莱西碳电影300网黄金Grids (Pack of 50)

Lacey carbon films are similar to the holey carbon films in that they have open areas but because of the fine lacey mesh structure they offer a greater percentage of open area in comparison (see micrograph). They provide the thinnest possible support film while maintaining adequate strength and give practically no background interference in the TEM. As much of the specimen is unsupported, these films are appropriate for use where a structure free background is of importance. Lacey carbon films are particularly suitable for studying some nanotubes, acicular crystals and biological/materials specimens
