Description

VFOB08 – 3.0 mL Custom Quartz Cuvette (Bonded, 20/30 mm Lightpath, 5 Windows)

The VFOB08 is a high-precision custom bonded quartz cuvette designed for advanced fluorescence spectroscopy and UV/VIS applications. With a unique dual lightpath of 20 mm and 30 mm, it provides exceptional flexibility for both standard and high-sensitivity measurements.
This cuvette has a 3.0 mL sample volume and five optical windows, making it ideal for specialized experiments that require multiple excitation or detection angles.

Key Features

Sample volume: 3.0 mL — suitable for large-sample fluorescence and absorbance experiments.
Dual optical path length: 20 mm / 30 mm — allows both standard and high-sensitivity measurement setups.
Five-window design: enables multiple excitation/detection angles, perfect for advanced optical configurations.
Bonded fabrication: provides precise path length tolerance of ±0.06–0.08 mm.
Wavelength range: UV/VIS (190–2500 nm).
Outer dimensions: 33 × 8 × 23 mm — compact and robust structure for custom instrumentation.

Typical Applications

Fluorescence spectroscopy with multiple excitation angles
UV/VIS absorbance and transmission studies
High-sensitivity or long-path experiments
Photoluminescence, light scattering, and environmental analysis

About Bonded Fabrication

Bonded quartz construction ensures optical stability and alignment.
Path length tolerance: ±0.06–0.08 mm.
Excellent chemical resistance to most aqueous solutions and mild solvents (not suitable for HF or aggressive organic solvents such as toluene or acetone).

About 5-Window Design

Enables flexible optical setups with multiple detection or excitation ports.
Ideal for fluorescence spectroscopy, photoluminescence, or light scattering.
Supports both short and long pathlength measurements in a single cell.

Usage Notes

Compatible with advanced fluorescence and UV/VIS spectrometers.
Best suited for applications where optical flexibility and high sensitivity are required.
Handle carefully to protect optical windows from scratches or contamination.

Note: The VFOB08 cuvette combines long path length with a multi-window design, making it a powerful tool for advanced optical research and precision spectroscopy.

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.
