Volumetric Flask Bumper Guards

United Scientific Bumper Guards for Volumetric Flasks provide a simple way to add extra protection to valuable volumetric glassware. The flexible silicone design slips easily onto compatible flasks, helping cushion the neck and reduce impact if a flask is accidentally tipped over onto the benchtop.

Each bumper features a wide protective profile made from high-quality silicone, giving labs an easy-to-use safeguard for everyday handling, storage, and workflow movement. Color-coded sizing makes it quick to match the guard to the appropriate flask capacity.
