Available in two capacities – 100kN and 250kN, the robust manual wedge action self-centring grips are ideal for demanding tensile tests on composites, metals, and plastics over a range of temperatures: -80 to 250°C. The grips incorporate a moving body, driven by a worm gear drive, which closes the jaw faces together in a self-centring action to clamp the specimen. Furthermore, the symmetrical construction of the grip body provides even clamping of the specimen under load. Together, these features ensure accurate and repeatable specimen alignment, satisfying Nadcap AC7122-1 and AC7101. A range of accessories, including compression platens with lockable spherical seats, are available to attach specialised test fixtures to the grips. This means that a user can reconfigure a testing machine for different test types without needing to remove the grips. Also available are a range of jaw faces and a compatible temperature chamber. www.instron.co.uk
