This post will help guide you through pinching (pincer) grip setup and operation on your universal testing machine. Pinching grips are low capacity tensile grips used to grip small size samples.
Pinching grips may be supplied as a manual version, pneumatic version, or with a chain mount for flexible positioning. For further information on ADMET pinching grip options, click here.
