Electron Microscopy Grids: General

Electron Microscopy grids are generally used in Transmission (TEM). A TEM grid is usually a flat disk with a mesh used to support thin sections of samples such as ultra thin sections or micro-samples.

The holes in the grids allow the electrons to pass through the sample. Grids are available in a wide variety of models and materials for various applications.

The standard diameter of the grids is 3.05 mm, but there are also special instruments that use different diameter versions (for example, 2.3 mm).

The most used grids are 200, 300 and 400 mesh square grids or Mesh
