Description

The C151CS is a quartz fluorescent powder sample cell and four-way light optical configuration — all four vertical faces are polished to optical grade, enabling both standard UV-Vis absorbance and 90° fluorescence detection. With a 700ul internal volume, the cell is compatible with most commercial spectrophotometers. Fabricated using Molded 83 (>83% transmittance) — precision-molded from a single piece of quartz, eliminating adhesive joints entirely. Features a completely unique cylindrical ring design (17mm OD, 15mm ID, 5mm height) resembling a short quartz tube or petri-dish shape, purpose-built for powder fluorescence measurements with a flat quartz cover. This is unlike any traditional cuvette form factor.

Spectroscopy Applications

◆ UV-Vis Absorbance Spectroscopy — quantitative concentration, kinetics, Beer–Lambert studies

◆ Fluorescence Spectroscopy — 90° excitation/emission for fluorescent probes, dyes, and quantum dots

◆ DNA / RNA Quantification — nucleic-acid purity checks at 260/280 nm

◆ Protein Assays — Bradford, BCA, Lowry, and direct A280 measurements

◆ Enzyme Kinetics — real-time substrate conversion and inhibition studies

◆ Water Quality & Environmental — COD, nitrate, phosphate, heavy-metal colorimetric tests

◆ Pharmaceutical QC — dissolution testing, drug concentration, stability monitoring

◆ Chemical Reaction Monitoring — reaction progress tracking via absorbance changes

Why Four-Way Light?

Four-way light cuvettes have all four vertical faces polished to optical grade, enabling both standard absorbance measurements and 90° fluorescence detection geometry. The excitation beam enters through one face while emission is collected at right angles through an adjacent face — the standard configuration required by fluorimeters and spectrofluorometers.

Why Open Top?

This cuvette features an open-top design without a cap or cover, providing unrestricted access to the sample chamber for easy filling, mixing, and cleaning. The open design is ideal for workflows requiring frequent sample changes, titration experiments, or when using dip probes and fiber-optic accessories that need direct access to the liquid surface.

Why Molded 83?

Molded 83 uses monolithic fused-quartz construction — no adhesive joints — delivering >83% UV transmittance from 200–2500 nm. Because there are no glue seams, the cell withstands all common laboratory solvents, concentrated acids, and bases (avoid HF). This fabrication is ideal for demanding analytical workflows where chemical resistance, long service life, and maximum optical clarity are priorities.

Usage Tips

Rinse with a compatible solvent (e.g., ethanol or the measurement solvent) before first use to remove any residual particles.
Do not use abrasive materials or brushes on the polished optical faces — wipe gently with lens tissue.
Withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid).
Store in the original protective case to prevent scratches on the optical windows.
For baseline correction, fill with your reference solvent, and run a blank before sample measurements.
