Description

Apiezon N is a high-purity, high-molecular-weight hydrocarbon grease widely recognized for its exceptional chemical inertness and thermal stability. This product is essential for creating reliable, non-reactive seals and lubricants in demanding high-vacuum and analytical applications. It is a critical material for industries and research facilities requiring contamination-free performance in sensitive environments, such as vacuum systems, spectroscopy, and specialized laboratory equipment.

Application

• High-vacuum sealing and lubrication for glassware, stopcocks, and O-rings.
• Sealant and lubricant for infrared (IR) and other spectroscopy sample cells.
• General-purpose, inert grease for laboratory glassware joints and apparatus.
• Lubricant for mechanical components operating under vacuum conditions.
• Sealing agent for connections in gas chromatography and mass spectrometry systems.
• Protective coating or seal for optical and electrical components in controlled environments.
