Self-sealing, moldable thermoplastic film. 4" × 125' roll. Standard lab sealing solution.
The gold standard in laboratory sealing. Parafilm M is a semi-transparent, flexible, thermoplastic film that molds to virtually any shape. Simply stretch it over the opening of a beaker, flask, or test tube and it self-seals for a moisture-resistant barrier. Ideal for covering culture vessels, protecting samples from contamination, and sealing joints. This full-size roll (4" × 125') provides months of daily use.
