The Polymer Laboratories PL-BV 400HT Bridge Viscometer is a detector for the online measurement of viscosity in GPC/SEC. The combination of refractive index (RI) and viscosity detection provides accurate molecular weight determination for all polymer types based on the Universal Calibration principle, as well as valuable branching information not otherwise accessible from a concentration detector alone.
