Quartz 1mm Stoppered Cuvette, 430 µl, Molded 83, Two-Way Light, PTFE Stopper, Pack of Two, C012SS3
Description
The C012SS3 is a quartz stoppered cuvette with 1 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 micro 430 µl internal volume (1 × 10 × 43 mm chamber), the cell is compatible with most commercial spectrophotometers. Fabricated using Molded 83 (>83% transmittance) — precision-molded from a single piece of quartz for reliable performance with a wide range of laboratory solvents. The PTFE stopper seals the cuvette opening, preventing evaporation of volatile samples and protecting air-sensitive or hygroscopic solutions during measurement.

Spectroscopy Applications
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 cuvettes are assembled using optical-grade adhesive to bond precision quartz panels, achieving transmittance >83% at 200–2500 nm. This fabrication method delivers reliable optical performance at an accessible price point — ideal for routine measurements with a wide range of solvents. Molded 83 cuvettes withstand all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid). The one-piece molded construction eliminates adhesive joints, providing superior chemical resistance compared to adhesive-bonded cuvettes.
