Parafilm® M Laboratory Film
Parafilm® M is a flexible, stretchable, moldable, moisture resistant, thermoplastic, self-sealing, wrapping film for laboratory use. It is colorless (semi-transparent), odorless, tasteless, approximately 0.005" thick, and resistant to alcohol and some acids and alkalies. It acts as a barrier to moisture loss as it is highly insensitive to water vapor, yet is permeable to gases making it suitable for culture media experiments. Parafilm M is ideal for protecting contents of beakers, broth tubes, culture flasks, culture tubes, petri-dishes, and containers.

 Store: 45°F to 90° (7°C to 32°C).
