SILICON NITRIDE MEMBRANE WINDOWS FOR TEM ANALYSIS


Single Window Silicon Nitride TEM Grids
Our standard silicon nitride window grids for Transmission Electron Microscopy (TEM) 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).
The devices listed on this page are made as sample holders for electron or X-ray microscopy/spectroscopy applications. Please refer to our Nanopore Products page if you require devices for nanopore, genomics, proteomics or other bio-physics applications. Alternatively, please contact us via info@norcada.com and we would be glad to help with product selection.

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.

3×3 Window Array for TEM
The window array TEM grid has 9 evenly-spaced 0.1×0.1mm square windows (in a 3×3 array pattern) centered on a 200µm thick circular or octagon shaped silicon frame that fits inside a 3mm diameter circle. The window array allows the users to carry out several tests on the same TEM window device.

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. More information can be found here.
