EMS GRIDS & TEM SUPPORT FILMS CATALOG EDITION V TEM WINDOW GRIDS


zzz Cryo-SiN An ideal substrate for cryo-microscopy.


z Avoid substrate degradation seen with carbon grids.


z Plasma cleanable to reduce contaminants.


z Our proprietary carbon coating may also improve charge dissipation leading to a reduction in beam induced movement.


z Large 500 µm windows provide ~50 x 50 µm viewing from any orientation at 70 degrees of tilt for tomography.


“Our initial findings indicate that viral particles prepared on Cryo-SiN, exhibited greater contrast in comparison to those prepared on holey carbon films under the same conditions. As a result, we were able to calculate 3D reconstructions of viral particles prepared on Cryo-SiN using a fraction of the images required for samples prepared on holey carbon films.”

Nanoporous, Microporous and Microslit.


Our Porous Membrane Chips are available in a range of membrane types and pore sizes and shapes to suit a variety of applications.


Nanoporous Silicon Nitride — Proprietary membranes that are 100 nm thick that have average 50 nm diameter pores and 20% porosity, with one, two or four membrane/chip formats, with high-resolution imaging and separation properties.


4-slot Membrane Chip


Microporous Silicon Nitride — Robust membranes that are 400 nm thick and have either 0.5, 3 or 8 µm diameter pores and high (20%) porosity, suitable for more demanding applications.


Microslit Silicon Nitride — Novel rectangular prism-shaped pores in robust 400 nm thick silicon nitride membranes with 10% porosity, suitable for separation applications.


G-FLAT™ Silicon Oxide — Proprietary and optically transparent membranes for high-resolution imaging applications, available with either 0.5, 3, 5 or 8 µm diameter pores and low (5%) or high (20%) porosity.


Plasma Compatible — All of our Porous Membrane Chips can be treated with oxygen or oxygen-argon plasma for surface activation and/or removal of any organic contamination.


Device Integration — Our Porous Membrane Chips can be easily integrated into microfluidic-type applications where suspension of materials of interest across a permeable and transparent membrane is desired.


Ultrathin Membranes — Flat, uniformly deposited films and 100 nm to 400 nm thick suspended membranes provide consistent backgrounds with low field-to-field variability and high optical transparency.
