The hand specimen holder is an important tool for target preparation, it minimises the risk of over-grinding and the microscopic control effort.
The hand specimen holder is designed for ground and thin sections (holder or insert H). The vernier setting makes it possible to achieve a defined material removal (distance between 2 graduations of the scale = 0.02 mm).
The locking ring prevents the preset dimension from being adjusted during the grinding process. The very hard ceramic ring prevents over-grinding and ensures reliable removal up to the desired level.
