Product Description
When precision matters in your lab, the right lubricant can make all the difference. Silicone Grease, High Vacuum LR from Avantor is engineered for demanding applications where airtight seals and smooth operation are non-negotiable. Whether you’re working with vacuum pumps, glass joints, or delicate scientific instruments, this LR-grade grease delivers reliability without compromising performance.
Unlike standard lubricants, this high vacuum silicone grease resists breakdown under extreme temperatures and pressure, making it a staple in research labs, educational institutions, and industrial settings. Its inert nature ensures compatibility with most materials, while the LR grade guarantees minimal impurities for sensitive experiments.
Students and researchers often struggle with leaky vacuum setups or stiff O-rings. A thin layer of this grease solves both issues instantly, extending the life of your equipment and reducing downtime. Educators appreciate its ease of use when demonstrating vacuum principles in classrooms.

Why This Grease Stands Out
Not all silicone greases are created equal. This Avantor product is formulated specifically for high-vacuum environments, where even minor contamination can skew results. The LR grade certification means it meets strict purity standards, so you can trust it for critical applications like mass spectrometry or freeze-drying.
Its versatility extends beyond vacuums. Use it to lubricate stopcocks, ground glass joints, or rubber seals in your lab apparatus. The grease remains stable from -40°C to 200°C, ensuring consistent performance whether you’re working in cold storage or near heat sources.
For students setting up their first chemistry experiments, this grease is a game-changer. No more struggling with jammed glassware or air leaks during distillation. A small investment in quality lubrication saves hours of frustration.
Practical Applications in Your Lab
Vacuum Systems: Creates reliable seals in Schlenk lines, rotary evaporators, and vacuum desiccators.
Glassware Assembly: Eases the connection of ground glass joints in distillation setups.
O-Ring Maintenance: Prolongs the life of rubber seals in pumps and valves.
Educational Demos: Ideal for physics and chemistry experiments requiring airtight conditions.

Safety and Handling
While silicone grease is generally non-toxic, always follow standard lab safety protocols. Avoid contact with eyes and skin. Store in a cool, dry place away from direct sunlight. For high-risk applications, refer to the SDS provided with your order.
FAQs
What makes high vacuum silicone grease different from regular grease?
High vacuum grease is formulated to have extremely low vapor pressure, preventing outgassing that could contaminate vacuum systems. Regular greases may degrade under vacuum conditions.
Can I use this grease on plastic components?
Yes, this silicone grease is compatible with most plastics, rubber, and glass. However, always test on a small area first for critical applications.
How much grease should I apply to O-rings?
A thin, even layer is sufficient. Excess grease can attract dust and debris, potentially compromising the seal.
Is this grease suitable for food or medical applications?
No, this LR grade grease is intended for laboratory use only. For food or medical applications, use USP-grade silicone grease.
How long does a 50g tube typically last?
For occasional lab use, a 50g tube can last several months to a year. Frequent users may need to reorder every few months.
