Coolglow

Cryo-TEM Grid Hydrophilic Treatment

With the increasing demand for imaging applications, it is more important than ever to use clean and consistently high-quality TEM grids. Coolglow is a compact and user-friendly glow discharger that generates a vacuum pressure of <50Pa using a high-performance mechanical pump. It then ionizes the air using an RF power supply, causing a transition of the grid surface from hydrophobic to hydrophilic. This allows for more uniform dispersion of polar suspensions on the carbon film. The RF power supply is efficient, producing a plasma that is gentler (<15eV) and has good reproducibility, resulting in reliable and repeatable results.

Plasma Cleaning of Sample Surface

Coolglow also offers plasma cleaning of the sample surface to eliminate carbon accumulation during the imaging process.
