MiniQ GD Glow Discharge System
The Quorum MiniQ GD is a compact, single-chamber glow discharge system designed to modify the surface wettability of TEM grids and other substrates. By altering surfaces from hydrophobic to hydrophilic, it allows liquid solutions to spread evenly, improving particle adhesion and macromolecule imaging.
Featuring a standard 50mm sample stage and fully automated operation, the MiniQ GD offers pre-set profiles for positive and negative DC glow discharge with selectable plasma currents (10mA, 20mA, 30mA). It is the ideal benchtop plasma cleaner for busy EM laboratories requiring quick and reliable sample surface activation.

Applications: TEM & Surface Modification
-
TEM Grid Preparation Modifies carbon-coated TEM grids from hydrophobic to hydrophilic, essential for negative staining and cryo-EM.
-
Improved Particle Spreading Ensures liquid-applied samples spread evenly across the grid rather than beading up, improving macromolecule imaging.
-
Surface Cleaning Soft plasma cleaning removes hydrocarbon contamination from SEM stubs and other delicate substrates.
-
Dual Polarity Treatment Choose between positive and negative glow discharge depending on the surface charge requirements of your sample.
-
Surface Activation Activates surfaces for better adhesion of biological samples, polymers, and liquid suspensions.
MiniQ GD Frequently Asked Questions

The MiniQ GD requires a rotary pump (e.g., Pfeiffer Duo 6). We can supply the system as a standalone unit or a complete package including the pump and oil mist filter.
Yes, the 50mm stage can accommodate SEM stubs for cleaning or surface modification, making it a versatile tool for any microscopy lab.
Glow discharge treatment makes the carbon support film hydrophilic. This allows aqueous samples to spread thinly and evenly, which is critical for high-resolution imaging and reducing background noise.
The MiniQ GD is a compact, benchtop unit with a small footprint (225x420mm). It offers fully automated operation with practically zero user intervention required, unlike older manual systems.
