Description
The C205CR3 is a quartz cuvette with cover made of quartz for fluorescence with 20mm 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 2.4ml internal volume (20 × 7.5 × 20 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 distinctive shallow box-shaped design (20mm x 20mm x 7.5mm, outer 21mm x 21mm x 8.5mm) with a removable quartz cover plate, creating a lidded fluorescence cell for powder or film samples.

◆ 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 a Quartz Cover?
The quartz cover plate provides a flat, optically transparent seal over the sample chamber. Unlike PTFE caps, a quartz cover allows top-down excitation or emission collection — enabling five-way optical access for advanced fluorescence geometries. The cover also minimizes evaporation and keeps contaminants out of the sample during measurements while maintaining full UV-Vis transparency across 190–2500 nm.
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.
