Frequently asked questions
Does the film handle irregular container shapes well?
Yes, Parafilm M is highly adaptable. It is designed to be highly stretchable, capable of expanding up to 200% of its original length. This allows it to conform perfectly to irregular shapes, including flasks, beakers, and test tubes.
Is this film effective at preventing moisture loss?
Absolutely. Parafilm M creates a robust moisture-barrier specifically engineered to prevent volume loss and contamination, ensuring your samples remain protected.
Will this film allow for necessary gas exchange?
Yes, while the film provides a tight moisture-barrier, it is specifically designed to maintain gas permeability, allowing for the necessary gas exchange required in many research applications.
How long does the chemical resistance last?
The film offers excellent chemical resistance against many polar substances, including saline solutions, inorganic acids, and alkaline solutions, for up to 48 hours.
Is the material free from interfering odors?
Yes, the film is completely odorless and colorless, ensuring that it does not introduce any contaminants or unwanted scents to your sensitive laboratory samples.
Does it provide clear visibility of the contents?
Yes, the film is semi-transparent, which facilitates quick and easy sample identification without needing to break the protective seal.
How are the rolls stored for easy access?
The two rolls are housed in a convenient, functional cardboard dispenser box. This dispenser is designed to keep the rolls clean and organized while featuring instructional diagrams for easy access.
Can this film be used to seal different material types?
Yes, the self-sealing quality of the film allows it to cling firmly to various materials commonly found in labs, including glass and plastic, regardless of their geometry.
What is the total length provided in the set?
Each individual roll is 2 inches wide and 250 feet long. Since the set includes 2 rolls, you receive a total of 500 feet of laboratory wrapping film.
Is the seal secure if off-gassing occurs?
Yes, one of the primary benefits of Parafilm M is its superior sealing integrity. It is engineered to maintain a tight seal around glassware even when off-gassing occurs.
