Description
Laboratory film (parafilm) size: 2″ X 250′ Quickly, effectively seals labware Waterproof, moisture-proof film prevents sample evaporation, contamination; protects anhydrous materials Can be folded repeatedly and twisted around sharp surface without rupturing Increases approximately 200% when stretched lengthwise at 21°C (70°F) Parafilm tape is a semi-transparent, flexible, self-adhesive plastic film commonly used in laboratories to seal containers like petri dishes, tubes, and flasks, providing a moisture barrier while still allowing gas exchange; it is essentially a stretchy, moldable plastic wrap that sticks to itself and is often used for applications where a tight, yet breathable seal is needed.
