Stretchable Sealing Caps
Tug on the pull tabs to stretch these caps onto the tips of bottles, beakers, flasks, and cylinders, creating an airtight seal. They’re flexible for a snug fit. Made of silicone, these caps withstand chemicals in high temperature applications up to 350° F, though they will swell if exposed to a solvent for too long. You can label and write on them with markers.
