Agilent IDP-35 and IDP-45 Dry Scroll Pumps

Significance of the topic

The Agilent IDP-35 and IDP-45 dry scroll pumps represent a cornerstone in modern vacuum technology, delivering oil-free, clean vacuum environments essential for sensitive analytical and industrial applications. Their ability to maintain low ultimate pressure, combined with variable speed control, addresses the growing demand for flexible, reliable, and low-maintenance vacuum sources in research laboratories, quality control, semiconductor fabrication, and cryogenics.

Objectives and overview of the product

This data sheet aims to present the key features, performance metrics, and application benefits of the IDP-35 and IDP-45 scroll pumps. It highlights their smart inverter-driven motor, hermetic design, universal voltage compatibility, and optional accessories such as integrated isolation valves and gauges, enabling users to optimize pumping speed, noise level, and system safety.

Methodology

The performance of these scroll pumps is evaluated according to international standards: ISO 21360-1/2 for pumping speed and ultimate pressure, PNEUROP 6602 for water vapor handling, EN 61326 and EN 61000 series for electromagnetic compatibility, and helium leak testing (<1 × 10⁻⁶ atm·cc/s). Noise and vibration measurements follow EN ISO 2151, ISO 4871, and ISO 11201 protocols.

Used Instrumentation

• Hermetic dry scroll module with airtight seal for zero oil contamination
• Inverter-driven motor enabling 1,200–1,980 rpm speed tuning (40–66 Hz input)
• Integrated isolation valve option for system protection against backflow and power loss
• Standard interfaces (RS-232, RS-485, RJ-45) compatible with Agilent A-PLUS software
• LED display with hour meter for real-time monitoring
• Mobile chassis with integrated wheels for laboratory portability

Main performance and discussion

The IDP-35 achieves a peak pumping speed of 583 L/min (35 m³/h) and the IDP-45 reaches 750 L/min (45 m³/h) at 60 Hz. Both models attain an ultimate pressure of 8 × 10⁻³ Torr (1.07 × 10⁻² mbar). Water vapor handling ranges from 13–110 g/h (IDP-35) and 21–250 g/h (IDP-45) via adjustable gas ballast. Noise levels remain below 60 dB(A) without ballast. Leak rates under helium are <1 × 10⁻⁶ atm·cc/s, ensuring high integrity in helium applications.

The inverter-driven design allows reduction of rotational speed to minimize noise and extend service life under partial-vacuum conditions. Universal voltage compatibility (100–240 VAC, 50/60 Hz) simplifies global deployment. Integrated thermal protection and automatic restart safeguard motor health.

Benefits and practical applications

• Oil-free operation eliminates hydrocarbon contamination in analytical instruments (e.g., mass spectrometers, electron microscopes)
• Low vibration and noise suit vibration-sensitive setups such as atomic force microscopy
• Variable speed control optimizes performance for process-specific requirements
• Compact, wheeled design enhances mobility across shared laboratory spaces
• Optional isolation valve protects vacuum systems during power interruptions or maintenance

Future trends and opportunities

Advances in digital integration and IoT connectivity will enable remote monitoring, predictive maintenance, and AI-driven performance optimization. Further developments in magnetic bearings and advanced materials may push ultimate pressures lower while improving energy efficiency. The integration of smart diagnostics and cloud-based analytics will transform vacuum systems into self-adaptive platforms for next-generation research and manufacturing.

Conclusion

The Agilent IDP-35 and IDP-45 dry scroll pumps offer a robust, oil-free solution with flexible speed control, universal power compatibility, and advanced safety features. Their high performance and low maintenance requirements make them ideal for a wide range of industrial and academic applications, from routine laboratory vacuum to specialized cryogenic processes.
