In-Situ Tensile Testing

Dual screw tensile stage for XRD, Optical & Synchrotron

The dual leadscrew stage has been designed to allow both transmitted and reflected illumination and can be fitted to an optical microscope, XRD system or Synchrotron. Supplied with feet the stage can stand vertically like a conventional tensile tester or with the feet removed it will sit flat on a bench or optical microscope stage. Versions with maximum loading to 2kN or 5kN are available, with optional loadcells of 200N, 500N and 1kN. Sample clamps are removable allowing easy customisation and the fitting of special clamps for different samples. We can supply fibre clamps, three and four point bending clamps and clamps to hold specifically shaped specimens. Optionally the stage can be supplied with temperature controllers and either heated or heated and cooled specimen clamps with a variable temperature range of -150C to 550C.
