Quartz 5mm Cuvette With Stopper, 875ul, Sintered 83, Four-Way Light, Stopper, 1pc/ea, C054SS

The C054SS is a quartz cuvette with stopper with 5mm 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 875ul internal volume (5.5 × 5.5 × 28 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. The PTFE stopper provides an airtight friction-fit seal that prevents evaporation and protects air-sensitive analytes. Showcases a frosted-top cuvette design with a distinctive white PTFE stopper that provides airtight sealing. The four-window body with clear optical surfaces and the removable stopper design enable easy sample loading and vapor-tight operation.

• 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, cap the cuvette, and run a blank before sample measurements.
