Description

The C033CS is a premium quartz fluorescence cuvette with 3 mm path length and three-way light optical configuration — three vertical faces are polished to optical grade, supporting 90° fluorescence geometry with reduced scattered light from the non-polished face. With a micro 45 µl internal volume (3 × 3 × 44 mm chamber), the cell is compatible with most commercial fluorimeters and UV-Vis spectrophotometers. Fabricated using Standard 80 (>80% transmittance) — assembled with optical-grade adhesive for reliable performance with aqueous samples. Includes a PTFE cap for dust protection and evaporation control.

Why Three-Way Light?

The three-way configuration polishes three vertical faces to optical grade while leaving the fourth face frosted or unpolished. This reduces scattered excitation light reaching the detector in 90° geometry, improving signal-to-noise ratio for weakly fluorescent samples. The unpolished rear face acts as a light trap, minimizing back-reflections that can contribute to background fluorescence.

PTFE Cap

The PTFE cap provides dust protection and reduces solvent evaporation during measurements. PTFE is chemically inert and contributes no background fluorescence, ensuring clean emission spectra. The cap fits securely over the cuvette opening and can be quickly removed for sample addition.

Why Standard 80 Construction?

Standard 80 cuvettes are assembled using optical-grade adhesive to bond precision quartz panels, achieving transmittance >80% at 200–2500 nm. This fabrication method delivers reliable optical performance at an accessible price point — ideal for routine fluorescence measurements with aqueous samples. Standard 80 cuvettes are intended for use with aqueous (water-based) solutions only; organic solvents, strong acids, or strong bases may attack the adhesive joints. For solvent-resistant applications, consider Sintered 83 or Molded 83 alternatives.

Usage Tips: Handle by non-optical surfaces only — fingerprints on polished faces cause scattering artifacts that raise fluorescence background. Rinse immediately after use. Standard 80 construction is suitable for aqueous (water-based) solutions only. Do not use with organic solvents, strong acids, or strong bases, as these may attack the adhesive joints. For fluorescence work, ensure the excitation beam enters through a polished window and the detector views at 90° through an adjacent polished face. Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Hitachi, Horiba, Edinburgh Instruments, and most commercial fluorimeters.
