Abstract

The invention relates to the technical field of sample fixing devices, and specifically relates to a sample fixing platform. The sample fixing platform comprises a base and a cylinder arranged on the base, wherein a plurality of sample placing positions are arranged at the upper end of the cylinder; and fixing parts for fixing samples are arranged on the sample placing positions. The invention also relates to a freeze scanning electron microscope containing the sample fixing platform. According to the sample fixing platform and the freeze scanning electron microscope containing the sample fixing platform provided by the invention, a plurality of fixing parts are arranged at the upper end of the cylinder, and a plurality of samples such as blades can be fixed simultaneously, so that the consumed time for experiments is short, the experiment efficiency is greatly improved, and the economic cost in the experimental process is also reduced.

Description

technical field [0001] The invention relates to the technical field of sample fixing devices, in particular to a sample fixing platform and a cryo-scanning electron microscope comprising the same. Background technique [0002] Cryo-SEM is a microscopic morphology observation method developed on the basis of scanning electron microscopy. Its resolution is between that of transmission electron microscopy and optical microscopy. It can directly perform microscopic imaging of metals, chemicals, and high-water biomedical materials. One of the important research tools in the field of life. The interior of the scanning electron microscope chamber is a vacuum environment. If a biological sample with high water content is directly placed in the sample chamber, it will cause the sample to lose water and deform, which will affect the original shape information. The technical level of the operator is high, and the repeatability of the experiment is poor. The cryo-scanning electron mic...
