Description

VAPBH2 – 0.7 mL Semi-Micro Quartz Cuvette (Bonded, 2 mm Width, 2 Windows, Black Walls, PTFE Stopper)

The VAPBH2 is a bonded quartz cuvette designed for UV/VIS absorption spectroscopy, particularly when working with limited sample volumes and concentrated solutions.
With a 2 mm internal width and standard 10 mm light path, it combines high optical accuracy with efficient sample usage.
The black walls effectively block stray light and reduce background noise, enabling more precise and stable readings.

Key Features

Sample volume: 0.7 mL — suitable for semi-micro sample handling.
10 mm light path: industry-standard path length for most spectrophotometers.
2 mm internal width: provides stable signal performance with moderate sample volume.
Black walls: minimize reflection and stray light, improving measurement accuracy.
Bonded fabrication: fast customization and cost-effective production with ±0.06–0.08 mm path length tolerance.
Wavelength range: UV/VIS (190 – 2500 nm).

Typical Applications

UV/VIS absorption measurements of moderate volume samples
Protein and enzyme concentration studies
Pharmaceutical and chemical testing
Light-sensitive sample analysis

About Bonded Fabrication

Bonded quartz cuvettes are assembled from precision-polished quartz components, offering:

Faster customization and more economical pricing than molded or fused types.
Path length tolerance of approximately ±0.06–0.08 mm.
Best used with aqueous samples.

Usage Notes

Ideal for routine lab analysis with moderate volumes.
Not suitable for prolonged exposure to strong organic solvents.
Black walls reduce background noise and enhance signal stability.

Note: Bonded cuvettes provide an excellent balance of precision and affordability for standard spectroscopy applications. For enhanced chemical resistance or extended solvent use, molded cuvettes are recommended.

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.
