Single Tilt Straining Holders

Mechanisms of deformation in metal and polymer samples, such as grain-boundary sliding, grain rotation, and strain-induced diffusion, can be studied in situ in the TEM by means of Gatan's selection of straining holders. All of these side-entry, single tilt holders allow elongation at constant rates of electron-transparent specimens in the range of 0.01 µm/sec to 1.0 µm/sec. Elongation can be stopped and restarted at will with a push-button hand control.

The Model 654 Single Tilt Straining holder is designed for experimentation at ambient temperature.

The Model 671 Single Tilt Cooling holder is cooled by liquid nitrogen in a vacuum-insulated reservoir having sufficient cooling capacity for eight hours of operation at the minimum specimen temperature of about -170°C. Temperature stability is better than ±1°C in the -170°C to -130°C range.

All straining holders are equipped with a chart-recorder output (1µm/mV), located near the rear of the strain-control unit for recording the elongation history of the specimen.

Available Straining Holders from Gatan:

Please note: Tilt ranges of specimen holders vary according to the manufacturer, model, polepiece, and the presence of in-gap accessories of the TEM used. When ordering, please specify the TEM make, model, polepiece, configuration of the EDX detector (if any), and local voltage requirements.

Gatan manufactures a wide variety of analytical, cooling, heating, straining, and other specialty or custom holders for most microscope makes and models. Contact your local Gatan representative for more information about specific holders and microscope configurations.
