EM ACE900 Freeze Fracture System

Description

The EM ACE900 from Leica Microsystems is a sophisticated, integrated system for preparing samples using freeze-fracture and freeze-etching methodologies, primarily for TEM and SEM analysis. It functions under high vacuum conditions and includes a precision three-axis movable microtome for fracturing cryogenically frozen specimens. A key characteristic is its capacity for low-angle electron-beam coating combined with sample rotation. This allows for the deposition of extremely thin, continuous metal or carbon replicas of the fractured surface. This technique aims to preserve and expose the ultrastructure of membranes and cellular components. The system is engineered to supply the controlled environment and precision required for generating high-fidelity replicas suitable for detailed structural investigation.
