Description

The C302CA is a quartz (fused silica) standard cuvette with 30 mm path length and two-way light optical windows, designed for UV-Vis and NIR spectrophotometry across 190–2500 nm. The two-way configuration transmits the beam through two opposing polished faces while the frosted sides minimize stray light and internal reflections. Fabricated using Sintered 80 — a sintering process at 600 °C that fuses quartz components without adhesive — delivering >80% transmittance with good chemical resistance. A cost-effective choice for routine laboratory work. Includes a PTFE cap for chemical-resistant sealing. Supplied as a pack of two for cost-effective parallel or comparative experiments.

Applications

◆ UV-Vis absorbance spectrophotometry across 190–2500 nm

◆ Beer-Lambert law concentration determination and calibration curves

◆ Pharmaceutical dissolution testing and active ingredient quantification

◆ Environmental water quality analysis (COD, BOD, nitrate, phosphate)

◆ Chemical kinetics and reaction rate monitoring

◆ Teaching laboratories and routine analytical measurements

Why This Cuvette?

The two-way light configuration (two polished, two frosted) provides clean absorbance with minimal stray light. The frosted faces reduce internal reflections, improving baseline stability — particularly important for low-absorbance measurements. The 30 mm path increases sensitivity by 3× compared to 10 mm (Beer-Lambert: A = εlc), improving detection of dilute analytes.

Usage Tips: Handle by the frosted (non-optical) sides to avoid fingerprints. Fill to at least 15 mm above beam center. Clean with spectroscopic-grade solvent and lint-free tissue. For aqueous samples, rinse with DI water first. Avoid prolonged ultrasonic cleaning. Store upright in original case. Compatible with Shimadzu, Agilent, PerkinElmer, Thermo Fisher, JASCO, and most UV-Vis spectrophotometers.
