Description

The C104SQE is a quartz (fused silica) standard cuvette with 10 mm path length and four-way light optical windows (all four sides optically polished), designed for fluorescence and UV-Vis and NIR spectrophotometry across 190–2500 nm. The four-way configuration allows simultaneous excitation and emission measurements at 90° — the standard geometry for fluorescence spectroscopy. Fabricated using Molded 83 — an integrally fused one-piece construction with no adhesive or joints — this cuvette achieves >83% transmittance and a path length tolerance of ±0.02 mm. Molded 83 fabrication withstands temperatures up to 1200 °C and resists all common laboratory solvents, acids, and bases. Includes a stopper for chemical-resistant sealing. Supplied as a pack of two for cost-effective parallel or comparative experiments.

Applications

◆ Fluorescence spectroscopy with 90° excitation/emission geometry

◆ UV-Vis absorbance spectrophotometry (through any face pair)

◆ Phosphorescence and luminescence lifetime measurements

◆ Circular dichroism (CD) spectroscopy

◆ Multi-angle dynamic light scattering (DLS)

◆ Teaching and advanced research laboratories

Why This Cuvette?

The four-way (all-clear) optical windows enable simultaneous 90° excitation and emission — essential for fluorescence spectroscopy. All four faces are polished to the same standard, so you can rotate the cuvette and use any pair of opposing faces. The standard 10 mm path provides direct Beer-Lambert law compliance (A = εlc), making concentration calculations straightforward.

Usage Tips: Handle by the top rim only — all four faces are optical windows. Fill to at least 15 mm above beam height. Orient excitation through one face with detector at 90°. Use matching cuvettes for blank reference. Clean with spectroscopic-grade solvent and lint-free tissue. Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Horiba, and most fluorescence/UV-Vis spectrophotometers.
