Square mesh TEM grids – special metals

Square mesh grids are the most popular type of grid for TEM applications.

For specialised applications – including high temperature work – square mesh grids are available in mesh sizes 50 to 400 in molybdenum, titanium, aluminium and stainless steel.

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