Quartz 10mm square-bottom fluorescence flow cuvette, 3.5ml, Molded 83 (>83% transmittance). Four-Way Light. 190–2500 nm. SKU: C104WE1.
Description
The C104WE1 is a quartz square-bottom fluorescence flow cuvette with 10mm 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 3.5ml internal volume (10 × 10 × 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. Showcases a T-shaped flow cell similar to C104WE but with a square-bottom chamber design, featuring dual PTFE-sealed ports and vertical tube. The square-bottom geometry provides better optical alignment with standard sample holders.

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.
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.
