UV Resistant Material Selection
Some plastics degrade rapidly under UV. Shorter wavelengths reduce deep penetration and help protect surrounding structures.
Suitable Materials
Quartz
PTFE
UV-grade silicone
Engineering Consideration
Controlled penetration wavelengths like 230nm reduce unintended exposure.

Conclusion
Material compatibility is critical for long-life sterilization systems.
