Quartz 10mm Long-Neck Cuvette With Transition Section, 3.5ml, Molded 83, Two-way Light, 1pc/ea, C102WS2

The C102WS2 is a quartz long-neck cuvette with transition section with 10mm path length and two-way light optical configuration — two opposite vertical faces are polished to optical grade, forming the standard transmission geometry for UV-Vis absorbance measurements. With a 3.5ml internal volume (10 × 10 × 93 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. The upper tube section is made of glass, while the lower optical body is precision-crafted from high-purity quartz. The visible bulbous transition section where the glass tube meets the quartz cuvette body creates a smooth, sealed junction that minimizes turbulence, reduces bubble trapping, and ensures reliable continuous flow operation.

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.
