Description

Apiezon(R) K, Package With 100 Ml CAS NO 66814-19-5 is a high-purity, high-vacuum grease widely recognized for its exceptional stability and low vapor pressure. This product is essential for creating reliable, long-lasting seals in demanding high-vacuum and ultra-high-vacuum systems. It is a critical material for research laboratories, analytical instrument manufacturers, and industrial facilities requiring contamination-free environments. The 100 mL package size is ideal for routine maintenance and operational use.

Application

• Sealing and lubrication of stopcocks, joints, and valves in high-vacuum systems and glassware.
• Lubrication for O-rings, ground glass joints, and rotary vanes in vacuum pumps and analytical instruments.
• General-purpose, non-reactive grease for laboratory equipment where hydrocarbon-based lubricants are suitable.
• Use in mass spectrometers, electron microscopes, and other sensitive analytical equipment requiring minimal outgassing.
• Sealing applications in systems handling dry gases and certain inert atmospheres.
• Light-duty lubrication for precision mechanical assemblies in controlled environments.

Quality Control

Our Apiezon K is manufactured under strict controls to ensure batch-to-batch consistency and performance. Key parameters such as vapor pressure, consistency, and thermal stability are rigorously tested. While this is a well-established specialty product, Certificates of Analysis (COA) detailing lot-specific properties are 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 at room temperature (15-25°C). Keep away from strong oxidizing agents and heat sources. Ensure the container lid is securely closed after each use to prevent contamination and maintain product integrity.
