The new RheoCapillary from ATS RheoSystems is an advanced laboratory capillary rheometers for the determination of the flow behaviour of a wide range of materials and benefits of a twinbore system.

The new RheoCapillary from ATS RheoSystems is one of the most technically advanced laboratory capillary rheometers for the determination of the flow behaviour of a wide range of materials and the benefits of a twinbore system.

The computer controlled instrument offers testing abilities to measure shear viscosity, extensional viscosity, wallslip, melt fracture and rupture with a variety of dies and accessories.

The two level software offers standard test control functionality as well as scientific evaluation capabilities for a better understanding of the data.

Its ergonomic design allows easy access and experimentation.

The Twin Bore Design allows fast measurements and high flexibility.

The RheoCapillary showed the best precision in round robin tests (NPL London).

High Precision is achieved through the use of tungsten carbide dies, multi-point calibration and high precision transducers and amplifiers.

Also featured are Extensional Viscosity Measurement by convergent flow, hyperbolic die or precision melt strength system with optional extrudate profile measurement.

In addition, High Temperature Uniformity is maintained across the entire two samples.

Advanced Software for test control handles Shear Viscosity, Extensional Viscosity, Wall Slip, Degradation, Melt Fracture and Rupture, First Normal Stress Difference, and Stress Relaxation.

Advanced Software for data analysis deals with Model Fitting, Material Database, MWD calculation, Flow Simulation and Error Assessment of Experiment, Direct Data Export into Flow Simulation, and Excel Compatibility.
