Description

Leybold Vacuum Pump Oil is a high-performance, fully synthetic lubricant specifically engineered for demanding vacuum applications. Its formulation ensures exceptional vapor pressure, thermal stability, and chemical resistance, which are critical for maintaining deep vacuum levels and protecting pump components. This oil is essential for industries requiring reliable and efficient vacuum generation, such as analytical instrumentation, semiconductor manufacturing, and research laboratories. Consistent quality and performance are guaranteed to meet the rigorous demands of modern vacuum technology.

Application

• Lubrication and sealing for rotary vane and piston vacuum pumps in laboratory and industrial settings.
• Use in high-vacuum systems for analytical instruments like mass spectrometers, electron microscopes, and freeze dryers.
• Critical fluid for vacuum furnaces, coating systems, and optical thin-film deposition processes.
• Performance fluid in semiconductor fabrication equipment, including etching and chemical vapor deposition (CVD) tools.
• General-purpose lubricant for mechanical pumps handling strong acid/organic solvent vapors and other aggressive media.
• Maintenance of vacuum integrity in pharmaceutical production and packaging lines.
• Use in refrigeration and air-conditioning compressor systems requiring high-stability lubricants.

Quality Control

Our Leybold Vacuum Pump Oil is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including viscosity index, flash point, pour point, and vapor pressure to meet or exceed industry standards for high-grade vacuum oils. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment and is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent contamination and absorption of moisture.
