200N compression & horizontal bending stage for SEM
MICROTEST 200N stages have been specifically designed to allow real time observation of the high stress region of a sample with an SEM, optical microscope, AFM or XRD system. With dual threaded leadscrews the centre of the specimen stays centrally located. Loadcells from 2N to 200N cover most applications, with extension rates from 0.1mm/min to 15mm/min. All stages have linear scales for elongation measurement and optical encoders for speed control. Windows software sets drive parameters and displays the stress/strain curve live on the computer screen. Options include three and four point bending clamps, fibre clamps and microscope mounting adaptors. Stages are controlled from our Microtest tensile testing software and special versions can be manufactured to customers requirements.

The 200N tensile stage uses miniature 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 both 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. Travel is 10mm by default with 20mm optionally available. Custom versions are available with heating/cooling, extended specimen length and stage travel.
200N stage with Peltier heating & cooling
The heating and cooling version of the 200N stage has been designed to provide temperature control from -20°C to +160°C. 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.
