Electron Microscopy Grids, Mesh, and Films
Electron Microscopy Sciences TEM Window Pure Silicon, 25 µm, 5 nm
Pure Silicon TEM Windows feature imaging windows with 5 to 15 nm thickness, reducing background contribution and interference for higher contrast imaging. The membrane can be vigorously plasma cleaned to remove organic contamination, unlike traditional carbon grids. The elemental silicon composition of TEM Windows remarkably increases stability at high beam currents and at high annealing temperatures. With a minimal background signal, elemental analyses of samples containing nitrogen and/or carbon is possible by EDX and EELS. Nanoporous with pores from 10-60nm.
Dimensions: 25 µm
Thickness: 5 nm

Electron Microscopy Sciences Graphene Oxide Support film on Quantifoil R1.2/1.3, Cu 400 mesh
Graphene Oxide (GO) support film is a super thin (<1nm), naturally hydrophilic layer placed over the support film on grids. Pre-treatment of GO Support Films is unnecessary - by default, the hydrophilic surface spreads particles evenly across the grid. A hydrophobic surface can be achieved by heating in the air.
It works well with holey carbon, lacey carbon, and Quantifoil grid types, effectively spanning the gaps. It is less expensive than graphene to produce due to complexity of graphene manufacturing and has a better background contrast than graphene resulting in higher resolution. Nearly transparent in electron beam and barely visible under optical microscopes. Regular batch checking ensures correct coverage of monomers.
Note: plasma cleaning or glow discharge will damage the support film.
