Note:
• 1 Pa = 10 dyne/cm2
• Viscosity Range is given at rotational speed of 10 RPM
• 5xHB is the highest torque range available
• Not for use with DV-E Viscometers
M = 1 million cP = Centipoise
K = 1 thousand mPa•s = Millipascal•seconds
Pa = Pascal
Special Considerations
In taking viscosity measurements with the DVNext Rheometer, there are two considerations which pertain to the low
viscosity limit of eective measurement.
• Viscosity measurements should be accepted within the equivalent % Torque Range from 10% to 100% for
any combination of spindle/speed rotation.
• Viscosity measurements should be taken under laminar flow conditions, not under turbulent flow
conditions.
