Sample Preparation Laboratory

Head of the Laboratory: Dr. George Levi. Office: +972-3-640-9205. Email: georgelevi@tauex.tau.ac.il.

The laboratory main goal is to produce bulk sectioned specimens for analytical investigation purposes.

The laboratory utilizes high precision tools for the mechanically cutting, grinding and polishing of a wide range of solid materials. Thinned specimens are brought to electron transparency using a precision ion polishing system.

For further information including how to get access to the Lab tools please, contact the Lab Manager.
