Humulin® R U-500 comes in a 20mL vial that's larger than a standard insulin vial—and standard-sized protectors don't fit it. This Clear 2-Pack from Vial Safe® is specifically designed for the 20mL Humulin R U-500 vial, providing a precise fit and full drop protection. The medical-grade silicone absorbs impact so the glass bounces instead of shattering.

Fits 20mL Humulin® R U-500 vials only.

Clear silicone for 360° label visibility. Patented open-top design for draw-through needle access. If you're on concentrated insulin, a broken vial is especially costly—this protector is inexpensive insurance against that.

Made in the USA from BPA-free, latex-free, hypoallergenic silicone. Reusable, easy to clean, and built to outlast dozens of vials. HSA/FSA eligible.
