Quartz 10mm dual-window fluorescence cuvette, 1.5ml, Molded 83 (>83% transmittance). Five-Way Light. Open Top (No Cap). 190–2500 nm. SKU: C105CS1.
Description
The C105CS1 is a quartz dual-window fluorescence cuvette with 10mm 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 1.5ml internal volume (4.5 × 4.5 × 35 mm chamber), 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 unique dual-window configuration with a notched bottom edge (4.5mm cutout visible), creating five-way optical access. The clear 12.5mm x 12.5mm body shows both the standard measurement windows and the additional bottom optical path.

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 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.
