Description

VALB200 Black-Walled Micro Flow Cuvette is a precision-engineered bonded quartz flow cell designed for high-sensitivity absorbance measurements. With a 10 mm optical path length and only 200 μL internal volume, it combines low sample consumption with strong optical performance. The black-walled construction effectively suppresses stray light and reflection, making it ideal for trace analysis and kinetic assays. The cell uses screw connectors for secure, leak-resistant fluid handling.

Key Features

  • 10 mm optical path ensures reliable absorbance readings with excellent linearity.
  • Black-walled design reduces stray light and enhances signal-to-noise ratio.
  • Micro-volume chamber (200 μL) allows for efficient use of valuable or limited samples.
  • Screw connectors provide stable, leak-free flow connections for precise liquid control.
  • Optimized for UV/VIS measurements in the 190 – 2500 nm wavelength range.

Typical Applications

  • Trace absorbance measurements with minimal sample volume.
  • Continuous flow and kinetic studies.
  • Integration with automated sampling, peristaltic pumps, or HPLC systems.
  • UV/VIS absorbance assays in environmental, biochemical, and analytical research.

Bonded Fabrication Notes

  • Bonded quartz construction provides strong sealing and precise alignment.
  • Recommended for aqueous solutions; avoid strong organic solvents or acids that can degrade the bonding layer.
  • Rinse and clean after each use to maintain optical quality and extend service life.

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.
