Frequently asked questions
Does this film create a truly airtight seal?
Yes, Parafilm M is engineered to provide a superior moisture-proof barrier. Because it is thermoplastic, it can stretch to over 200% of its original length, allowing it to conform tightly to irregular shapes and surfaces to keep contents secure.
Is this film safe for sensitive laboratory samples?
Absolutely. Parafilm M is non-toxic and free from plasticizers. It is colorless and odorless, which ensures that it will not compromise the composition or integrity of your samples stored in vials, flasks, or petri dishes.
How flexible is the material during application?
The film offers exceptional flexibility with a two-way stretch capacity of over 200%. This makes it easy to manipulate and ensures it can be wrapped snugly around a wide variety of glassware geometries, from narrow test tubes to wider beakers.
Can it withstand exposure to common laboratory chemicals?
Yes, it provides robust chemical resistance for up to 48 hours against many polar substances, including:
- Saline solutions
- Inorganic acids
- Alkaline solutions
Are there any specific chemicals I should avoid?
While the film is highly resistant to many substances, it is not recommended for use with:
- Acetone
- Diethyl ether
- Tetrachlorid
Is this product made in the United States?
Yes, Parafilm M is proudly manufactured in the United States. It is fully compliant with both the Buy American Act (BAA) and the Trade Agreement Act (TAA).
What is the primary composition of this film?
The film is a high-performance thermoplastic material composed of polyolefins and paraffin waxes. This specific blend is what provides its unique combination of moisture-barrier protection and superior stretching capability.
Is the dispenser box easy to use in a lab?
Yes, the product comes in a functional cardboard dispenser box designed for efficiency. It features perforated areas that you can press through for quick and easy access to the film while keeping it organized and clean on your workbench.
How long will a single roll last?
Each roll provides a generous 125 feet of length at 4 inches wide. This professional-grade supply is designed to support high-volume research applications over an extended period.
Does the film stay secure if the sample off-gases?
Yes, one of the key benefits of this material is that it maintains a secure, moisture-proof barrier even when subjected to off-gassing, ensuring your research integrity is preserved throughout storage.
