Description

The C014WE is a quartz fluorescence flow cuvette with 1mm path length and four-way light optical configuration — all four vertical faces are polished to optical grade, enabling both standard UV-Vis absorbance and 90° fluorescence detection. With a 350ul internal volume (10 × 1 × 43 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. Equipped with an integrated PTFE stopcock valve for precise flow control during liquid introduction and drainage. Features a complex T-shaped flow cell configuration with dual PTFE-sealed ports and a vertical glass tube inlet, connected to a compact 1mm fluorescence measurement chamber at the base. The multi-port design enables simultaneous flow control and gas purging.

◆ Bioprocess Monitoring — real-time cell density, metabolite, and product concentration tracking

Why Four-Way Light?

Four-way light cuvettes have all four vertical faces polished to optical grade, enabling both standard absorbance measurements and 90° fluorescence detection geometry. The excitation beam enters through one face while emission is collected at right angles through an adjacent face — the standard configuration required by fluorimeters and spectrofluorometers.

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.

Why a PTFE Valve?

The integrated PTFE stopcock valve provides precise flow control for liquid introduction and drainage. PTFE is chemically inert and compatible with strong acids, bases, and most organic solvents, ensuring zero contamination or leaching during flow-through measurements. The valve allows controlled sample exchange without removing the cuvette from the instrument, enabling continuous-flow kinetics, titration experiments, and automated sample delivery workflows.

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, cap the cuvette, and run a blank before sample measurements.
