Medical Technology Lubricants Engineered for Reliability Under Radiation
Radiation-resistant PPE fluids, optical fluids, lubricants and greases, vacuum fluids, and connector lubricants for medical equipment and instruments.
SantoLubes supports medical technology across imaging and radiation therapy equipment, radiation sterilization systems, medical optical devices, diagnostic and laboratory instruments, and the electronics that run them. In these systems, a lubricant that thickens under radiation or evaporates onto an optic means downtime, recalibration, and a service call. Our polyphenyl ether (PPE) chemistry holds its structure under ionizing radiation and heat, and its low volatility keeps it from drifting onto nearby components.
Our medical technology portfolio includes SantoRad™ radiation-resistant fluids, SantoLight™ optical fluids, SantoLubes® PPE base fluids for specialty lubricants and greases, SantoVac® vacuum fluids for analytical instruments, and ACCL® connector lubricants.

These products are intended for medical equipment and instruments. Device manufacturers are responsible for regulatory qualification, including biocompatibility for any patient-contact use.
Why Radiation Resistance Matters in Medical Equipment
Imaging systems, radiation therapy equipment, and sterilization lines expose their own components to ionizing radiation every day. Conventional hydrocarbon lubricants break down under that exposure. They thicken, form gels, and lose film strength, and the cumulative dose builds with every shift.
PPE fluids are built on an aromatic ring structure that holds together under gamma rays, x-rays, and charged particles. SantoRad™ fluids resist radiation levels as high as 10¹¹ ergs/gram, so lubricated components keep moving freely between scheduled service visits.

FAQ
Answers to common questions about SantoLubes technologies in medical technology applications.
What lubricants and fluids are used in medical technology equipment?
Medical equipment uses radiation-resistant lubricants for components near imaging and therapy sources, optical fluids for imaging assemblies, low-volatility lubricants and greases for precision mechanisms, vacuum fluids for laboratory instruments, and connector lubricants for device electronics. SantoLubes covers these needs with SantoRad™, SantoLight™, SantoLubes® PPE base fluids, SantoVac®, and ACCL® technologies.
Why do imaging and radiation therapy systems need radiation-resistant lubricants?
Ionizing radiation breaks down conventional hydrocarbon lubricants. They thicken, form gels, and stop protecting the parts they were applied to. SantoRad™ PPE fluids resist radiation up to 10¹¹ ergs/gram and keep their viscosity and film strength, which helps equipment run longer between service visits.
Can SantoLubes fluids be used in radiation sterilization equipment?
Yes. Radiation processing and sterilization is one of the listed applications for SantoRad™ fluids. Their radiation and thermal stability suit conveyors, drives, and mechanisms that operate inside gamma and e-beam processing zones. Our team can review your equipment and recommend the right grade.
Where does SantoLight™ fit in medical devices?
SantoLight™ SL-5262 is an optical-grade PPE fluid for medical and nuclear optical devices. Its high refractive index supports index matching between optical components, and it keeps its clarity under ionizing radiation, where conventional optical fluids can yellow or cloud.
Are SantoLubes products approved for patient contact?
The products on this page are intended for medical equipment and instruments, not for direct patient contact or implantable use. Device manufacturers are responsible for regulatory qualification, including biocompatibility testing where it applies. Contact SantoLubes for the technical and safety documentation you need for your qualification process.
Can SantoLubes support custom medical technology application reviews?
Yes. Our team can evaluate radiation dose, temperature, volatility, optical requirements, materials compatibility, and connector reliability to recommend or help develop the right fluid. Custom formulation and private-label work is available through our affiliate, SantoTolling.
