Parafilm M^® Laboratory Film

Parafilm M^® is a moisture-resistant thermoplastic used in research, clinical and industrial laboratories. This laboratory film can be utilized to prevent contamination, evaporation or spills. Parafilm M^® is self-sealing, flexible, odorless, semi-transparent and can stretch and mold to irregular shaped surfaces providing a reliable barrier. Available in an array of sizes, Parafilm M^® can be useful in electron microscopy droplet staining and thin-film grid coating. It can also provide a non-slip surface on trays and shelves for instruments or containers.

Roll Sizes & General Purposes
any size may be used for EM applications

Product No. Size Suggested Uses

807 10cm x 38.1 meters
4" wide x 125' long Saves time when medium sized sheet or strips are needed for larger beakers, tubes, trays, containers and culture media.

807-4 50.8cm x 15.2 meters
20" wide x 50' long Horticulture research as a membrane for insect feeding, tray and shelf liner for bottles and instruments and other laboratory EM and microscopy applications.

807-5 10cm x 76.2 meters
4" wide x 250' long Saves time when medium sized sheet or strips are needed for larger beakers, tubes, trays, containers and culture media.

807-6 5cm x 76.2 meters
2" wide x 250' long For smaller applications, 2" squares can be cut quickly with the dispenser and used for test tubes, flasks, and covering irregular surfaces. In horticultural research, Parafilm M is used to seal grafts and cut stems to prevent moisture loss.

Permeability Characteristics:

Oxygen (ASTM 1927-98): 150 cc/m² d at 23°C and 50 RH

Carbon Dioxide (Modulated IR Method): 1200 cc/m² d at 23°C and 0% RH

Water Vapor (ASTM F1249-01): Flat: 1 g/m² d at 38°C and 90% RH Creased: same as flat

Note: Because of low water permeability and the insensitivity of this material to moisture vapor, it is unlikely that differences in relative humidity (RH) will make a difference in the oxygen permeability

Effects of Common Reagents:

Hydrochloric acid conc. (12N) dil. (5N) - no apparent effect in 24 hours

Sulfuric acid conc. (36N) dil. (5N) - no apparent effect in 24 hours

Nitric acid conc. (16N) dil. (5N) - no apparent effect in 24 hours

Sodium hydroxide conc. (22%) - no apparent effect in 24 hours

Ammonium hydroxide conc. (28% NH3) - no apparent effect in 24 hours

Potassium permanganate: 5%: no apparent effect except permanent dark brown coloration in 18 hours 0.1%: same as 5% but slightly less color Iodine solution 0.1N: no effect except brown staining in 18 hours

Salt (NACL) solution 20%: no apparent effect in 24 hours

Ethyl Alcohol 95%: no apparent effect except some face whitening in 24 hours

Isopropyl alcohol 99%: no apparent effect in 24 hours

Not recommended for use with chlorinated, non-polar aliphatic and aromatic solvents

Film becomes soft and sticky at about 130°F to 150°F (54°C to 66°C)
