Description

The C052CS3 is a quartz screw-top cuvette with 5 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 1.75 ml internal volume (10 × 5 × 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, eliminating adhesive joints entirely.

Spectroscopy Applications

◆ UV-Vis Absorbance Spectroscopy — quantitative concentration, kinetics, Beer–Lambert studies

◆ DNA / RNA Quantification — nucleic-acid purity checks at 260/280 nm

◆ Protein Assays — Bradford, BCA, Lowry, and direct A280 measurements

◆ Enzyme Kinetics — real-time substrate conversion and inhibition studies

◆ Water Quality & Environmental — COD, nitrate, phosphate, heavy-metal colorimetric tests

◆ Pharmaceutical QC — dissolution testing, drug concentration, stability monitoring

◆ Chemical Reaction Monitoring — reaction progress tracking via absorbance changes

◆ Teaching & Student Labs — durable quartz cells for undergraduate spectroscopy courses

Why Two-Way Light?

Two-way light cuvettes have two opposite polished faces that form the standard transmission path for absorbance measurements. The remaining two faces are frosted (ground), which blocks stray light from reaching the detector at oblique angles and improves measurement accuracy. This is the most common configuration for UV-Vis spectrophotometry.

Why Molded 83?

Molded 83 cuvettes are precision-molded from a single piece of quartz with no adhesive joints, achieving >83% transmittance. They withstand all common laboratory solvents, concentrated acids, and bases (avoid HF) — the most chemically resistant option available.

Usage Tips

Rinse with a compatible solvent (e.g., ethanol or the measurement solvent) before first use to remove any residual particles.
Do not use abrasive materials or brushes on the polished optical faces — wipe gently with lens tissue.
Withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid).
Store in the original protective case to prevent scratches on the optical windows.
For baseline correction, fill with your reference solvent, cap the cuvette, and run a blank before sample measurements.
