Extensional Viscosity

Ideal for studying the complex properties of fluids

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. 

Extensional Viscometer, e-VROC

As depicted in the image, the fluid experiences shear flow in the straight channel and then an almost constant extension in the contraction zones.
