Parafilm is most commonly used for sealing and protecting vessels such as test tubes, cuvettes, and petri dishes. Since Parafilm is both stretchy and self-sealing, it is easily used on lab containers of all shapes and sizes. Beyond these typical lab applications, many additional uses have taken advantage of the hydrophobic nature of the film.
