Parafilm M® All-Purpose Laboratory Film

A versatile, moisture-resistant, thermoplastic flexible plastic for a wide variety of clinical and industrial applications, Parafilm M® film has been used with confidence for years in scientific research and laboratory settings.

It is a proven fast, economical covering or stopper for test tubes, beakers, vials, petri dishes, flasks and various instruments and objects with irregular surfaces.

It is an ideal shelf or tray liner to prevent slipping of bottles or instruments. It is odorless and semi-transparent.

In laboratories, Parafilm M® sheet is a thermoplastic, self-sealing film that holds moisture loss to a minimum and offers excellent barrier protection to the contents of tubes, flasks, culture tubes, etc.

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): 1 g/m² d at 38°C and 90% RH

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
  • Sulphuric 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 chorinated, non-polar aliphatic and aromatic solvents

Film becomes soft and sticky at about 130°F to 150°F (68°C)
