Gatan Disc Grinder

The disc grinder is an accurate and dependable tool for mechanically pre-thinning specimens with high quality and uniform thickness. The pre-thinning and polishing procedures reduce the overall time and improve the quality of the final specimen. The disc grinder produces parallel-sided samples quickly and easily and the larger micrometer dial displays the thickness in microns (µm).

Features:

• Lightweight grinder reduces maximum polishing pressure and specimen damage
• Achieve excellent control of specimen thickness with ultra-fine thread and pre-loading of the specimen drive screw
• Ensure uniformly thin specimens (5 µm accuracy) using large diameter polishing face with precise fit of the specimen mount

For transmission electron microscopy (TEM), the quality of the initial disc determines the quality of the final specimen. The thinner the starting disc thickness and the higher the uniformity is, the larger the final electron transparent area is. The problems most often encountered in trying to obtain thin discs are tapering of the cross-section, sub-surface specimen damage, and poor control of the final specimen thickness and uniformity.
