The PolyVISC is a fully automated, benchtop capillary viscometer with an 11 position sample handler for unattended processing and testing of of dilute solution viscosity of polymers in organic solvents and aqueous solutions. A special coating permits testing with highly aggressive solvents, including concentrated sulfuric acid. Both transparent and opaque samples can be measured with the accuracy required by ASTM D 2857 and many other application-specific methods.
The ultra-stable thermostatic air chamber provides temperature control from 20°C to 135°C within ±0.01 °C (with available options). Because both the sample carousel and the viscometer are completely contained in the thermostatic air chamber, only the first sample requires a delay for thermal equilibrium.Built-in thermoelectric cooling enables testing below 40°C without the need for an external chiller.
The semi-automated Solution Preparation System (SPS) uses gravimetric (weight-to-weight) rather than volumetric methodology to prepare polymer solutions for relative viscosity measurement.
