Description

VAOF39 Fused Quartz Fluorescence Cuvette is a 4-window cuvette with a 10.8 ml volume, designed for dual light path operation (5 mm and 31 mm).
Its wide and tall geometry allows flexible use in fluorescence and absorbance spectroscopy, making it an excellent option for both standard laboratory work and specialized analytical setups.

The 4-window configuration supports both front-face and right-angle detection, which is particularly important for fluorescence experiments that require excitation and emission to be measured at different angles.
This design also provides excellent compatibility with a wide range of standard spectrophotometers and fluorescence instruments.

Key Features

Dual optical path (5 mm & 31 mm) — enables flexible measurement setups for different sensitivity requirements.
4-window design — ideal for fluorescence excitation and emission detection.
Fused quartz construction — ensures outstanding optical clarity, high chemical resistance, and thermal stability.
Wavelength range: 190–2500 nm — suitable for UV/VIS and fluorescence applications.
Spacious geometry — accommodates larger sample volumes for consistent measurements.

Typical Applications

Fluorescence spectroscopy with dual-angle detection
UV/VIS absorbance and transmission measurements
Environmental and chemical analysis
Biotech and pharmaceutical R&D
Custom analytical system integration

Fused Fabrication Notes

Fused quartz provides superior optical performance, chemical durability, and heat resistance up to 600 °C.
Not suitable for hydrofluoric acid (HF) or strong organic solvents such as toluene and acetone.
Powder seams may discolor with time but do not affect measurement accuracy.
Typical 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.
