Description

VAOB50 – 50 μL Sub-Micro Quartz Cuvette (Bonded, All Black, 2 Windows)

The VAOB50 is a sub-micro quartz cuvette designed for absorption spectroscopy with extremely small sample volumes. With an all-black wall design to minimize stray light and a 2 × 2.5 mm aperture, this cuvette delivers stable and precise results for trace-level aqueous measurements.

Key Features

Ultra-low sample volume: only 50 μL, ideal for precious or limited aqueous samples.
All black walls: effectively minimize stray light and improve S/N ratio.
Bonded fabrication: fast customization, lower cost, and suitable for standard aqueous sample measurements.
2-window design: optimized for absorbance and transmission measurements.
10 mm optical path length: standard for most UV/VIS spectrophotometers.
PTFE lid: helps minimize evaporation and contamination during sensitive testing.
Wavelength range: UV/VIS (190 – 2500 nm).

Typical Applications

Absorbance and transmission of aqueous solutions
Trace analysis with limited sample volume
Life science and biochemical assays
Water-based pharmaceutical or environmental testing

About Bonded Fabrication

Bonded quartz cuvettes are produced by precision optical bonding, which makes them:

Best suited for aqueous samples only (not compatible with aggressive organic solvents).
Fast and flexible to customize, with lower production cost.
Good optical clarity and stable path length tolerance of ±0.06 – 0.08 mm.

Note: For experiments involving aggressive organic solvents or long-term chemical exposure, molded cuvettes are recommended for superior durability and chemical resistance.

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.
