ELMO – Glow Discharge System for EM grids

Your TEM grids ready within seconds.

Hydrophilic or hydrophobic, Negative or Positive charge

A Glow Discharge treatment with a specific gas atmosphere will modify the surface properties of TEM support films or grids in order to optimize the adsorption of the solutions to spread.

TEM carbon support films have a hydrophobic tendency. A glow discharge treatment with air makes the carbon film surface negatively charged and hydrophilic which allows an adsorption of aqueous solutions.

Thanks to a glow discharge treatment with amylamine the hydrophobic tendency of the carbon film is kept and the surface is charged positively allowing an adsorption of molecules like nucleic acids.
