Popular applications for SiMPore’s TEM grids include:


cryo-em icon

SiMPore’s Cryo-TEM grids include Silicon Nitride alone or with unique carbon coatings to provide superior bridging and maximum observable specimen sites of organic and biologic solutions and suspensions.

Hi-res Imaging


SiMPore offers the thinnest Silicon and Silicon Nitride TEM windows on the market enabling atomic-level resolution. They’re also plasma cleanable for easy removal of organic contaminants.

Sample Deposition


SiMPore TEM Grids can act as a robust substrate on which to deposit materials or grow nanoparticles or nanowires.

TEM Grid Options

SiMPore’s silicon nitride, silicon dioxide, and pure silicon TEM Grids enable researchers to characterize their samples and meet a variety of application-specific research needs. 

silicon nitride

Silicon Nitride

Ideal for temperatures > 1000°C

Silicon nitride grids are well-suited for use in environmental TEMs where dynamic processes are observed at high temperatures.

Flat and uniform surface

Silicon nitride grids incorporate LPCVD, low-stress (~250MPa), non-stoichiometric silicon nitride which provides uniformly flat, insulating, and hydrophobic surfaces.

Made for stable imaging

Nanoporous and microporous silicon nitride grids support stable suspension of nanoscale materials for imaging without a background.

pure silicon

Pure Silicon

Increases stability

Pure silicon grids offer greater stability at high beam currents and at moderately high annealing temperatures (up to 600°C).

Enables alternative for elemental analysis

Pure silicon grids enable elemental analyses by EDAX and EELS of samples containing nitrogen and/or carbon due to their composition and their minimal background signal.

Reduces chromatic blur

Compared to carbon grids, pure silicon grids have half the chromatic blur.

silicon dioxide

Silicon Dioxide

Created with stoichiometric silicon dioxide

Silicon dioxide grids offer the ability to analyze for nitrogen by elemental analyses such as EDAX and EELS.

Capable of withstanding harsh conditions

Silicon dioxide is able to handle harsh deposition and chemical conditions by providing an ideal balance of imaging resolution and mechanical strength.



Greater contrast

Research findings indicate that viral particles prepared on Cryo-SiN exhibit greater contrast in comparison to those prepared on holey carbon films under the same conditions.

Less imaging

It is significantly easier to calculate 3D reconstructions of viral particles when they’re prepared on Cryo-SiN, as they require only a fraction of the images required for samples prepared on holey carbon films.
