Request InfoMalvern Panalytical Ltd.Malvern Instruments Ltd. has launched the Zetasizer Nano ZSP for measurement of zeta potential, or electrophoretic mobility of proteins. The dynamic-light-scattering system is a single compact unit that includes protein mobility measurement software. The new version of Zetasizer software also enables a new type of measurement – microrheology, a dynamic light-scattering-based optical technique that allows rheological characterization of weakly structured and highly strain-sensitive materials using only microliter sample volumes. Applications include measuring the viscosity of...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueViolet Laser DiodesThe HL40173MG and HL40175MG laser diodes from Ushio are 600-mW electrostatic discharge-resistant violet devices.
