Glow Discharge Methods supported:
| Surface Condition | Charge | Atmosphere |
|---|---|---|
| Hydrophilic | Negative | Air |
| Hydrophilic | Positive | Air (with subsequent magnesium Acetate treatment) |
| Hydrophobic | Positive | Alkylamine |
| Hydrophobic | Negative | Methanol |
Efficient glow discharge performance for the PELCO easiGlow™ with optimum pressure at given distance from sample to glow discharge head.
For those labs which need both hydrophilic and hydrophobic surface treatments on a regular base, a dual glow discharge system is available to avoid cross contamination of the glow discharge chambers. Hydrophobic surfaces are preferable when organic solvents are used.
Since the optimised vacuum level for glow discharge procedures is in the range of 0.45 to 1.1 mbar, we offer the affordable GD7 dual stage rotary vacuum pump designed for this pressure range.
Advantages of the PELCO easiGlow™ system:
- Precise and easy vacuum setting
- Short cycle times
- Consistent results
- Auto, programmed and manual mode
- Intuitive touch screen for display and operation
- Supports hydrophilic/hydrophobic and negative/positive modes
- Affordable, compact, standalone system
- L‐Gasket protects glass jar at base
