Other available 300 mesh grids:

SPI Supplies also can offer 300 mesh TEM grids from other materials. However, note that these other grids are made from different art work and therefore, will be different than the art work at the top for this page. In general, these other grids are etched from metal foils and therefore have lower open areas and rougher grid bars (one might say, "not quite as nice"). But for some applications, there are no alternatives.
