Description

Apiezon T is a high-performance, high-vacuum grease widely recognized for its exceptional stability and low vapor pressure. This makes it a critical component in demanding applications where maintaining a clean, stable vacuum environment is paramount. It is an essential material for research laboratories, analytical instrument manufacturers, and industrial facilities operating high-vacuum systems. The product is supplied under the identifier CAS NO 9064-45-3.

Application

• Lubrication and sealing for high-vacuum systems, including rotary vanes, diffusion pumps, and valves.
• Sealing and lubrication for glassware joints and stopcocks in laboratory and chemical processing setups.
• General-purpose lubricant for instruments and equipment operating under low-pressure or inert atmospheres.
• Use in mass spectrometers, electron microscopes, and other sensitive analytical equipment requiring ultra-clean vacuum conditions.
• Lubrication for bearings and gears in cleanroom or controlled atmosphere environments.
• Sealing applications for optical and electrical feedthroughs in vacuum chambers.
