The e-VROCâ„¢ viscometer has the precision and accuracy of the m-VROC viscometer with the added capability of measuring apparent extensional viscosity. By monitoring the sample flow through a microfluidic contraction, the system measures the pressure upstream and downstream of a contraction using the MEMS pressure sensors and registers changes in the flow.
