Description

VAOBS1 – 0.35 mL Semi-Micro Quartz Cuvette (Bonded, 1 mm Width, 2 Windows, PTFE Lid, Black Walls)

The VAOBS1 is a specialized bonded quartz cuvette with black walls, designed for UV/VIS absorption spectroscopy where low stray light and precise micro-volume measurement are required.
Featuring a 1 mm internal width and a 10 mm optical path length, it is ideal for small-volume, high-sensitivity applications. The black-walled design minimizes background reflections and enhances measurement accuracy, particularly useful for low-concentration samples.

Key Features

Sample volume: 0.35 mL (350 µL) — ideal for micro-volume applications.
1 mm internal width: maximizes absorbance for high-concentration samples with minimal sample volume.
10 mm optical path length: standard dimension for most spectrophotometers.
2 optical windows: designed for precise and stable absorbance measurements.
Black walls: effectively reduce stray light, improving signal-to-noise ratio and measurement sensitivity.
Bonded fabrication: ±0.06–0.08 mm path length tolerance for reliable analytical results.
Wavelength range: UV/VIS (190–2500 nm).

Typical Applications

Trace analysis and low-concentration absorbance
Protein and nucleic acid quantification
Clinical and biochemical assays
High-sensitivity UV/VIS spectroscopy

About Bonded Fabrication

Made by bonding high-quality quartz plates, providing stable and cost-effective optical performance.
Path length tolerance ±0.06–0.08 mm.
Compatible with aqueous solutions and mild solvents (avoid HF, toluene, acetone, and strong organic solvents).

About Black Walls

Effectively suppresses stray light and light scattering from the sides.
Enhances measurement precision for micro-volume and low-signal assays.
Commonly used in clinical, biological, and environmental testing applications.

Usage Notes

Designed for micro-volume UV/VIS absorbance experiments.
Ideal for high-concentration samples and low-noise detection.
Avoid long-term storage with strong solvents to extend cuvette life.

Note: Black-walled quartz cuvettes minimize stray light interference, making them ideal for trace detection and micro-volume analysis.

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.
