Description

VFOF05 Dual Pathlength Fused Quartz Cuvette is a 4-window wide clear wall cuvette optimized for both fluorescence and UV/VIS spectroscopy. It features a dual optical path length of 5 mm and 20 mm, allowing flexible detection sensitivity for a wide range of applications. With a 3.5 ml volume, it offers an excellent balance between sample efficiency and measurement precision.

Key Features

Dual pathlength (5 mm / 20 mm) — supports short and long path measurements for flexible sensitivity adjustment.
4-window configuration — allows both front and side detection, ideal for fluorescence and absorbance applications.
3.5 ml capacity — suitable for medium-volume samples, minimizing waste of precious solutions.
Fused quartz fabrication — provides excellent thermal stability (up to 600 °C) and optical clarity.
Wide transmission range of 190–2500 nm, covering UV, visible, and NIR spectroscopic applications.

Typical Applications

Fluorescence and absorbance spectroscopy with adjustable sensitivity through dual pathlength design.
Environmental and water quality analysis requiring precise optical response.
Biochemical and photochemical experiments with medium-volume samples.
Instrument calibration and trace-level analysis in research labs.

Fused Fabrication Notes

Made from fused quartz powder with minimal bonding, offering superior heat resistance and durability.
Gaps may discolor over time; not recommended for long-term sample storage.
Not suitable for HF, toluene, acetone, or other strong organic solvents, which can reduce service life.
High transmission and dimensional accuracy ensure stable and reliable measurement results.

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.
