Ideal for protecting samples and preventing contamination or evaporation—perfect for cleanroom environments and strict sanitation protocols. These pre-cut strips are sterilized using a Vapor Hydrogen Peroxide process, adding an extra layer of protection to Parafilm’s natural waterproof and moisture-resistant properties. Parafilm® M is a flexible, semi-transparent thermoplastic film designed for reliable sealing in laboratory, medical, and industrial environments. Engineered from a unique blend of waxes and polyolefins, Parafilm® stretches up to 200% of its original size, conforming tightly to irregular surfaces such as test tubes, beakers, petri dishes, and flasks. Each strip comes individually packaged in a sealed, lot-traceable pouch featuring a color sterilization indicator—ensuring both safety and convenience. * Packaged and Sterilized in USA * Sterile Expiration 2 years * Non-toxic, odorless, and semi-transparent * Creates a tight moisture barrier that holds a strong seal and doesn’t release from glassware * Prevents moisture and volume loss due to material composition and tight seal * The flexible and self-sealing material allows it to cling around irregular shapes and surfaces * Resistant up to 48 hours against saline solutions, inorganic acids, and alkaline solutions SPECIFICATIONS: * Dimensions (L x W): 4 x 6 in (10.1 x 15.2 cm) * Quantity: CS/50PK (5 per PK), equivalent to approx. 1 Roll * Sterile: True * Sterile Expiration: 2 Years
