Description

VFOF5020 Dual-Pathlength Quartz Cuvette is a high-capacity fused quartz cuvette designed for advanced fluorescence and UV/Vis spectroscopy. It features two optical path lengths (20 mm / 50 mm) in one cell, allowing researchers to flexibly switch between high-sensitivity and standard measurements. With a large sample volume of 53 ml and four precision-polished optical windows, it delivers excellent optical performance for analytical and research applications.

Key Advantages

Dual path length (20 mm and 50 mm) — ideal for both concentrated and trace-level measurements.
Large 53 ml chamber supports long-path, high-sensitivity experiments.
Four clear optical windows for maximum flexibility in optical detection setups.
Fused fabrication allows heating up to 600 °C (1112 °F), ensuring high stability and UV transparency.
Wavelength range: 190 – 2500 nm (UV/VIS).

Typical Applications

Fluorescence and absorbance spectroscopy for trace detection
UV/Vis analysis requiring long path length
Environmental, biochemical, and pharmaceutical research
High-temperature and high-stability optical measurements

Fused Fabrication Notes

Fused quartz can be heated up to 600 °C (1112 °F).
Assembled with quartz powder — seams may discolor over time if samples are stored too long. Long-term storage is not recommended.
Excellent resistance to most acids and solvents, but avoid HF, toluene, acetone, and other strong organic solvents, which will shorten the service life.

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.
