Quartz 20 mm standard cuvette for absorbance spectroscopy (190–2500 nm). 7 ml volume, Sintered 83 fabrication (>83% transmittance), two-way light windows, PTFE cap. SKU: C202CR9
Description
The C202CR9 is a quartz (fused silica) standard cuvette with 20 mm path length and two-way light optical windows, designed for UV-Vis and NIR spectrophotometry across 190–2500 nm. The two-way light configuration transmits the beam through two opposing polished optical faces while the two frosted sides minimize stray light interference and internal reflections, delivering clean baseline performance for absorbance measurements. Fabricated using Sintered 83 — a high-temperature sintering process at 600 °C that fuses quartz components without adhesive — this cuvette achieves >83% transmittance with excellent chemical resistance to acids, bases, and organic solvents. The sintered bond withstands repeated thermal cycling without degradation. Includes a ptfe cap for chemical-resistant sealing. Supplied as a pack of two for cost-effective parallel or comparative experiments.

◆ Chemical kinetics and reaction rate monitoring
◆ Teaching laboratories and routine analytical measurements
Why This Cuvette?
The two-way light configuration (two polished optical faces, two frosted sides) provides clean absorbance measurements with minimal stray light. The frosted faces reduce internal reflections and scattering, improving baseline stability and signal-to-noise ratio — particularly important for low-absorbance measurements near the detection limit. The 20 mm path length increases measurement sensitivity by 2× compared to a standard 10 mm cuvette (Beer-Lambert law: A = εlc), significantly improving detection limits for dilute analytes and trace-level concentrations.
Usage Tips: Handle the cuvette by its frosted (non-optical) sides to avoid fingerprints on the polished windows. Fill to at least 15 mm above the beam center height to avoid meniscus effects in the light path. Clean with spectroscopic-grade solvent and lint-free tissue after each use. For aqueous samples, rinse with deionized water first, then solvent. Avoid prolonged ultrasonic cleaning which can stress the optical bonds over time. Store upright in the original case when not in use. Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, and most commercial UV-Vis spectrophotometers with standard 12.5 mm cuvette holders.
