Viscotek Unveils Automated Relative Viscometer System

Houston-based Viscotek reports its new Automated Relative Viscometer (ARV) System frees the
operator to concentrate on testing rather than preparing samples for determining relative,
inherent, intrinsic, specific and absolute viscosity of dilute polymer solutions, in addition to
measuring their molecular weight all in an efficient, precise and safe process.

The system features the dual-capillary Viscotek Relative Viscometer; the Vortex Integrated
Autosampler/ Autopreparation Module for fully automated sample preparation and delivery; and ETA
Software for data acquisition, processing and reporting, and complete system control.
