Quartz 10 mm four-way light fluorescence cuvette, 1.1 ml, Standard 80 (>80% transmittance). PTFE Stopper. 190–2500 nm. SKU: C104SS26.
Description
The C104SS26 is a premium quartz fluorescence cuvette with 10 mm path length and four-way light optical configuration — all four vertical faces are polished to optical grade, providing the standard 90° fluorescence geometry plus additional optical access. With a micro 1.1 ml internal volume (10 × 10 × 43 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 stopper for gas-tight sealing, suitable for volatile solvents and air-sensitive samples.

Fluorescence Applications
◆ Steady-state & time-resolved fluorescence
◆ Fluorescence polarization & anisotropy
◆ Standard 90° fluorescence spectroscopy
◆ Fluorescence quenching & titration
◆ Förster resonance energy transfer (FRET)
◆ Quantum yield determination
◆ UV-Vis absorbance (190–2500 nm)
◆ Volatile solvent & air-sensitive sample measurements
Why Four-Way Light?
The four-way configuration polishes all four vertical faces plus the bottom to optical grade, providing maximum geometric flexibility for excitation and emission collection. This enables front-face fluorescence on opaque or highly concentrated samples, polarization anisotropy measurements requiring precise alignment, and bottom-read configurations used in plate-reader-adapted instruments. If your experiment only requires standard 90° fluorescence geometry, a four-way cuvette is sufficient; choose four-way when you need bottom optical access or plan to rotate the cuvette for multi-angle studies.
PTFE Stopper Closure
The precision-ground PTFE stopper provides a gas-tight seal, preventing solvent evaporation and protecting air-sensitive samples during extended fluorescence measurements. PTFE is chemically inert and contributes no background fluorescence, ensuring clean emission spectra. The stopper can be quickly removed for sample addition or replacement between measurements.
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.
