INFORMACIÓN ADICIONAL
Moisture-proof film molds to surface
Parafilm® M is a semi-transparent, flexible, thermoplastic film with two-way stretch.
- Non-toxic and free from plasticizers, primarily composed of polyolefins and paraffin waxes offering good resistance against acids, alkalis and some organic solvents—use not recommended with acetone, diethyl ether or tetrachloride
- Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn’t release from glassware, despite off-gassing
- Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent
- Prevents moisture and volume loss due to material composition and tight seal
- Flexible and self-sealing material allows it to cling around irregular shapes and surfaces
- Stretches more than 200% of original length
- Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions
- Two color options available in 2” rolls (natural and purple) for color coding purposes
- Disposable

- Test tubes
- Beakers
- Vials
- Petri dishes
- Flasks
- Various other instruments and objects with irregular surfaces
- Overwrap to further secure stoppers, lids and caps
- Shelf or tray liner to prevent slipping of bottles or instruments
