When it comes to diffusion pumps, the type of oil used is crucial for maintaining high vacuum levels.
Silicone oil is the most commonly used oil in diffusion pumps.
This choice is primarily due to its high vapor pressure and stability.
Silicone oil is known for its durability and minimal degradation over long periods of operation.
4 Key Reasons Why Silicone Oil is Preferred in Diffusion Pumps
1. High Vapor Pressure and Stability
Silicone oil has a high vapor pressure, which is essential for maintaining high vacuum levels in the pump.
Its stability ensures that the oil remains effective over time.
2. Temperature Resistance
Silicone oil can withstand high temperatures without breaking down.
This is crucial for the operation of diffusion pumps, where the oil is heated to generate vapor.
The vapor moves rapidly downward to capture air molecules and remove them from the vacuum chamber.
3. Minimal Contamination Risk
The use of silicone oil minimizes the risk of contamination in the vacuum chamber.
Although some oil molecules may remain in the chamber, silicone oil is less likely to cause significant issues compared to other types of oils.
4. Safety Features
Silicone oil is relatively safe from a toxicity and flammability standpoint.
This is important for operational safety.
