For large ampules. Amber UVLI™ covers provide a convenient, cost-effective, and disposable solution for protecting light-sensitive medications during transportation and administration. The semi-transparency of our Amber UVLI™ makes it easy to read labels and levels underneath without lifting the cover. Our covers and bags exceed the United States Pharmacopoeia Standard blocking over 90% of harmful UV light between 290nm and 450nm, so you can protect with confidence. Regular UVLI™ covers are fully sealed on three sides.
