These 45mL (1.5oz.) Corning Snap-Seal polypropylene containers are designed for a wide variety of applications and provide a reliable leak-tight seal when closed properly.
The Snap-Seal locking device keeps the cap closed and secure.
The specially-designed hinged cap stays in place in use, reducing the chance of sample contamination.
The containers are graduated in both milliliters and ounces, and the cap has a rough surface for marking.
