Description

VFOF25 Fused Quartz Large Fluorescence Cuvette is a 50 ml capacity customized 4-window cuvette with dual optical path lengths of 20 mm or 50 mm. The large internal dimensions and wide clear walls are specifically designed for advanced fluorescence and absorbance experiments that require both high sensitivity and flexible optical setups.

This model is ideal for laboratories conducting precision spectroscopy on large-volume samples, as well as for specialized research and industrial applications.

Key Features

Dual optical path lengths (20 mm & 50 mm) — offers flexibility for different sensitivity and signal requirements.
50 ml capacity — suitable for large sample volumes and high signal stability.
4-window design — allows side detection and excitation, ideal for fluorescence spectroscopy.
Fused quartz construction — ensures excellent UV transparency, thermal stability, and resistance to most laboratory solvents.
Broad wavelength range: 190–2500 nm — compatible with UV/VIS/NIR instruments.

Typical Applications

High-sensitivity fluorescence spectroscopy
Absorbance and transmission studies with large sample volumes
Advanced photoluminescence and side-excitation detection
Environmental, biochemical, and industrial analysis
Custom OEM and specialized research systems

Fused Fabrication Notes

Fused quartz provides high optical transmission and dimensional stability up to 600 °C.
Not suitable for HF or aggressive organic solvents such as toluene or acetone.
Powder seams may discolor over time but do not affect measurement accuracy.
Dimensional tolerance: ±0.06–0.08 mm.

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.
