The Hach TL2350 Benchtop Turbidimeter is engineered for exact and repeatable turbidity measurements critical in water quality monitoring, municipal water testing, and environmental compliance. Featuring:
This turbidimeter is widely adopted in environmental biotechnology and clinical diagnostics, playing a crucial role in bioprocessing quality assurance and water purity analysis. Its robust performance suits applications in synthetic biology research, molecular biology labs, and biopharmaceutical production pipelines that demand stringent particulate monitoring.
Note: An instrument-grade air or dry nitrogen source is required for the air purge system (not included). Prior factory testing guarantees performance to specifications.
