EnviroScope SPM

EnviroScope

The Digital Instruments EnviroScope Atomic Force Microscope (ESCOPE) combines AFM imaging with environmental controls and hermetically sealed sample chamber to perform contact, lateral force, and TappingMode atomic force microscopy in air, vacuum, or a purged gas, as well as a heating environment. With advanced environmental capabilities, users can observe sample reactions to a variety of complex environmental conditions while scanning.
