Description

The C202WS1 is a quartz micro-volume flow cuvette with 20 mm path length and two-way light windows (two polished optical faces for standard UV-Vis absorbance geometry), holding 64 ul of sample. The cell measures 12.5 × 12.5 × 35 mm externally with an internal chamber of 10 × 10 × 33 mm. Inlet and outlet ports enable continuous sample flow for real-time monitoring applications. 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. Micro-volume flow cells minimize sample consumption while maintaining full optical-path performance. The reduced chamber volume allows faster sample turnover, sharper concentration transitions, and lower dead volume — critical for precious samples, micro-flow injection analysis, and coupling with micro-bore chromatography systems.

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: The micro-volume design requires careful priming to eliminate air bubbles from the optical path. Use a syringe or low-pulsation pump to fill the cell slowly. Ensure all tubing connections are secure before starting flow. The small chamber volume means fast response time but also higher sensitivity to blockages — pre-filter samples if particulates are present. Clean with spectroscopic-grade solvent between sample types. The 20 mm path length follows Beer-Lambert law: A = εlc.

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.
