Description
Product Code: PM 996
Size: 4IN X 125FT (10cmx38m)
Description: Parafilm M is a unique self-sealing, moldable and flexible film for numerous uses in the typical laboratory. It has unique permeability properties, impressive water vapor transport properties, and is resistant to many common reagents. With the use of the special dispenser, which is sized to take either the 50 mm or 100 mm wide rolls, one can conveniently cut off uniform sized strips or squares of 50.8 mm in length. The thickness of all Parafilm products is 127µm.
Features: This film is a semi-transparent, flexible, thermoplastic film that provides a waterproof barrier for covering laboratory vessels. It is gas permeable with low water permeability. Ideal for use in Microbiology and Cell Culture applications as it does not affect oxygen or carbon dioxide permeability. Nontoxic material is resistant to acids, alkalis, alcohols and organic solvents.
