Description

VCPFTR Triangular Quartz Cuvette with Stopper is a precision fused quartz cuvette designed for high-sensitivity fluorescence and UV/Vis applications. Its triangular body (45 × 18 × 13 mm) and 90° geometry effectively minimize stray light and internal reflections, delivering enhanced signal-to-noise ratios in fluorescence measurements.

With a 10 mm optical path length and a 1.75 mL chamber volume, this cuvette is well suited for standard fluorometers, right-angle detection configurations, and low-to-medium volume samples. The included PTFE stopper helps seal the chamber to reduce evaporation and contamination, ensuring consistent measurement conditions.

Key Advantages

  • ✔ Triangular cross-section — reduces reflection and scattering, improving fluorescence detection sensitivity.
  • ✔ Four optical windows — allows flexible detection geometry, including right-angle signal collection.
  • ✔ Fused fabrication — excellent thermal stability, good chemical resistance, and stable optical performance.
  • ✔ Secure sealing — supplied with PTFE stopper for contamination and evaporation control.
  • ✔ Compact volume — ideal for fluorescence, absorbance, and kinetic assays with limited samples.

Typical Applications

  • Fluorescence spectroscopy with 90° detection
  • UV/Vis absorbance measurements
  • Protein and nucleic acid quantification
  • Dye studies, photoluminescence, and kinetic monitoring

Fused Fabrication Characteristics

  • Can be heated up to 600 °C (1112 °F).
  • Assembled with quartz powder; small gaps may absorb dyes or stains — not recommended for long-term sample storage.
  • Not suitable for HF, toluene, acetone, or aggressive organic solvents (these will shorten the service life significantly).
  • Excellent optical transmission across the UV/VIS range with reliable durability.

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.
