Description

VFOF03 Dual Pathlength Fused Quartz Cuvette is a 4-window wide clear wall cuvette designed for fluorescence and UV/VIS spectroscopy. It features a dual optical path length of 3 mm and 20 mm, providing excellent flexibility for both low-concentration and higher signal measurements. With a 2.1 ml capacity, it is ideal for small to medium sample volumes, making it a popular choice for research and analytical applications.

Key Features

Dual pathlength (3 mm / 20 mm) — supports both short and long path measurements, enabling wider dynamic range and sensitivity control.
4-window design — allows flexible front and side detection, suitable for fluorescence spectroscopy and absorbance measurements.
2.1 ml sample volume — efficient use of precious or limited samples.
Fused quartz construction — offers excellent thermal and chemical stability, resistant up to 600 °C.
Wide spectral transmission from 190–2500 nm, ideal for UV, visible, and NIR applications.

Typical Applications

Fluorescence spectroscopy with adjustable sensitivity (short or long pathlength).
UV/VIS absorbance analysis of dilute or concentrated solutions.
Environmental monitoring, water testing, and chemical analysis.
Biochemical and photochemical studies requiring small volumes.

Fused Fabrication Notes

Constructed with fused quartz powder assembly, enabling excellent temperature tolerance (up to 600 °C).
Gaps may discolor over time; long-term storage of samples in the cuvette is not recommended.
Not suitable for HF, toluene, acetone, or other aggressive organic solvents, which can shorten service life.
Provides high transmission and dimensional precision for consistent performance.

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.
