Description

VFOB200N Sub Micro Fluorescence Cuvette (4-Windows, All Black)

The VFOB200N is a sub-micro quartz fluorescence cuvette designed for high-sensitivity fluorescence and absorbance measurements using low sample volumes.
With a 10 mm optical pathlength and a 200 µL working volume, this cuvette is ideal for experiments requiring strong signal collection while minimizing sample consumption.
The 4-window design supports excitation and emission at 90°, and the all-black wall construction minimizes stray light to ensure the highest signal-to-noise ratio.

Key Features

200 µL working volume — ideal for sub-micro fluorescence and absorbance applications.
10 mm optical pathlength — standard compatible with most fluorometers and spectrophotometers.
4-window configuration — allows both excitation and emission detection at 90° for fluorescence experiments.
All-black walls — suppress background and reflections, improving fluorescence sensitivity.
Bonded fabrication — economical and customizable; suitable for aqueous and mild buffer solutions.
PTFE lid included — reduces evaporation during longer measurements or sensitive assays.

Typical Applications

Fluorescence spectroscopy with low-volume samples
Protein and nucleic acid quantification
Enzyme kinetics and biochemical assays
Environmental trace analysis

Bonded Fabrication Notes

Recommended for aqueous and mild buffer solutions.
Not suitable for HF, strong acids/bases, or aggressive organic solvents.
Advantages: low cost, fast delivery, and flexible customization.
Optical path tolerance: ±0.06 – 0.08 mm.
For harsher chemical environments, consider fused or molded quartz cuvettes.

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.
