SILICON NITRIDE MEMBRANE WINDOWS FOR TEM ANALYSIS

Norcada’s standard TEM window with a single membrane at the centre of the frame.
Norcada’s TEM window array with 9 windows on a single frame for multiple analyses.

Single Window Silicon Nitride TEM Grids

Our standard silicon nitride TEM window grids are available with 5nm, 10nm, 30nm, 50nm, or 100nm thick square membrane windows centered on 200μm thickness silicon frames. The TEM window frames are circular or octagon shaped and fit inside a 3.0mm diameter circle. The silicon nitride membrane is low stress and robust. All of our TEM windows are packaged in 2″x2″ gelpaks (10 devices per pack).

Location-Tagged Holey Nitride TEM Grids

Location-tagged holey TEM nitride windows are similar to regular TEM grids but with micro-size pores over the membrane area.  In addition, it has location markings in both X and Y directions along the edges of the holey membrane,  allowing end users to track the locations on the membrane during their TEM work.

Nano and Micro Porous Membranes on TEM Grids

 

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