Description

The C502CS3 is a quartz flow cuvette with 50 mm path length and two-way light windows (two polished optical faces for standard UV-Vis absorbance geometry), holding 18 ml of sample. The cell measures 12.5 × 52.5 × 45 mm externally with an internal chamber of 10 × 50 × 43 mm. Inlet and outlet ports enable continuous sample flow for real-time monitoring applications. Fabricated using Molded 83 technique with monolithic fused-quartz construction — no adhesive joints, delivering >83% transmittance across the 190-2500 nm range. The quartz body is withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid).

Why Two-Way Light Windows?

The two-way configuration provides two optically polished opposing faces for standard transmission-mode spectroscopy (UV-Vis, NIR). The remaining two walls are frosted (ground) to suppress internal reflections and stray light, improving baseline stability and measurement reproducibility. This is the most common geometry for absorbance-based flow analysis — compatible with virtually every single-beam and double-beam spectrophotometer on the market.

Why a Flow Cell?

Flow cells enable continuous, real-time spectroscopic monitoring without manual sample handling. By connecting a flow cell to a pump or gravity-feed system, you can monitor concentration changes, reaction kinetics, or process streams in real time without removing the cell from the instrument. This eliminates human error, reduces sample exposure to air, and enables automated data collection over extended periods.

Why Molded 83 Fabrication?

The Molded 83 fabrication uses precision UV-cured adhesive to bond high-purity quartz panels. This method delivers >83% transmittance across the UV-Vis-NIR spectrum while keeping costs accessible. The adhesive joints are optically transparent and spectrally neutral, making Molded 83 cells an excellent choice for routine measurements in aqueous media where aggressive solvents are not required.

Usage Tips: Orient the cell with the polished optical faces toward the light source and detector. Fill to at least 5 mm above the beam height to avoid meniscus effects. The 50 mm path length follows Beer-Lambert law (A = εlc) — for concentrated samples, consider a shorter path. Clean with spectroscopic-grade solvent and rinse with deionized water. Avoid scratching the optical faces; handle by the frosted walls or edges. Compatible with standard spectrophotometer cuvette holders (12.5 mm external width models).

Disclaimer: Specifications are nominal values measured under standard laboratory conditions. Actual transmittance may vary slightly with wavelength and sample composition. Images are representative; minor cosmetic variations between production batches are normal and do not affect optical performance. For critical applications, request a Certificate of Analysis at time of order.
