ABSTRACT:
A scanning electron microscope permitting observation of raw biological specimens containing moisture. A vessel accommodating water supplied to the specimen is formed. A passage is formed in the specimen chamber of the microscope to convey the liquid from the vessel to the specimen. A pipe for introducing a gas such as air is connected with the passage. The introduced gas leaks around the specimen after flowing through the passage to prevent the liquid from freezing in the vessel and in the passage when the specimen chamber is evacuated to a vacuum.
