Quartz 20mm Large-Capacity Large-Area Optical Sample Cell, 35ml, Sintered 83, Two-way Light, No Cap, 1pc/ea, C202CR2

The C202CR2 is a quartz large-capacity large-area optical sample cell with 20mm 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 35ml internal volume (43 × 20 × 50 mm chamber), the cell is compatible with most commercial spectrophotometers. Fabricated using Sintered 83 (>83% transmittance) — high-temperature sintered to fuse quartz panels without adhesive. Showcases an oversized rectangular cuvette body (43mm x 20mm x 50mm, 47mm wide x 52mm tall) with massive 35ml capacity, featuring the ‘Q’ marking and open-top design for large-volume optical measurements.

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.
• Compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone).
• Store in the original protective case to prevent scratches on the optical windows.
• For baseline correction, fill with your reference solvent, and run a blank before sample measurements.
