Quartz 2mm Large Screw Neck Cuvette, 0.7ml, Molded 83, Two-way Light, Screw Cap, 1pc/ea, C022TS2

The C022TS2 is a quartz screw-top cuvette with 2 mm 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 0.7 ml internal volume (10 × 2 × 54 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 PTFE-lined screw cap threads securely onto the cuvette, providing a leak-proof seal that prevents evaporation of volatile solvents and protects air-sensitive samples. The threaded closure allows safe inversion mixing and sample transport without spills.

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.
