Foam plugs for all size test tubes and laboratory flasks.

Identi-PlugsĀ® 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-PlugsĀ® 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.
