Tiered Plug Stopper Closures, Polyethylene, Globe Scientific
Test/Sample Tube Closures
Polyethylene flanged plug caps provide exceptional leak-resistance in test tubes, centrifuge tubes, and round cuvettes
Closures fit 12mm tubes, and are available in a variety of colors to simplify identification and selection.
They feature two flexible flanges that press firmly against the inside of the tube wall, thereby providing better leak-resistance than standard plug caps.
