Description

The C102CE13 is a precision quartz micro volume cuvette with 10 mm path length and two-way light optical windows, designed for UV-Vis spectrophotometry (190–2500 nm). The two-way light configuration transmits the beam through two opposing polished optical faces, delivering clean baseline performance for absorbance measurements. This cuvette reduces the required sample volume to 0.35 ml (350 µl) — saving 90% compared to a standard 3.5 ml cell — by using internal quartz masking walls that narrow the chamber to ~1 mm width while maintaining the full 10 mm optical path. Fabricated using Molded 83 (>83% transmittance). Includes a PTFE stopper for chemical-resistant sealing and evaporation prevention. Compatible with all standard spectrophotometers regardless of beam height.

Why PTFE Stopper?

The PTFE stopper provides a secure, chemical-resistant seal that prevents solvent evaporation and protects samples from atmospheric contamination. PTFE (polytetrafluoroethylene) is inert to virtually all laboratory chemicals, making this stopper suitable for use with aqueous buffers, mild organic solvents, and air-sensitive samples. The stopper enables safe inversion for gentle mixing without leaks, and maintains stable sample concentrations during extended kinetic measurements where even minor evaporation would compromise results.

Applications

◆ UV-Vis spectrophotometry (190–2500 nm)

◆ Protein (A280) & nucleic acid (A260) quantification

◆ Enzyme kinetics & reaction monitoring

◆ Pharmaceutical QC & purity testing

◆ Environmental & water quality analysis

◆ Chemical analysis with limited sample (0.35 ml)

Why Micro Volume?

Internal quartz masking walls narrow the measurement chamber to ~1 mm while maintaining the full 10 mm optical path (Beer–Lambert law: A = εlc). This saves 90% of sample compared to a standard 3.5 ml cuvette, making it ideal for precious biological samples, expensive reagents, or limited column fractions. Unlike ultra-micro cuvettes with raised platforms, the micro volume design keeps the sample at full column height — compatible with all spectrophotometer beam heights (8.5 mm, 15 mm, or 20 mm) without verification.

Why Molded 83 Construction?

Molded 83 is the premium fabrication method: the cuvette is integrally fused as a single piece with no adhesive or joints. This eliminates solvent attack points and enables operation up to 1200 °C — far exceeding sintered (600 °C) or glue-assembled (200 °C) alternatives. The one-piece construction delivers a path length variation of just ±0.02 mm, ensuring the highest level of reproducibility. With transmittance >83%, Molded 83 is the gold standard for demanding research applications.

Usage Tips: Handle by non-optical surfaces only — avoid touching polished windows. Rinse immediately after use with an appropriate solvent. Molded 83 construction withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid). Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Hitachi, and most commercial spectrophotometers.
