Performance features:

• high flow rates even at vacuum levels approaching ultimate vacuum
• high water vapor tolerance due to efficient gas ballast;
• very good ultimate vacuum even with gas ballast
• vacuum-tight at switch-off; external anti-suckback valve not needed
• large oil volume: Long intervals between oil changes
• ease of maintenance due to telescopic design

Applications

Typical applications are lyophilization, fine vacuum distillation and evacuation of small volumes, e.g., for utilization of μ-focus x-ray tubes or filling with pure gases. The pumping unit PC 3 is the perfect choice for applications requiring special protection of pump and environment. Designed for the use in chemical laboratories, the cold trap helps the pumps handle large volumes of condensable vapors. The cold trap is metalized for extended coolant life and is protected against implosion.
