Description

The C104CE21 is a precision quartz micro fluorescence cuvette with 10 mm path length and four-way light optical windows (all four faces optically polished), designed for fluorescence and UV-Vis spectroscopy (190–2500 nm). The four-way configuration enables simultaneous excitation and emission measurements at 90° — the standard geometry for fluorescence spectroscopy — while maintaining full UV-Vis absorbance capability through any pair of opposing faces. The reduced 5 mm interior width creates a 1.75 ml working volume — half that of a standard 3.5 ml cell — conserving precious samples while maintaining the full 10 mm optical path for Beer–Lambert law compliance. Fabricated using Molded 83 — a 1200 °C fusion process with ±0.02 mm dimensional tolerance — achieving >83% transmittance with the highest optical quality. Includes a PTFE cap for chemical-resistant sealing.

Applications

◆ Fluorescence spectroscopy & emission scanning

◆ Fluorescence quantum yield measurement

◆ Protein & nucleic acid fluorescence assays

◆ Drug discovery & fluorescent compound screening

◆ Precious sample conservation (1.75 ml vs 3.5 ml standard)

Why This Cuvette?

The four-way (all-clear) optical windows enable simultaneous 90° excitation and emission measurements — the standard geometry for fluorescence spectroscopy. All four faces are optically polished to the same high standard, so you can rotate the cuvette and use any pair of opposing faces as the measurement path. The micro volume design (1.75 ml vs 3.5 ml) conserves precious samples while maintaining the full 10 mm optical path. The Molded 83 fabrication (±0.02 mm tolerance, 1200 °C fusion) ensures the highest dimensional precision and optical consistency for quantitative fluorescence and absorbance work.

Why Micro Volume?

Internal quartz masking walls narrow the measurement chamber to 5 mm while maintaining the full 10 mm optical path (Beer–Lambert law: A = εlc). This saves 50% of sample compared to a standard 3.5 ml cuvette, making it ideal for precious biological samples, expensive reagents, or limited column fractions. Unlike ultra-micro cuvettes with raised platforms, the micro volume design keeps the sample at full column height — compatible with all spectrophotometer beam heights (8.5 mm, 15 mm, or 20 mm) without verification.

Usage Tips: Handle by the top rim only — all four optical faces must remain free of fingerprints. Fill to at least 15 mm above the beam center height. Clean with spectroscopic-grade solvent and lint-free tissue after each use. Molded 83 construction is compatible with most laboratory solvents including water, ethanol, DMSO, and dilute acids/bases. Avoid HF (hydrofluoric acid). Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Horiba, Edinburgh Instruments, and most commercial fluorimeters and UV-Vis spectrophotometers.
