Micro-Porous Membranes on TEM Grids

The micro-porous membranes come with a range of different pore sizes arrayed on a square lattice with different spacing (pitch) for different designs. The hole array area is centered on the square membrane, and the membrane is centered on the frame of the standard TEM grid.  The image below shows hole array for  model NH050A1032 type micro porous membrane on TEM size grid.

Microporous Silicon Nitride Membranes on 5x5mm Silicon Frames:

Our standard holey silicon nitride membranes all have a single square membrane window centered on a 200µm (NX series) thickness square silicon frame.  The membrane has a holey pattern with a regular pitch which vary from design to design. The silicon nitride membrane is fabricated with low stress (<250MPa) silicon nitride and is very robust. All of our silicon nitride membrane window devices are packaged individually in gel capsules.
