Quartz 10mm Square-Bottom Fluorescence Flow Cuvette, 3.5ml, Molded 83, Four-Way Light, 1pc/ea, C104WE1

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.

• 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.
