ViscoStar® Differential Viscometer for GPC, Wyatt Technology Corporation (CAT#: STEM-LE-2014-LC)

ViscoStar® Differential Viscometer for GPC is used with the DAWN® or miniDAWN™ in SEC-MALS analysis for determination of polymer and protein molecular conformation, branching ratio and Mark-Houwink-Sakurada parameters. It may also be applied for traditional online intrinsic viscosity, such as Universal Calibration or Mark-Houwink-Sakurada analysis of molecular weight and size, all supported by Wyatt's ASTRA® chromatography software.
