Our range of specialised ribbed stoppers are designed to fit snugly and tightly into blood collection tubes.

The lip on the base of the stopped grips the wall of the tube providing a tight seal while preventing the stopper from popping out of the tube.

The stoppers are manufactured from low density polyethylene and are available in a variety of colours for 12mm and 16mm diameter tubes.

1,000 pieces per bag, 20,000 pieces per case.
