Description

The C2.52CS1 is a quartz sample flow cell with 2.5 mm path length and two-way light windows (two polished optical faces for standard UV-Vis absorbance geometry). The cell measures 10.5 × 25 × 50 mm externally with an internal chamber of 2.5 × 17 × 50 mm. The open-top design allows easy sample loading by pouring, pipetting, or dip-sampling directly from reaction vessels. Fabricated using Standard 80 technique with precision-glued quartz construction, delivering >80% transmittance across the 190-2500 nm range. The quartz body is suitable for aqueous (water-based) solutions only. Do not use with organic solvents, strong acids, or strong bases.

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 Standard 80 Fabrication?

The Standard 80 fabrication uses precision UV-cured adhesive to bond high-purity quartz panels. This method delivers >80% transmittance across the UV-Vis-NIR spectrum while keeping costs accessible. The adhesive joints are optically transparent and spectrally neutral, making Standard 80 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 2.5 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.
