Quartz 10mm Stoppered Fluorescence Cuvette, 3.5 ml, Molded 83, Four-Way Light, PTFE Stopper, Pack of Two, C104SE6
USD$320.00 USD$288.00
Quartz 10 mm four-way light stoppered cuvette, 3.5 ml, Molded 83 (>83% transmittance). PTFE Stopper for airtight sealing. 190–2500 nm. Pack of Two. SKU: C104SE6.
Description
The C104SE6 is a quartz stoppered 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 standard 3.5 ml internal volume (10 × 10 × 43 mm chamber), the cell is compatible with most commercial spectrophotometers and fluorimeters. Fabricated using Molded 83 (>83% transmittance) — the cuvette body is integrally fused as a single piece with no adhesive joints. The PTFE stopper seals the cuvette opening, preventing evaporation of volatile samples and protecting air-sensitive or hygroscopic solutions during measurement.

Fluorescence & Spectroscopy Applications
Why Four-Way Light?
The four-way configuration polishes all four vertical faces to optical grade — the standard geometry for fluorescence spectroscopy. The excitation beam enters through one face and emission is collected at 90° through an adjacent face, minimizing excitation light contamination in the emission signal. The additional two polished faces allow the cuvette to be rotated for alternative measurement geometries or simultaneous absorbance monitoring during fluorescence experiments.
PTFE Stopper
The PTFE stopper creates an airtight seal over the cuvette opening, preventing solvent evaporation during extended measurements and protecting air-sensitive or hygroscopic samples from atmospheric exposure. PTFE is chemically inert to virtually all laboratory solvents and contributes no background absorbance or fluorescence, ensuring clean spectra. The stopper fits snugly by friction and can be removed and replaced one-handed for rapid sample exchange. Ideal for volatile solvents, long kinetic runs, and any application where maintaining sample concentration and composition is critical.
Why Molded 83 Construction?
Molded 83 is the premium fabrication method: the cuvette is integrally fused as a single piece with no adhesive or joints. This eliminates solvent attack points and enables operation up to 1200 °C — far exceeding sintered (600 °C) or glue-assembled (200 °C) alternatives. Dimensional tolerance is ±0.02 mm. The monolithic construction withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid). Critically for fluorescence work, the absence of adhesive removes a common source of background fluorescence that can contaminate emission spectra. With transmittance >83%, Molded 83 is the gold standard for demanding research.
