SEM manual rotary holder enhancing sample stability equipped with entomological pin adapter

We present an SEM manual rotary holder equipped with an entomological pin adapter, which allows the free rotation of samples in three axes and guarantees appropriate stability. During imaging, the presented device allows for increased safety when working with fragile and valuable specimens (e.g., holotypes) while maintaining parameters at least as good as previously used techniques. The design of the solution allows it to be integrated with many SEM systems and commercial adapters, significantly increasing its usefulness and versatility. Simultaneously, it does not require additional accessories for manipulation during operation. Additionally, learning to use the proposed solution requires only minor experience. An interesting additional application of the SEM manual rotary holder is its possible usage in other microscopy systems, such as stereoscopic microscopes or even for sample preparation purposes for holding samples.
