Description

VAOF5 – 1.75 mL Standard Absorption Cuvette (Fused, 5 mm Lightpath, 2 Windows)

The VAOF5 is a standard fused quartz absorption cuvette with a 5 mm optical path length and a 1.75 mL sample volume.
Manufactured using Fused Fabrication (assembled with quartz powder), it provides excellent UV/VIS transmission, heat resistance, and broad chemical compatibility, making it a cost-effective choice for daily analytical use.

Key Features

5 mm optical path length: ideal for medium to high concentration samples and routine absorption spectroscopy.
Fused fabrication: good optical transmission and reliable performance for general laboratory use.
2 optical windows: optimized for standard absorbance measurements.
Round base design: fits standard cuvette holders easily.
Wavelength range: 190–2500 nm (UV/VIS).
Thermal resistance: up to 600 °C (1112 °F).
Chemical compatibility: resistant to most acids and bases; not suitable for HF, toluene, acetone, or aggressive organic solvents.
Pathlength tolerance: ±0.06 – 0.08 mm.
Secure packaging: foam and bubble wrap; drop-tested from 1 meter before shipment.

Typical Applications

UV/VIS absorption spectroscopy
Medium to high concentration solution analysis
Environmental, chemical, and pharmaceutical testing

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.
