Description

The C202WS is a quartz flow cuvette with 20 mm path length and two-way light windows (two polished optical faces for standard UV-Vis absorbance geometry), holding 2.6 ml of sample. The cell measures 12.5 × 22.5 × 24 mm externally with an internal chamber of 10 × 20 × 13 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. Integrated quartz tube flow cells have inlet/outlet tubes fused directly into the cell body — no adhesive joints, no removable fittings. This monolithic construction eliminates the most common failure point (glue degradation at tube joints) and provides exceptional chemical resistance and thermal stability. Simply connect tubing to the protruding quartz ports.

Why Molded 83 Fabrication?

The Molded 83 fabrication creates a monolithic fused-quartz cell from a single block — no adhesive joints, no bonding layers. This delivers >83% transmittance and complete resistance to all common laboratory solvents, concentrated acids, and bases (avoid HF). The seamless construction eliminates leakage risks and withstands repeated thermal cycling, making Molded 83 the premium choice for demanding flow applications.

Usage Tips: Connect standard laboratory tubing (silicone, PTFE, or Tygon) to the quartz tube ports. For integrated-tube cells, slip tubing over the protruding quartz tubes and secure with tubing clamps. Prime the cell slowly to eliminate air bubbles from the optical path. Flow rate should be adjusted to achieve laminar flow — typically 0.5–5 ml/min for standard cells. The 20 mm path length follows Beer-Lambert law: A = εlc, so absorbance scales linearly with path length and concentration. Clean by flushing with appropriate solvent, then deionized water. Avoid sharp bends in tubing near the cell to prevent stress on quartz connections.

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.
