Description

Technical Field

[0001] The utility model relates to the technical field of slice staining, in particular to an ultra-thin slice staining device for a transmission electron microscope. Background Art

[0002] The resolution of a transmission electron microscope is much higher than that of an optical microscope, reaching 0.1 to 0.2 nm, and the magnification is tens of thousands to millions of times. It can deeply observe the fine structure of a sample and is an important analytical method in the fields of physics and biology, such as cancer research, virology, materials science, and nanotechnology.
