Description

The C305CR is a quartz quartz fluorescence cuvette with 30/5mm path length and five-way light optical configuration — four vertical faces and the bottom face are polished to optical grade, enabling standard absorbance, 90° fluorescence, and downward/upward detection geometries. With a 6ml internal volume (30 × 5 × 50 mm chamber), the cell is compatible with most commercial spectrophotometers. Fabricated using Sintered 83 (>83% transmittance) — high-temperature sintered to fuse quartz panels without adhesive. Features a rectangular 30mm x 5mm asymmetric five-way cuvette with 6ml capacity, providing different optical path lengths on perpendicular axes.

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 Five-Way Light?

Five-way light cuvettes have four vertical faces and the bottom face polished to optical grade. In addition to standard transmission and 90° fluorescence measurements, the polished bottom enables downward excitation or upward emission collection — a geometry used in total-internal-reflection fluorescence (TIRF) and certain plate-reader-style instruments.

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 Sintered 83?

Sintered 83 uses high-temperature sintering to fuse quartz panels without adhesive, delivering >83% UV transmittance from 200–2500 nm. The sintered joints are chemically inert and compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone). This fabrication is ideal for analytical workflows involving harsh chemical matrices where standard glued cells would degrade.

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.
Compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone).
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.
