Advanced Hydraulic Wedge Action Grips
2742 and 2743 Series
-
The Instron advanced hydraulic wedge action grips deliver controlled, constant gripping force using an external hydraulic supply across static and dynamic testing. They support capacities up to 600 kN (static) and 500 kN (dynamic), with interchangeable jaw faces for round or flat specimens. The design ensures jaw face positions remain fixed during gripping (eliminating preload), compensates for changes in specimen thickness, and is ideally suited for use with metals, composites, and plastics.

Capillary Rheometers
-
Plastics are amazing materials with the unique ability to flow when heated to relatively low temperatures. They can be formed into a wide variety of shapes and tailored for many different applications. However, their flow properties during this process are complex and affected by many parameters. Instron® provides comprehensive and effective testing solutions in plastics applications and industries through the CEAST SmartRHEO Series. This capillary rheometer simulates the process conditions, measuring the plastic materials flow behavior that characterizes the rheology of materials.
