The Agilent DS102 (formerly Varian DS102) is a dual-stage, oil-sealed rotary vane vacuum pump designed for efficient and reliable vacuum generation in various laboratory and industrial applications.

Key Features:

• Pumping Speed: Delivers a pumping speed of 5.0 m³/hr at 50 Hz (approximately 3.5 CFM at 60 Hz), ensuring effective evacuation of vacuum systems.
• Ultimate Pressure: Achieves a base pressure of less than 2 × 10⁻³ mbar, suitable for applications requiring deep vacuum levels.
• Motor Specifications: Equipped with a universal-voltage single-phase electric motor (100–120/200–230 VAC, 50/60 Hz) with an integral power switch, offering flexibility in various electrical environments.
• Inlet Isolation Valve: Features an integrated inlet isolation valve that automatically isolates the vacuum system when the pump stops, preventing pressure rise and oil backflow.
• Gas Ballast Valve: Includes a manual gas ballast valve that allows the pump to handle water vapor by introducing a controlled amount of atmospheric air into the pump during operation.
• Anti-Suckback Device: Incorporates a special anti-suckback mechanism that isolates the vacuum system upon pump shutdown, preventing pressure rise or oil flow back into the vacuum system.

Applications:

The DS102 is widely used in laboratory settings, including:

• Mass spectrometry
• Chromatography
• Surface analysis
• Thin film deposition
• Electron microscopy
