Viscometer: Viscometer ViscoStar™

Wednesday, April 3, 2013

On-line differential viscometer with unparalleled signal-to-noise ratio, low baseline drift and noise. Accepts external signals for zero, purge, and recycle. Ethernet and USB communications, full color LCD display conveys data at a glance. Transducer Protection System (TPS) and user-selectable delay volumes also included!

Wyatt Technology in collaboration with Professor Skip Rochefort's group at Oregon State University used a DAWN EOS, an Optilab rEX and a ViscoStar to measure the intrinsic viscosity and Mark-Houwink-Sakurada (MHS) behavior of Hyaluronic Acid (HA). Unusual MHS behavior was demonstrated, perhaps helping explain the large variation in HA MHS coeffiecents that have been reported in the literature.
