Lab Filtration & Purification


Separation technology is often an important element in laboratory-based research, development, analytics and diagnostics across all major applications and workflows. From the isolation of biologics in cell line development to sample preparation of waste water in epidemiology and the concentration of disease markers from human samples, Sartorius combines its wide range of application knowledge and innovative products to reduce specimen-to-report timelines and ensure efficient and easy filtration and purification processes.
