Square mesh TEM grids

Square mesh TEM support grids are the most popular type of grid for routine transmission electron microscopy (TEM) applications.

For routine TEM use they are available in mesh sizes from 50 to 600 in copper, copper with rhodium, gold and nickel.

For specialised applications including high temperature work we also offer these TEM grids in molybdenum, titanium, aluminium and stainless steel. See: square mesh grids – special metals.
