Description

The C102SE1 is a quartz stoppered cuvette with 10 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 standard 3.5 ml internal volume (10 × 10 × 43 mm chamber), the cell is compatible with most commercial spectrophotometers. Fabricated using Molded 83 (>83% transmittance) — the cuvette body is integrally fused as a single piece with no adhesive joints. The PTFE stopper seals the cuvette opening, preventing evaporation of volatile samples and protecting air-sensitive or hygroscopic solutions during measurement.

Spectroscopy Applications

◆ UV-Vis absorbance spectroscopy

◆ Quantitative chemical analysis

◆ Enzyme kinetics & reaction monitoring

◆ DNA / RNA / protein quantification

◆ Beer–Lambert law measurements

◆ Solvent & reagent quality control

◆ Sealed volatile / air-sensitive sample measurement

◆ Long-duration kinetic runs (evaporation protection)

Why Two-Way Light?

The two-way configuration polishes two opposite vertical faces to optical grade — the standard geometry for UV-Vis absorbance (transmission) measurements. The excitation beam passes through one polished face, traverses the sample path, and exits through the opposite polished face to the detector. The two non-polished (frosted) faces reduce stray-light scatter, improving photometric accuracy. This is the most common and cost-effective configuration for routine absorbance work.

PTFE Stopper

The PTFE stopper creates an airtight seal over the cuvette opening, preventing solvent evaporation during extended measurements and protecting air-sensitive or hygroscopic samples from atmospheric exposure. PTFE is chemically inert to virtually all laboratory solvents and contributes no background absorbance or fluorescence, ensuring clean spectra. The stopper fits snugly by friction and can be removed and replaced one-handed for rapid sample exchange. Ideal for volatile solvents, long kinetic runs, and any application where maintaining sample concentration and composition is critical.

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. Dimensional tolerance is ±0.02 mm. The monolithic construction withstands all common laboratory solvents, concentrated acids, and bases; avoid HF (hydrofluoric acid). With transmittance >83%, Molded 83 is the gold standard for demanding research.

Usage Tips: Handle by non-optical surfaces only — fingerprints on polished faces introduce scattering artifacts. Ensure the stopper is fully seated before inverting or transporting the cuvette. Molded 83 construction is withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid). Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, Hitachi, Horiba, Edinburgh Instruments, and most commercial spectrophotometers.
