What Is Krytox™ GPL 215 Lubricating Grease?

Krytox™ GPL 215 is a premium lubricating grease from the Chemours Krytox GPL series, formulated with a perfluoropolyether (PFPE) base oil and a polytetrafluoroethylene (PTFE) thickener. The combination of PFPE and PTFE delivers outstanding chemical inertness, making the grease compatible with a wide range of aggressive chemicals, oxidizers, and solvents commonly encountered in laboratory and industrial settings.

The product is supplied under SKU K1547832 by Aladdin Scientific. As part of the established Krytox GPL line, GPL 215 occupies the mid-to-high consistency range, providing a balance between pumpability and load-bearing capability suitable for precision equipment lubrication.

Key Properties and Performance Characteristics

Krytox™ GPL 215 exhibits several performance attributes that distinguish it from conventional hydrocarbon or silicone-based greases:

• Chemical Inertness: The PFPE backbone is resistant to virtually all laboratory chemicals, acids, bases, and oxidizing agents, preventing grease degradation in reactive environments.
• Non-Flammability: GPL 215 does not ignite under standard conditions, an important safety feature for use near flammable gases or in oxygen-rich atmospheres.
• Thermal Stability: The grease maintains lubrication performance across a broad temperature range, from cryogenic conditions up to elevated operating temperatures typical of research instrumentation.
• Vapor Pressure: The low vapor pressure of PFPE base oils makes GPL 215 suitable for high-vacuum and ultra-high-vacuum applications.
• Non-Toxic and Environmentally Stable: PFPE-based greases are generally considered non-toxic and do not react with biological samples, making them appropriate for use in life science instrumentation.

Note: Specific numerical values for viscosity, operating temperature range, and NLGI grade are not confirmed in the source material and have been flagged for review.

Typical Laboratory and Industrial Applications

Krytox™ GPL 215 is widely used across research and industrial settings where conventional lubricants would fail or cause contamination:

• Vacuum Systems: Ideal for lubricating stopcocks, O-rings, and fittings in high-vacuum lines due to its low vapor pressure and chemical inertness.
• Valves and Regulators: Suitable for gas and liquid handling valves, including those used with corrosive or oxidizing gases such as chlorine, fluorine, and strong acids.
• Precision Instruments: Used to lubricate bearings, slides, and moving parts in analytical instruments where hydrocarbon contamination must be avoided.
• Cryogenic Equipment: Retains lubricating properties at low temperatures, making it useful in cryogenic storage and handling systems.
• Semiconductor and Cleanroom Environments: Its non-outgassing and particle-free nature supports use in sensitive fabrication environments.

Handling, Storage, and Safety Guidance

Although Krytox™ GPL 215 is chemically stable and non-flammable, standard laboratory safety practices should be observed:

• Storage: Store in a cool, dry location away from direct sunlight. Keep containers tightly closed when not in use to prevent contamination.
• Handling: Use clean, dedicated applicators to avoid introducing contaminants into the grease. Avoid mixing with incompatible materials such as hydrocarbon oils or silicone greases, which may compromise performance.
• Personal Protective Equipment (PPE): Gloves and eye protection are recommended as a precaution during application, consistent with standard laboratory chemical handling protocols.
• Disposal: Dispose of used grease in accordance with local regulations. PFPE materials are generally chemically stable and do not readily biodegrade; consult local waste disposal guidelines.
• Safety Data Sheet (SDS): Always consult the current SDS provided with the product for detailed hazard and first-aid information before use.

Note: Specific SDS data and hazard classifications have not been confirmed from the source material and are flagged for review.

Frequently asked questions

What type of base oil is used in Krytox™ GPL 215 grease?

Krytox™ GPL 215 uses a perfluoropolyether (PFPE) base oil thickened with polytetrafluoroethylene (PTFE). This combination provides excellent chemical resistance, thermal stability, and non-flammability compared to conventional hydrocarbon or silicone-based greases.

Is Krytox™ GPL 215 compatible with oxygen and oxidizing environments?

Yes, PFPE-based greases such as Krytox™ GPL 215 are generally considered compatible with oxygen and oxidizing agents because the fully fluorinated polymer backbone does not react with oxidizers under normal operating conditions. This makes GPL 215 suitable for use in oxygen service valves and fittings. Always verify compatibility for your specific application conditions and consult the current SDS.

Can Krytox™ GPL 215 be used in vacuum systems?

Yes, Krytox™ GPL 215 is well suited for vacuum applications. Its PFPE base oil has a low vapor pressure, which minimizes outgassing and contamination of vacuum lines. It is commonly used to lubricate O-rings, stopcocks, and fittings in high-vacuum laboratory setups.

What is the SKU for Krytox™ GPL 215 at Aladdin Scientific?

The SKU for Krytox™ GPL 215 lubricating grease at Aladdin Scientific is K1547832. You can search this SKU directly on the Aladdin Scientific website to view pricing, pack sizes, and availability.

How should Krytox™ GPL 215 grease be stored?

Krytox™ GPL 215 should be stored in a cool, dry location away from direct sunlight and heat sources. Containers should be kept tightly sealed when not in use to prevent moisture ingress and contamination. Avoid mixing with other lubricant types such as hydrocarbon or silicone greases.
