Long Path Length Glass Cuvette 17.5mL (LAG-108)

Premium 50 mm Optical Glass Cells for Dilute Sample Spectroscopy

The LARK LAG-108 is a specialized, long path length macro spectrophotometer cell engineered for the quantitative analysis of low-concentration or highly dilute liquid samples. Fabricated from premium optical glass by Lark (France), this cuvette provides an extended 50 mm optical path length. It is ideal for environmental water testing, trace chemical analysis, and routine colorimetry where standard 10 mm cuvettes lack the sensitivity to detect faint light absorption.

Key Features

• Extended 50 mm Path Length: Five times longer than industry-standard 10 mm cells. This drastically improves absorbance sensitivity for trace-level analytes in accordance with Beer-Lambert’s Law.
• Optimized Vis-NIR Transmission: Purpose-built for high-accuracy performance from 340 nm to 2,500 nm, providing exceptional clarity across the entire visible and near-infrared spectrum.
• Two-Window Optical Design: Features 2 precision-polished windows optimized for direct, straight-through light beams, and 2 frosted side walls for fingerprint-safe handling.
• Evaporation-Resistant Protection: Ships with custom-fitting PTFE covers to securely contain large liquid volumes and prevent sample evaporation or dust contamination during testing.
