Description

VFOBS1 – 0.35 mL Semi-Micro Quartz Cuvette (Bonded, 1 mm Width, 4 Windows, PTFE Lid)

The VFOBS1 is a precision bonded quartz cuvette with four optical windows, specially designed for fluorescence spectroscopy and absorption measurements.
With a 1 mm internal width and a 10 mm optical path length, it enables high-sensitivity detection with minimal sample volume. The four-window design allows both excitation and emission detection, making it ideal for fluorescence experiments.

Key Features

Sample volume: 0.35 mL (350 µL) — ideal for micro-volume analysis.
1 mm internal width: perfect for high-concentration samples or minimizing sample usage.
10 mm optical path length: standard geometry compatible with most spectrophotometers and fluorometers.
4 optical windows: suitable for fluorescence excitation and emission measurements.
Bonded fabrication: ±0.06–0.08 mm path length tolerance for high precision.
Wavelength range: UV/VIS (190–2500 nm).

Typical Applications

Fluorescence spectroscopy
UV/VIS absorbance measurements
Protein and nucleic acid quantification
Clinical, biochemical, and environmental assays

About Bonded Fabrication

Bonded quartz cuvettes are assembled with precision-ground quartz plates, offering excellent optical performance.
Path length tolerance: ±0.06–0.08 mm.
Compatible with aqueous solutions and mild solvents (avoid HF, toluene, acetone, and other strong organic solvents).

About Four-Window Design

Allows both excitation and emission detection for fluorescence measurements.
Improves flexibility for right-angle or front-face fluorescence configurations.
Also compatible with standard absorbance readings.

Usage Notes

Ideal for micro-volume fluorescence and absorbance experiments.
Recommended for applications requiring high precision and sensitivity.
Handle carefully to avoid contamination or damage to optical windows.

Note: Four-window bonded quartz cuvettes provide high optical quality and versatility, making them suitable for advanced fluorescence and UV/VIS spectroscopy applications.

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.
