Parafilm Size 2×4 inch

Parafilm is a flexible, moldable, and waterproof film that is widely used in laboratories for sealing or protecting containers. It’s made of a blend of waxes and polyolefins, which gives it its unique properties.

Common Uses of Parafilm in Laboratories:

1. Sealing Containers: It’s often used to seal test tubes, beakers, flasks, and petri dishes to prevent contamination or evaporation.
2. Protecting Samples: Parafilm can be used to protect samples from exposure to air or moisture, helping to maintain the integrity of the sample.
3. Covering Instruments: It can be used to cover and protect instruments that are not in use, keeping them clean and free from dust.
4. Wrapping Lab Items: Parafilm is sometimes used to wrap around items like pipette tips, stoppers, or other tools to keep them secure.
5. Temporary Labeling: Its smooth surface allows for temporary labeling with a marker, which can be useful in identifying samples or containers.

Characteristics of Parafilm:

• Stretchable: Parafilm can stretch up to 200% of its original size, making it very versatile.
• Self-sealing: It adheres to itself, which is handy for creating a tight seal.
• Resistant: It is resistant to many common laboratory chemicals, though it can be dissolved by some solvents.
• Non-toxic: Safe to use with sensitive samples and in various laboratory environments.
