Quartz triangular cuvette, 1.75 ml, Standard 80 (>80%). Three-Way Light for 90° fluorescence detection. 190–2500 nm. PTFE Stopper. 1 pc/ea. SKU: C153SS1. In Stock.
Description
The C153SS1 is a stoppered quartz triangular cuvette with three-way light transmission, designed for fluorescence spectroscopy involving volatile or hazardous samples that require a sealed optical chamber. The PTFE stopper prevents evaporation and contamination, while Standard 80 fabrication (>80% transmittance, 190–2500 nm) ensures consistent UV–Vis–NIR performance across the full 1.75 ml working volume.

Why Triangular Geometry?
Triangular cuvettes feature three optically polished faces arranged in a prism configuration. This geometry enables simultaneous excitation and 90° emission collection — the standard measurement angle in fluorescence spectroscopy — while the third face can serve as a reference or secondary detection path. Compared to standard rectangular four-window cells, triangular cuvettes minimize back-reflection artifacts and reduce inner-filter effects.

Why Standard 80?
Standard 80 cuvettes use precision adhesive bonding to achieve transmittance above 80% at a competitive price point. The bonding process delivers reliable optical performance for routine fluorescence and spectroscopic measurements, making it an economical choice for teaching labs, screening assays, and high-throughput workflows.
Usage Tips
Cleaning: Rinse with spectroscopic-grade solvent immediately after use. For stubborn residue, soak in chromic acid or dilute HNO₃, then rinse thoroughly with deionized water.
Handling: Hold by the frosted or non-optical face only. Fingerprints on polished surfaces cause scattering artifacts in fluorescence measurements.
Orientation: Align the excitation beam perpendicular to one polished face; position the emission detector at 90° through the adjacent polished face for optimal signal-to-noise ratio.
