Description

VALB16 Black-Walled Flow Through Cuvette is a high-precision quartz cuvette engineered for ultra-low volume absorbance measurements where stability, low background noise, and precise light control are critical. With a 5 mm optical path length and a 16 μL sample volume, this cuvette is ideal for applications involving small and precious samples. Its black-walled construction effectively suppresses stray light and reflections, significantly enhancing signal-to-noise performance. The stainless steel inlet and outlet tubes ensure stable, secure, and leak-resistant continuous flow operation.

Key Advantages

Black-walled structure minimizes stray light and improves measurement sensitivity.
Ultra-low volume (16 μL) reduces sample consumption, ideal for limited or expensive samples.
Continuous flow configuration ensures stable and repeatable absorbance measurements.
Excellent optical performance in the UV/VIS range (190–2500 nm).
Stainless steel tubing offers robust and stable fluidic connections.

Fabrication Method Features – Bonded*

Path length tolerance: ±0.06–0.08 mm.
Clean, cost-efficient fabrication suitable for routine analysis.
Recommended for aqueous samples only; not suitable for organic solvents.
Stable optical performance and reliable alignment.

Typical Applications

Ultra-micro absorbance spectroscopy
Flow injection analysis
Clinical and biological assays
Inline and OEM detection systems

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.
