Electron Microscopy Sciences TEM Window Grid Silicon Nitride Film, 500 µm, 20 nm
Silicon Nitride TEM Window Grids perform well under harsh conditions. They tolerate temperatures above 1000 deg C and support use in environmental TEMs where dynamic processes are observed at high temperatures. They provide an ideal balance of imaging resolution, chemical stability and mechanical strength. They can be vigorously plasma cleaned to remove organic contamination. The incorporate LPCVD, low-stress(~250MPa), non-stoichiometric silicon nitride to provide flat, insulating and hydrophobic surfaces.
Silicon frames are 100um thick. There is less than 0.5 nm variation in film thickness across an entire production log, not just a single window grid. Grids fit standard 3mm holders and most double tilt holders. They come in clear gel-boxes for simpler sample preparation. Recommended use: Suspensions and cryo-EM suspension.
Dimensions: 500 µm
Thickness: 20 nm

Electron Microscopy Sciences Lacey Carbon Film with Ultrathin Carbon 3 nm thick on 400 mesh Copper Grid
The continuous ultrathin carbon film on lacey carbon allows for the thinnest support film that still has adequate strength to withstand electron microscope specimen preparation. The less than 3nm thick film lies across a carbon lacey film supported by a mesh grid. The size of the holes in the lacey film differ widely from batch to batch but are generally in the range of ¼ µm to 5µm, which gives the equivalent support of at least 6000 mesh grid.
Specimen material lying over the covered holes can be imaged in the TEM with practically no interference from the carbon film supporting it. This product is ideal for looking at nanotubes, virus particles and other small particulate material.

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.

Electron Microscopy Sciences EDX-XEDS Calibration TEM Window Grid
Germanium is an ideal calibration standard for x-ray energy dispersive spectroscopy in electron microscopes since it is not typically found in TEM columns it cannot be mistaken for instrument components and their signal peaks. For TEM the Ge is suspended across two micron pores that are patterned on a grid of 20 nm thick silicon nitride. The single 500 x 500 micron window is compatible with high tilt angle tomography, since at 70 degrees of tilt, the thin and beveled 100 micron silicon frame allows you to use a ~50x50 micron region within the center of the window from any rotational orientation.
The specimen can be used for detector energy axis and energy resolution calibration, detector window transmission evaluation, detector solid angle measurements, electron optical instrument system peak measurements, and specimen holder penumbra measurements.
