Description

VAOB02 – 70 µL Ultra Micro Quartz Absorption Cuvette (Bonded, 0.2 mm Lightpath, 2 Windows)

The VAOB02 is an ultra micro-volume bonded quartz cuvette designed for high-concentration absorbance measurements with extremely short optical path lengths. It offers a 0.2 mm path length and 70 µL volume, making it highly efficient for applications where minimal sample volume is required. Its bonded structure provides reliable sealing for aqueous samples.

Key Features

0.2 mm optical path length: ideal for highly concentrated samples to avoid signal saturation.
Ultra low volume: only 70 µL required, minimizing sample waste.
Two optical windows: standard design for absorbance measurements.
Bonded fabrication: economical and practical for aqueous solutions and general laboratory use.
Wavelength range: UV/VIS (190–2500 nm).
Compatible with aqueous samples only — not for acid, base, or organic solvents.
Temperature resistance: up to 100 °C (212 °F).
Packaging: foam and bubble wrap with 1 m drop-test protection.

Typical Applications

High-concentration UV/VIS absorbance measurement
Biochemical and aqueous solution analysis
Micro-volume photometric assays
Laboratory and QA/QC 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.
