| MICROTEST modules 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. Windows XP/Vista software sets drive parameters and displays the stress/strain curve live on the computer screen. Loadcells from 2N to 5KN cover most applications, with extension rates from 0.005mm/min to 50mm/min. All stages have linear scales for elongation measurement and optical encoders for speed control. Options include three and four point bending clamps, fibre clamps and microscope mounting adaptors. All modules are controlled from Microtest tensile testing software and special versions can be manufactured to customers requirements. |

| Standard 200N stage |
|
| 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 slide 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 extended specimen length and stage travel.

| 200N stage with petri dish |
|
| 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. |

| 200N stage with peltier heating & cooling |
|
| 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. |

| 200N MEMS stage with piezo control |
|
| The piezo version of the 200N stage has an additional piezo motor fitted which allows very fine movement with step sizes as small as a few nm. Designed primarily for manipulating minature MEMS devices in the SEM this stage can be used for various applications and can be customised for specific specimens. |
