Parafilm M Verschlussfolie (50 cm x 15 m)

Parafilm® M is highly insensitive to water, moisture loss and moisture absorption, yet is permeable to
oxygen and carbon dioxide. Parafilm® M stretches more than 350% of its original length and is selfsealing, allowing it to cling around irregular shapes and surfaces. These unique properties make it
ideal for protecting the contents of test tubes, flasks, beakers, and Petri dishes as well as an
overwrap to further secure stoppers, lids and caps.

Effects of Common Reagents
Parafilm® M is resistant against many polar substances for up to 48 hours. After this period, some
brittleness may occur. It is not recommended for use with chlorinated or non-polar aliphatic or
aromatic solvents.
