Identi-Plug fits 14mm-20mm openings, 1000/carton

Identi-Plugs® are for use with test tubes and flasks. They are reusable and leave no clinging fibers like cotton plugs. They provide a snug fit, yet permit free air flow. Plugs are ideal for use with Drosophila vials.

They spring back to original shape after repeated use. Identi-Plugs® can also be used as a cleaner for lab pipettes, tubes, vials, as well as industrial precision tubing. Inscriptions with Identi-Marker pens may be made for quick identification.
