Moisture-proof film molds to surfaceParafilm® M is a semi-transparent, flexible, thermoplastic film with two-way stretch.Non-toxic and free from plasticizers, primarily composed of polyolefins and paraffin waxes offering good resistance against acids, alkalis and some organic solvents—use not recommended with acetone, diethyl ether or tetrachlorideProtect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn’t release from glassware, despite off-gassingReduce the risk of tampered data with a covering that is odorless, colorless and semi-transparentPrevents moisture and volume loss due to material composition and tight sealFlexible and self-sealing material allows it to cling around irregular shapes and surfacesStretches more than 200% of original lengthResistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutionsTwo color options available in 2” rolls (natural and purple) for color coding purposesDisposableApplications Efficient and cost-effective covering for:Test tubesBeakersVialsPetri dishesFlasksVarious other instruments and objects with irregular surfacesOverwrap to further secure stoppers, lids and capsShelf or tray liner to prevent slipping of bottles or instrumentsPermeabilityOxygen: (ASTM 1927-98) 150 cc/m² d at 23°C and 50% RHCarbon Dioxide: (Modulated IR Method) 1200 cc/m² d at 23°C and 0% RHWater Vapor: (ASTM F1249-01) Flat: 1 g/m² d at 38°C and 90% RH Creased: 1 g/m² d at 38°C and 90% RHEffects of Common Reagents Potassium Permanganate5%: No apparent effect except permanent dark brown coloration in 18 hours0.1%: Same as 5% except slightly less colorIodine solution (0.1N)No effect except staining brown in 18 hoursEthyl Alcohol (95%)No apparent effect except some face whitening in 24 hoursNo apparent effect in 24 hours:Hydrochloric Acid conc.

It also prevents moisture and volume loss due to the material composition and tight seal. It can also stretch more than 200% of its original length and is disposable.Order a dispenser separately (1222J96/J97/J98).Parafilm® is a registered trademark of Bemis Company, Inc.
