NALGENE® 4108 Erlenmeyer Flasks with Screw Closure, polycarbonate; polypropylene closure

Use for preparation and storage of culture media and many culturing techniques. Far safer than glass flasks for use in shakers. Closures are linerless, non-contaminating. Flasks and closures are autoclavable, but polycarbonate shows some loss of mechanical strength after repeated autoclaving. Before autoclaving, set closure on top of the container without engaging the threads. Autoclavable/Transparent.
