The GloQube® is a compact, easy-to-use glow discharge system primarily used for the hydrophilisation (wetting) of TEM support films and grids. Other applications include the modification of surfaces of polymers and plastics. The GloQube features an automated and quick cycle with fully selectable parameters. The GloQube features a single drawer with two independent vacuum chambers: a clean chamber for applications requiring hydrophobic/hydrophilic conversion and a vapour chamber designed for hydrophilic/hydrophobic (negative or positive) conversions. The GloQube-S has a single clean chamber.
