Malvern’s Dilute Solution Viscometer (DSV) unit provides an accurate and safe method to determine the intrinsic viscosity of various polymers. The semi-automated sample preparation and automated analysis features of the DSV limit the handling of hazardous solvent and exposure while minimizing user error. In this webinar, the design and features of the DSV will be presented, highlighted with some example data.
