TEM Window Grid Membrane Strength
EMS Catalog #76042 Series TEM Window Grids
Membrane Window Strength - Differential Pressure Tolerance
Silicon Nitride
All our membrane types and membrane area configurations have been robustness tested by application of differential pressure. In these tests, the membrane was oriented such that differential pressure forced the membrane against the chip frame. In the opposite orientation where the membrane would be delaminated from the chip frame, the pressure tolerance would be several times lower.
All values below are the maximum tolerated differential pressure reported as mean +/- standard deviation (n = 3), in units of PSI.
