Description

VCLBFN Standard Quartz Cuvette with Funnel is a precision-bonded optical cell designed for laboratory and analytical applications where ease of use, sample stability, and reliable transmission measurements are required.
Its integrated funnel allows for smooth, spill-free sample loading, making it particularly suitable for experiments involving aqueous solutions and delicate samples.
With a 10 mm optical path length and 4 polished windows, it supports both absorbance and fluorescence measurements with high clarity and reproducibility.

Typical Applications

  • UV-Vis absorbance spectroscopy in research and analytical chemistry
  • Fluorescence and kinetic studies (aqueous samples only)
  • Pharmaceutical and biotechnology R&D
  • Environmental testing and water quality analysis
  • Routine laboratory workflows requiring stable optical performance

Key Features

  • 4-window bonded quartz construction for dual absorbance and fluorescence measurements
  • Integrated funnel simplifies sample handling and reduces loss
  • 10 mm optical path compatible with standard spectrophotometers
  • Excellent UV/VIS transmission and chemical resistance to aqueous media
  • Cost-effective option for routine lab measurements

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.
