Description

VAOF18 Fused Quartz Fluorescence Cuvette is a 1.8 ml capacity cuvette featuring dual optical path lengths of 1 mm and 10.5 mm, specifically designed for high-sensitivity fluorescence spectroscopy and specialized analytical applications. The compact geometry (45 × 12.5 mm) and 4 clear windows make this model well suited for low-volume sample measurements and OEM system integration.

This cuvette is made from high-purity fused quartz, ensuring superior UV transmission, excellent thermal stability, and chemical resistance, making it ideal for advanced research and precise analytical measurements.

Key Features

  • Dual optical path (1 mm & 10.5 mm) — supports flexible experimental setups with one cuvette.
  • 4 clear windows — optimized for fluorescence excitation and emission at 90° detection.
  • Compact external size (45 × 12.5 mm) — ideal for micro-volume measurements and limited instrument space.
  • Fused quartz construction — provides excellent UV transparency, thermal stability up to 600 °C, and chemical resistance.
  • Broad wavelength range: 190–2500 nm — compatible with UV/VIS/NIR fluorescence systems.

Typical Applications

  • Fluorescence spectroscopy and low-volume assays
  • OEM and custom optical systems
  • Life sciences and biochemical analysis
  • Environmental and trace detection applications
  • Advanced analytical and R&D work

Fused Fabrication Notes

  • Fused quartz ensures high optical transmission and dimensional stability under elevated temperatures.
  • Not suitable for hydrofluoric acid (HF) or strong organic solvents like toluene and acetone.
  • Powder seams may discolor over time but do not impact optical accuracy.
  • Typical dimensional tolerance: ±0.06–0.08 mm.

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.
