Parafilm M Lab Sealing Film

A semi-transparent, flexible, thermoplastic with paper backing film that provides a waterproof barrier for covering laboratory vessels, ideal for use in microbiology and cell culture applications as it does not affect oxygen or carbon dioxide permeability.

Features and Benefits:

• Pliable, thermoplastic sheet material, substantially colorless
• Waterproof and moisture proof film, prevents sample evaporation/contamination
• Stretches approximately more than 350% of its original length, becomes more flexible and softer as temperature increases.
• Self-sealing, allowing to cling around irregular shapes and surfaces, ideal for protecting the contents of test tubes, flasks, beakers, petri dishes, stoppers, lids and caps.
• Can be folded repeatedly and tested around sharp surface without rupturing
• Resistant to most acids and alcohols yet gas permeable
• Ideal for wrapping beakers and flasks
• Resistant against many polar substances for up to 48 hours.
• Dimension: 4” x 125ft/r
