Product Name: 200 Mesh Copper Grids for Carbon Film (Round Holes) Product Code: WTMTW-150 Specification: Individual Grid

Product Description:

This product is a copper grid commonly used for transmission electron microscopy (TEM), serving as a sample holder. The grid is made of copper, and it is referred to as a “copper grid.” Depending on the material used, grids can also be called nickel grids, molybdenum grids, gold grids, nylon grids, etc. Copper grids are often used individually as “naked grids” in biological sample preparation. They can be used in combination with a microtome to pick up samples from the water trough and then undergo carbon coating before observation under the electron microscope. In most TEM sample preparations, to ensure the samples adhere to the grid, an organic film is coated on the grid, known as the “support film.” This type of grid with a support film is called “supported grid.” When the sample contacts the supported grid, it firmly adheres to the support film, preventing it from slipping out of the holes, allowing for observation under the electron microscope.

Carbon Support Film:

When samples are placed in the electron microscope, the supported grid may accumulate charges under electron beam irradiation, causing sample discharge, floating, jumping, and support film rupture. To mitigate these issues, carbon coating is applied to enhance the conductivity of the support film, achieving better observation results. Such supported grids with carbon coating are referred to as “carbon support film,” typically having a thickness of 10-20nm.
