Very versatile. Particularly suitable for storing pipettes. Rugged. No more chipped ends as pipettes are cushioned by PP. The jar, but not the PE cap, can be autoclaved at 120°C for 20 minutes. Tight fitting cover protects pipettes during transportation and from dust etc. Welded flanged base gives excellent stability. Can be easily cut down to suit shorter length pipettes. It can also be used for soaking pipettes that need to be washed.
