Description

VAOFI2 Fused Quartz IR Cuvette is a 2-window IR cuvette designed for high-precision transmission measurements. With a 2 mm optical path length and 700 µL internal volume, this cell strikes an excellent balance between path length and sample volume, making it ideal for IR absorbance experiments. The round base ensures good compatibility with various IR and UV/VIS instruments, and the PTFE lid provides basic sample protection.

Key Features

2 mm optical path — ideal for medium concentration measurements with reduced path-induced attenuation.
2-window configuration — optimized for absorbance and IR transmission studies.
Fused quartz body — wide spectral range (250 – 3500 nm), excellent IR transmittance, and high chemical resistance.
PTFE lid — offers basic sealing to reduce evaporation and contamination during short experiments.
Thermal resistance up to 600 °C — suitable for high-temperature chemical testing environments.

Typical Applications

Infrared and NIR absorbance spectroscopy (250 – 3500 nm).
Concentrated solution measurements where shorter path length improves signal.
Low- to medium-volume analytical work in chemical, pharmaceutical, and environmental testing.
High-temperature and solvent-resistant experimental setups.

Fused Fabrication Notes

Constructed from fused quartz powder for excellent heat and optical stability.
Gaps may discolor with use; not intended for long-term storage of samples.
Not compatible with HF, toluene, acetone, or other aggressive solvents.
Each cell is drop-tested at 1 m height and packed securely with foam and bubble wrap before shipment.

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.
