Description

VALB321 Black-Walled Flow Through Cuvette is a precision quartz cuvette specifically designed for micro-volume absorbance measurements requiring high stability and low background noise. With a 10 mm optical path length and a 32 μL sample volume, this cuvette is ideal for applications where light control, sensitivity, and sample economy are critical. The black-walled design minimizes stray light and reflections, providing excellent signal-to-noise performance, while the stainless steel inlet and outlet tubes ensure reliable and stable fluid flow.

Key Advantages

Black-walled construction effectively reduces stray light and background signal for more accurate detection.
Micro-volume capacity (32 μL) conserves precious samples while maintaining measurement precision.
Continuous flow configuration supports stable, repeatable inline absorbance measurements.
Excellent optical transmission over the UV/VIS range (190–2500 nm).
Stainless steel tubing provides a secure, leak-resistant connection suitable for various fluidic systems.

Fabrication Method Features – Bonded*

Path length tolerance: ±0.06–0.08 mm.
Cost-effective fabrication with clean, clear optical flow paths.
Recommended for aqueous samples only; not suitable for aggressive organic solvents.
Reliable and stable for standard laboratory and OEM applications.

Typical Applications

Micro-volume absorbance spectroscopy
Flow injection and kinetic measurements
Biological and clinical 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.
