Parafilm M - 4 Inch * 125 Ft Roll

Parafilm M is a non-sterile, semi-transparent thermoplastic laboratory sealing film. This 4 inch x 125 ft roll forms a flexible, self-sealing moisture barrier around laboratory vessels and irregular surfaces.

• Use a suitable piece of film to cover or seal a laboratory vessel.
• Stretch the film around the vessel or surface to form a close seal.
• Ensure the film clings around the surface before use.

• Semi-transparent, flexible thermoplastic film with a self-sealing surface.
• Stretches up to 200% and clings around irregular shapes and surfaces.
• Resistant for up to 48 hours against many polar substances, including saline solutions, inorganic acids and alkaline solutions.
• Latex-free and odour-free.
• Non-sterile material.

• Do not use with chlorinated, non-polar aliphatic or aromatic solvents.
• The film becomes soft and sticky at about 54 to 66 °C.
• This is a non-sterile laboratory sealing film.

• Seal beakers, flasks, petri dishes and multi-well plates during laboratory work.
• Cover laboratory vessels with irregular shapes or surfaces.
• Use in research applications where a moisture barrier is needed.
• Seal suitable glassware to help limit evaporation and volume loss.

• A tight seal may help limit moisture loss, evaporation and volume loss.
• The flexible material may help protect samples from contamination.
• Its self-sealing fit may help it cling to irregular surfaces and glassware.
• Stretchability may help create a secure fit without tearing.
