Diffusion Pump Oil

Diffusion pump oil is cheaper but equivalent to silicone based oil, very useful for industrial usage.

Added advantage over conventional diffusion pump oils :

• Colorless transparent oily liquid
• Excellent heat stability
• Very high boiling point
• Extremely low volatility
• Gives pressures down to 5X10-6 mm Hg (6X10-6 m bar)
• Very low toxicity
• Absolutely non-corrosive to most metals
• Equivalent to Silicon DP oil

Applications :
In diffusion pumps to achieve high vacuum replaces expensive Silicone Oil.
