Overview

The e-VROC® RheoSense Extensional Viscosity Viscometer is a cutting-edge tool specifically designed to optimize industrial processes by providing highly accurate extensional viscosity data. Unlike traditional shear-based viscometers, the e-VROC® focuses on extensional viscosity, a crucial property for many polymer solutions and materials that experience stretching or elongation during processing. This makes it an essential instrument for industries that rely on polymer processing, such as plastics manufacturing, coatings, and food production.

Key Features

MEMS pressure sensors:

The e-VROC® RheoSense Extensional Viscosity Viscometer features a cutting-edge design that incorporates four monolithically integrated MEMS (Micro-Electro-Mechanical Systems) pressure sensors. These sensors are strategically placed to measure the pressure upstream and downstream of a contraction within the system, ensuring that the flow behavior of the polymer solution is accurately and precisely registered throughout the testing process.

RheoSense’s patented VROC® technology:

The e-VROC® RheoSense Extensional Viscosity Viscometer stands out from other methods of extensional viscosity measurement by offering the unique capability to measure extensional viscosity at high extensional rates while simultaneously capturing shear viscosities. This dual measurement capability is crucial for understanding the full rheological behavior of polymer solutions and materials under different processing conditions.
