e-VROC™ provides extensional viscosity data based on monitoring the sample flow through a microfluidic contraction within the cell. By measuring the pressure upstream and downstream of a contraction using the MEMS pressure sensors, the change in the flow is registered. 

With the same automated temperature and shear rate sweep capabilities as m-VROC™e-VROC™ will provide extensional viscosity measurements within a minute!
