The specimen grip for highly ductile plastics and elastomers

These grips are primarily used for testing highly ductile plastics and elastomers. The pincer principle produces a strong increase in gripping force during the test.

Advantages & features

Function description


  • Secure specimen gripping through gripping force increasing proportionally to tensile force
  • The lateral mobility of the pincer grips allows specimens always to be loaded centrically to the test axis.
  • Ergonomic, open design for fast, easy specimen insertion and clamping
  • The grips are easy to operate in a temperature chamber and reach the test temperature quickly thanks to their very low mass.

Function description

The pincer grip is a double actuator grip. The pincer grip is opened and closed via a clamping lever.

The prestressed spring holds the specimen grip open for specimen insertion. If the specimen grip is closed, the prestressed spring generates the required gripping force.

The gripping force is increased proportionally by the pincer principle as the tensile force increases. This ensures automatic retightening for specimens prone to shrinkage.
