Description

The C033SS is a precision-crafted quartz triangular cuvette with three-way light transmission and a sealed PTFE stopper, ideal for fluorescence spectroscopy where excitation and emission paths must be separated at 90°. With 1.75 ml capacity and Sintered 83 fabrication (>83% transmittance across 190–2500 nm), this cuvette delivers superior optical clarity for demanding multi-angle measurement setups.

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.

Applications

◆ Fluorescence Spectroscopy (excitation/emission at 90°)
◆ Raman Spectroscopy
◆ Phosphorescence & Luminescence Analysis
◆ Fluorescence Polarization / Anisotropy
◆ Multi-Angle Light Scattering (MALS)
◆ Turbidimetry & Nephelometry
◆ Environmental Water Quality Monitoring
◆ Pharmaceutical QC & Drug Analysis

Why Sintered 83?

Sintered 83 cuvettes are fabricated using a high-temperature fusion process that produces seamless quartz joints with no adhesive residue. This yields transmittance above 83% and exceptional chemical resistance — ideal for aggressive solvents, strong acids/bases, and high-temperature applications where adhesive-bonded cells may degrade.

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.
