Using the very latest MEMs technology and processing techniques, we can now offer an array of holes, 2Ám in diameter on 4 Ám centers.
The entire area of the membrane window is "holey" and the the array of holes covers the membrane area in its entirety.
Quantitatively, there are 113x113 rows/columns for a total number of 12,545 holes per membrane.
There is a staggering of the rows for increased mechanical strength. The outside frame will fit comfortably in any TEM
grid holder designed for 3.05 mm diameter grids.
The typical TEM grid has a thickness of 30-50 Ám whereas these grids are 200 Ám thick. For most TEM users
this larger thickness presents no problems what so ever. However, for the first time user make sure you do
not "force" the holder too tight. If you should be one with a holder that is just "too snug", we suggest
contacting your TEM vendor supplier since they would have information about how the holder could
be modified to more comfortably "take" this thicker grid. But as mentioned earlier, most users report no
difficulties whatsoever in the use of these somewhat thicker grids.
