The 200N tensile stage uses standard minature loadcells in the range 2N to 200N. Samples are mounted horizontally, clamped to a pair of jaws and supported on stainless steel sliding bearings. A dual threaded leadscrew drives the jaws symmetrically in opposite directions, keeping the sample centred in the field of view. The 200N module is ideally suited for use with an SEM, optical microscope or AFM and will easily fit on most stages. Custom versions are available with heating/cooling, extended specimen length and stage travel.
A version of the 200N stage is available to test specimens while submerged in a liquid (as shown on the right). Specimens are prepared and mounted to the jaws away from the stage and then moved across on a special transfer jig. As an option a peltier temperature controller can be fitted to set the liquid temperature between 10C and 50C. Observation of the specimen would normally be by optical microscope fitted with a submersible lens.
The heating and cooling version of the 200N stage has been designed to provide temperature control from -20C to +160C. A temperature controlled pad is located directly under the specimen and temperature is set using a small peltier element. System control and water cooling is from the Deben Coolstage control system which has a self contained water chiller and allows accurate temperature control with either keypad or PC control.
