Description

VFOBS3 – 1.05 mL Semi-Micro Quartz Cuvette (Bonded, 3 mm Width, 4 Windows, PTFE Lid)

The VFOBS3 is a bonded quartz cuvette engineered for fluorescence spectroscopy, offering high optical clarity and stable performance.
With a 3 mm internal width and 10 mm optical path length, this semi-micro cuvette supports sensitive detection using both excitation and emission measurements through its 4 clear windows.
It’s ideal for fluorescence experiments where accuracy, repeatability, and low sample consumption are essential.

Key Features

Sample volume: 1.05 mL — ideal for semi-micro applications with reliable signal stability.
10 mm optical path length: compatible with most standard spectrophotometers and fluorometers.
3 mm internal width: excellent balance between sensitivity and sample economy.
4 optical windows: optimized for both excitation and emission detection.
Bonded fabrication: cost-effective and fast production with path length tolerance of ±0.06–0.08 mm.
Wavelength range: UV/VIS (190 – 2500 nm).

Typical Applications

Fluorescence spectroscopy with side detection
Enzyme and protein fluorescence assays
Biological and chemical analysis requiring low sample volumes
Fluorescent dye and kinetic measurements

About Bonded Fabrication

Bonded quartz cuvettes are assembled from precision-polished quartz plates. This fabrication method:

Provides fast lead times and cost-effective production.
Maintains precise optical performance with ±0.06–0.08 mm path length tolerance.
Best suited for aqueous solutions and routine lab use.

Usage Notes

Ideal for fluorescence experiments requiring dual detection paths.
Not recommended for long-term use with strong organic solvents.
Compact semi-micro design optimizes sample usage and measurement sensitivity.

Note: Bonded cuvettes provide excellent performance and value for routine fluorescence assays. For enhanced solvent resistance, molded or fused types are recommended.

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.
