Seeing Non Newtonian Behaviour from Newtonian Fluids?
Nov 09 2011
The formation of a film from absorbed proteins at the air-solvent interface falsely gives much higher viscosity values
and shear thinning behaviour on some viscometers. The VROC obtains a viscosity reading by measuring the pressure drop as a test fluid flows through a flow channel. RheoSense took this principle and created a dynamic microlitre-scale sample viscometer by adding microfluidics, and reducing the size of the device with MEMS manufacturing. As a result,
VROC® technology offers capabilities that are well beyond the limits of conventional viscometers. With samples volumes as low as 50μl and high (1,000,000 1/s) shear rates, the VROC range is available in the UK from Meritics.
