIS absorbance measurements. Featuring a 10 mm optical path length and 1.9 mL sample volume, it is ideal for standard spectroscopic experiments that require precision and stability. The four-window design provides excellent flexibility for excitation and emission measurements.

Key Features

Sample volume: 1.9 mL (1900 µL) — suitable for standard volume fluorescence assays.
10 mm optical path length: the standard for most UV/VIS spectrometers.
Four optical windows: support for multi-angle fluorescence detection or dual-beam setups.
Bonded fabrication: ensures precise path length with tolerance ±0.06–0.08 mm.
Wavelength range: UV/VIS (190–2500 nm).
Outer dimensions: 20 × 12 × 12 mm — compact and compatible with custom instruments.

Typical Applications

Fluorescence spectroscopy
UV/VIS absorbance measurements
Protein and nucleic acid quantification
Environmental and chemical analysis

About Bonded Fabrication

Bonded quartz cuvettes are constructed with precision-ground plates for high optical accuracy.
Typical path length tolerance: ±0.06–0.08 mm.
Excellent chemical resistance to most aqueous solutions and mild solvents (not recommended for HF or strong organic solvents like toluene or acetone).

About Four-Window Design

Allows simultaneous excitation and emission measurement.
Optimized for right-angle fluorescence detection and absorbance setups.
Widely used in biochemical, life science, and environmental testing.

Usage Notes

Compatible with most standard fluorescence and UV/VIS spectrometers.
Rinse and dry carefully after use to maintain optical clarity.
Handle gently to protect polished optical surfaces.

Note: Bonded quartz cuvettes provide precise optical path length and are ideal for standard fluorescence spectroscopy and absorbance measurements in laboratory research.

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.
