The CANNON® PolyVISC® Automatic Glass
Capillary Viscometer combines automatic
sampling, viscosity measurement, viscometer
washing, and polymer solvent compatibility
to provide a convenient benchtop unit ideal
for dilute solution polymer viscosity analysis.
Both transparent and opaque samples can be
measured with the accuracy required by ASTM
D 2857. Infrared optical sensors are used for all
transparent samples and some opaque samples.
Thermal sensors are available upon request
for heavily opaque samples.
The PolyVISC utilizes a unique “air bath” technology to maintain excellent temperature control. Analyses are made
in an ultra-stable thermostatic air chamber (the AIRBATH®). The AIRBATH consists of an outer insulated chamber
enclosing a second, inner chamber, where the viscometer and sample are continuously bathed in a thermally stabilized
stream of air. Temperature is controlled within 0.01°C with advanced measuring electronics, thermoelectric cooling,
and controlling software. Because both the sample carousel and the viscometer are completely contained in the
AIRBATH, only the first sample requires a delay for thermal equilibrium. The AIRBATH also allows rapid temperature
and viscometer changes. Built-in thermoelectric cooling enables testing below 40°C without the need for
an external chiller.
